Worn or Damaged O-Rings and Washers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>What happens:<\/strong> Inside every basin faucet, rubber O-rings and washers create the watertight seal that prevents water from escaping around the spout base or handle joints. Over time, these rubber components harden, crack, or flatten under repeated compression and thermal cycling. When the seal degrades, water seeps through the gap\u2014often appearing as a slow drip from the <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/basin-faucets\/\" target=\"_blank\" rel=\"noopener\">robinet de lavabo<\/a> spout or a trickle around the handle.<\/p>\n<p><strong>Why it matters for B2B buyers:<\/strong> In hospitality and commercial projects with dozens or hundreds of faucet units, O-ring wear is the single most frequent maintenance call. Selecting faucets with <strong>high-quality, durable seals<\/strong> (like FAAO&#8217;s brass cartridges with precision-engineered O-rings) dramatically reduces after-installation service costs.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_to_Fix_It\"><\/span>How to Fix It<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ol>\n<li><strong>Turn off the water supply<\/strong> \u2014 Close the angle valve under the basin. If no angle valve is present, shut off the main water line.<\/li>\n<li><strong>Disassemble the faucet<\/strong> \u2014 Remove the handle (usually a small screw under a decorative cap), then pull out the cartridge or stem.<\/li>\n<li><strong>Inspect the O-ring<\/strong> \u2014 Look for cracks, flattening, or discoloration. A healthy O-ring should be round, flexible, and uniform in color.<\/li>\n<li><strong>Replace with the correct size<\/strong> \u2014 O-ring sizes vary by faucet model. Use the exact replacement specified by the manufacturer. FAAO provides replacement O-rings compatible with each product series.<\/li>\n<li><strong>Reassemble and test<\/strong> \u2014 Reinstall the cartridge, handle, and decorative cap. Turn the water back on and check for leaks.<\/li>\n<\/ol>\n<h2 id=\"cause2\"><span class=\"ez-toc-section\" id=\"2_Corroded_or_Damaged_Valve_Seats\"><\/span>2. Corroded or Damaged Valve Seats<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>What happens:<\/strong> The valve seat is the brass or stainless surface inside the faucet body that the washer presses against to stop water flow. If the valve seat becomes pitted, corroded, or uneven\u2014common in faucets made from low-grade metals\u2014water bypasses the seal even when the washer is in good condition. This produces a persistent drip from the <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/basin-faucets\/\" target=\"_blank\" rel=\"noopener\">basin faucet spout<\/a>, often noticeable when the faucet is fully closed.<\/p>\n<p><strong>Why it matters for B2B buyers:<\/strong> Valve seat corrosion is directly tied to <strong>material quality<\/strong>. Faucets manufactured with high-purity brass (like FAAO&#8217;s CZ122 brass bodies) resist corrosion far better than those made with recycled or zinc-rich alloys. For procurement teams sourcing <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/basin-faucets\/\" target=\"_blank\" rel=\"noopener\">robinets de lavabo<\/a> for humid or high-use environments, material grade is a critical differentiator.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_to_Fix_It-2\"><\/span>How to Fix It<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ol>\n<li><strong>Remove the faucet cartridge<\/strong> \u2014 Follow the same disassembly steps as Cause 1.<\/li>\n<li><strong>Examine the valve seat<\/strong> \u2014 Use a flashlight to inspect the interior surface. Pitting, rust spots, or uneven surfaces indicate corrosion.<\/li>\n<li><strong>Resurface the valve seat<\/strong> \u2014 For minor corrosion, use a valve seat wrench (a specialized tool that smooths the surface). This restores a flat sealing surface.<\/li>\n<li><strong>Replace the faucet if corrosion is severe<\/strong> \u2014 Deep pitting cannot be resurfaced effectively. In this case, replacing the entire faucet with a high-quality brass model is the cost-efficient solution\u2014especially in commercial settings where downtime is expensive. Consider FAAO&#8217;s <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/basin-faucets\/\" target=\"_blank\" rel=\"noopener\">basin faucet collection<\/a> for corrosion-resistant replacements.<\/li>\n<li><strong>Test the repair<\/strong> \u2014 Reassemble, restore water flow, and verify the drip has stopped.<\/li>\n<\/ol>\n<h2 id=\"cause3\"><span class=\"ez-toc-section\" id=\"3_Loose_or_Improperly_Sealed_Connections\"><\/span>3. Loose or Improperly Sealed Connections<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>What happens:<\/strong> Basin faucets connect to the water supply through flexible hoses or rigid pipes, typically fastened with nuts at the faucet base and the <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/angle-valves\/\" target=\"_blank\" rel=\"noopener\">angle valve<\/a>. If these connections loosen over time\u2014due to vibration, thermal expansion, or initial under-tightening\u2014water leaks at the joint. You&#8217;ll typically see water pooling under the basin or dripping from the supply line connection.<\/p>\n<p><strong>Why it matters for B2B buyers:<\/strong> In multi-unit installations (hotels, apartment complexes), loose connections are a top source of emergency maintenance calls. Using faucets with <strong>precision-machined threads<\/strong> et <strong>factory-tested connection seals<\/strong> (standard in FAAO&#8217;s manufacturing process) reduces this risk significantly.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_to_Fix_It-3\"><\/span>How to Fix It<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ol>\n<li><strong>Locate the leak point<\/strong> \u2014 Dry all connections with a towel, then turn on the water and watch for the first drip. Mark the exact location.<\/li>\n<li><strong>Tighten the connection<\/strong> \u2014 Use a wrench to gently tighten the nut at the leaking joint. Avoid over-tightening, which can crush the sealing washer and create a worse leak.<\/li>\n<li><strong>Replace the sealing washer if tightening doesn&#8217;t work<\/strong> \u2014 Remove the nut, extract the old washer, and install a new rubber or fiber washer of the correct diameter.<\/li>\n<li><strong>Check the <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/angle-valves\/\" target=\"_blank\" rel=\"noopener\">angle valve<\/a> connection<\/strong> \u2014 If the leak is at the wall-side connection, ensure the angle valve itself is secure and its internal seal is intact.<\/li>\n<li><strong>Test thoroughly<\/strong> \u2014 Run water at full pressure for 2\u20133 minutes and inspect all joints.<\/li>\n<\/ol>\n<h2 id=\"cause4\"><span class=\"ez-toc-section\" id=\"4_Cracked_or_Degraded_Cartridge\"><\/span>4. Cracked or Degraded Cartridge<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>What happens:<\/strong> Modern single-handle <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/basin-faucets\/\" target=\"_blank\" rel=\"noopener\">robinets de lavabo<\/a> use a ceramic cartridge to control water flow and temperature. While ceramic discs are highly durable, the cartridge housing (typically plastic or brass) can crack under impact, freeze damage, or manufacturing defects. A cracked cartridge leaks water continuously\u2014often from both the spout and around the handle\u2014regardless of whether the faucet is open or closed.<\/p>\n<p><strong>Why it matters for B2B buyers:<\/strong> Cartridge quality is the heart of faucet reliability. FAAO uses <strong>35mm ceramic cartridges<\/strong> from certified suppliers, tested to 500,000+ cycle lifespans. For projects requiring long-term reliability\u2014commercial buildings, rental properties, hospitality\u2014cartridge grade is a decisive purchasing factor.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_to_Fix_It-4\"><\/span>How to Fix It<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ol>\n<li><strong>Shut off water supply<\/strong> \u2014 Close the angle valves under the basin.<\/li>\n<li><strong>Remove the handle<\/strong> \u2014 Pry off the decorative cap, unscrew the handle screw, and lift the handle off.<\/li>\n<li><strong>Extract the cartridge<\/strong> \u2014 Pull the cartridge straight up. Some models require a cartridge puller tool.<\/li>\n<li><strong>Inspect for cracks<\/strong> \u2014 Look for visible cracks, chips in the ceramic discs, or mineral deposits inside the cartridge body.<\/li>\n<li><strong>Replace with the manufacturer&#8217;s specified cartridge<\/strong> \u2014 Cartridges are model-specific. FAAO provides exact replacement cartridges for every faucet series. Using an incompatible cartridge can cause immediate leaks.<\/li>\n<li><strong>Reassemble and test<\/strong> \u2014 Insert the new cartridge, reinstall the handle, restore water, and check for leaks at all positions (hot, cold, mixed).<\/li>\n<\/ol>\n<h2 id=\"cause5\"><span class=\"ez-toc-section\" id=\"5_High_Water_Pressure_Stress\"><\/span>5. High Water Pressure Stress<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>What happens:<\/strong> Standard basin faucets are designed for water pressure between <strong>0.5\u20131.0 MPa (50\u2013100 PSI)<\/strong>. When supply pressure exceeds this range\u2014common in high-rise buildings, municipal systems with pressure boosting, or poorly regulated commercial plumbing\u2014the faucet&#8217;s internal seals and components are stressed beyond their design limits. This accelerates O-ring wear, strains cartridge discs, and forces water through micro-gaps that would otherwise remain sealed.<\/p>\n<p><strong>Why it matters for B2B buyers:<\/strong> High water pressure is an invisible cause that turns a quality faucet into a frequent service item. For procurement teams, the solution isn&#8217;t just buying better faucets\u2014it&#8217;s ensuring the entire plumbing system includes proper pressure regulation. FAAO&#8217;s <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/basin-faucets\/\">robinets de lavabo<\/a> are pressure-tested at 1.6 MPa to exceed common operating ranges, but system-level pressure management remains essential.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_to_Fix_It-5\"><\/span>How to Fix It<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ol>\n<li><strong>Measure water pressure<\/strong> \u2014 Attach a pressure gauge to an <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/angle-valves\/\" target=\"_blank\" rel=\"noopener\">angle valve<\/a> outlet. Read the static pressure (faucet closed) and dynamic pressure (faucet open).<\/li>\n<li><strong>Install a pressure-reducing valve (PRV)<\/strong> \u2014 If pressure exceeds 1.0 MPa, install a PRV at the main supply line. Set it to 0.5\u20130.7 MPa for optimal faucet performance.<\/li>\n<li><strong>Verify with a second gauge reading<\/strong> \u2014 After PRV installation, re-measure to confirm pressure is within the safe range.<\/li>\n<li><strong>Replace any damaged faucet components<\/strong> \u2014 High pressure may have already degraded O-rings or cartridges. Replace these even if the PRV has been installed.<\/li>\n<\/ol>\n<h2 id=\"cause6\"><span class=\"ez-toc-section\" id=\"6_Mineral_Buildup_and_Hard_Water_Deposits\"><\/span>6. Mineral Buildup and Hard Water Deposits<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>What happens:<\/strong> In regions with hard water (high calcium and magnesium content), minerals precipitate inside the faucet body, around the spout aerator, and on internal sealing surfaces. Over time, this buildup creates a rough, crystalline layer that prevents O-rings and washers from forming a complete seal. The result: slow, persistent leaks from the <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/basin-faucets\/\" target=\"_blank\" rel=\"noopener\">robinet de lavabo<\/a> spout or handle area, often accompanied by visible white or green scale deposits.<\/p>\n<p><strong>Why it matters for B2B buyers:<\/strong> Hard water is a regional variable that procurement teams must account for when specifying <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/basin-faucets\/\" target=\"_blank\" rel=\"noopener\">robinets de lavabo<\/a> for projects in affected areas (common in Middle East, South Asia, and parts of South America).

Improper Installation or Wrong Faucet Type<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>What happens:<\/strong> A basin faucet designed for a single-hole installation won&#8217;t seal correctly on a three-hole basin\u2014and vice versa. Incorrect mounting hole alignment, missing gaskets, overtightened mounting nuts (which warp the base gasket), or using a deck-mount faucet on a wall-mount basin all create leak pathways at the faucet base. This type of leak appears immediately after installation, making it easy to identify but costly to fix if the wrong faucet was purchased in bulk.<\/p>\n<p><strong>Why it matters for B2B buyers:<\/strong> This is a <strong>specification error<\/strong>, not a product defect\u2014yet it&#8217;s one of the most expensive mistakes in commercial procurement. Ordering the wrong faucet type for a project means either field modifications (which compromise quality) or full replacement.

The seal surface is no longer smooth enough to stop water flow completely. Replace the O-ring first\u2014it&#8217;s the cheapest fix. If the drip continues, resurface or replace the valve seat. In commercial settings where downtime is costly, consider upgrading to a FAAO basin faucet with a ceramic cartridge, which eliminates washer-based seal failure entirely.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Can_I_fix_a_leaking_basin_faucet_without_calling_a_plumber\"><\/span>Can I fix a leaking basin faucet without calling a plumber?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Yes, for most common causes (O-ring replacement, connection tightening, aerator descaling). These repairs require basic tools: a wrench, screwdriver, and replacement parts. However, if the leak involves <strong>valve seat resurfacing<\/strong> ou <strong>cartridge replacement<\/strong> in a concealed or wall-mounted faucet, professional installation is recommended to avoid damaging surrounding tile or plumbing. FAAO&#8217;s technical team can provide model-specific repair guidance\u2014contact us at <a href=\"https:\/\/www.fuaocn.com\/fr\/contact-us\/\" target=\"_blank\" rel=\"noopener\">FAAO Support<\/a>.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_often_should_O-rings_and_washers_be_replaced_in_a_basin_faucet\"><\/span>How often should O-rings and washers be replaced in a basin faucet?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In residential settings, quality O-rings typically last <strong>5\u20138 years<\/strong>. In commercial\/high-use environments (hotels, hospitals, office buildings), lifespan drops to <strong>3\u20135 years<\/strong> due to higher cycle frequency and water pressure. FAAO&#8217;s precision-engineered O-rings, paired with brass cartridges, extend this interval by approximately 30% compared to standard components. Proactive replacement during scheduled maintenance prevents emergency leak calls.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Is_a_leaking_basin_faucet_a_sign_that_I_need_to_replace_the_whole_faucet\"><\/span>Is a leaking basin faucet a sign that I need to replace the whole faucet?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Not necessarily. If only the O-ring or washer is worn, a simple replacement restores full function. However, if you observe <strong>multiple failing components<\/strong> (O-ring + valve seat + cartridge), visible body corrosion, or the faucet is incompatible with the basin, replacement is more cost-effective than cumulative repairs\u2014especially for B2B procurement where total cost of ownership matters. FAAO offers <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/basin-faucets\/\" target=\"_blank\" rel=\"noopener\">leak-resistant basin faucets<\/a> designed to minimize the most common failure points.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_water_pressure_range_is_safe_for_basin_faucets\"><\/span>What water pressure range is safe for basin faucets?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Standard operating range: <strong>0.5\u20131.0 MPa (50\u2013100 PSI)<\/strong>. Pressure above 1.0 MPa stresses internal seals and accelerates wear on all components. FAAO basin faucets are factory-tested at <strong>1.6 MPa<\/strong> for a safety margin, but sustained operation above 1.0 MPa still shortens component life. Install a pressure-reducing valve (PRV) at the building supply line if pressure exceeds safe range, and verify with a gauge reading.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Does_hard_water_cause_basin_faucets_to_leak\"><\/span>Does hard water cause basin faucets to leak?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Yes. Hard water (high calcium\/magnesium content) deposits minerals on internal sealing surfaces, creating a rough layer that prevents O-rings and washers from forming a complete seal. This is a significant factor in regions like the Middle East, South Asia, and parts of South America. FAAO basin faucets feature <strong>chrome-plated interiors and anti-scale aerators<\/strong> that resist mineral adhesion. For buildings in hard-water zones, a water softener at the supply level provides the best long-term protection.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_can_I_tell_if_my_basin_faucet_cartridge_is_cracked\"><\/span>How can I tell if my basin faucet cartridge is cracked?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A cracked cartridge typically produces a <strong>continuous leak from both the spout and around the handle<\/strong>, regardless of whether the faucet is open or closed. You may also notice the handle feels loose or doesn&#8217;t turn smoothly. To confirm, shut off water, remove the handle and cartridge, and inspect for visible cracks or chips in the ceramic discs. If found, replace with the manufacturer&#8217;s exact cartridge model. FAAO provides model-specific cartridges for every <a href=\"https:\/\/www.fuaocn.com\/fr\/faucet\/basin-faucets\/\" target=\"_blank\" rel=\"noopener\">faucet series<\/a>.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Whats_the_difference_between_a_basin_faucet_leak_from_the_spout_vs_from_the_base\"><\/span>What&#8217;s the difference between a basin faucet leak from the spout vs. from the base?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A <strong>spout leak<\/strong> (drip when faucet is closed) points to internal seal failure\u2014O-rings, valve seat, or cartridge. A <strong>base leak<\/strong> (water around the faucet mount on the basin deck) points to installation issues\u2014missing gasket, wrong faucet type, or overtightened\/under-tightened mounting nuts. Different leak locations require different fixes. Use the Quick Diagnosis Checklist above to match your symptom to the correct cause.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Are_brass_basin_faucets_less_likely_to_leak_than_zinc_alloy_faucets\"><\/span>Are brass basin faucets less likely to leak than zinc alloy faucets?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Significantly yes. <strong>High-purity brass (like FAAO&#8217;s CZ122)<\/strong> resists corrosion, maintains dimensional stability under thermal cycling, and provides a durable valve seat surface. Zinc alloy faucets corrode faster, warp under heat, and develop internal pitting that destroys sealing surfaces. For commercial and hospitality projects where longevity matters, brass basin faucets deliver 2\u20133x the leak-free lifespan of zinc alloy alternatives.
