Urinal Repair & Commercial Washroom Plumbing Clapham

Uric scale in the waste pipe holds the odour, not the bowl. Descaling the pipework and correcting the flush regime removes it properly.

Yes — scheduled visits covering urinals, cisterns, sensor taps and TMVs, with reports for facilities and compliance records.

Common urinal problems include blocked outlets, slow drainage, continuous flushing, weak flushes, leaks and unpleasant smells. Urine scale can narrow waste pipes, while worn seals or faulty flush controls can cause water loss. Smells may come from deposits, a dry trap or an exhausted waterless cartridge. Stop using a urinal that backs up or leaks, and isolate its water supply if safe. A plumber can identify whether the fault is in the flushing mechanism, trap or waste connection.

A urinal that keeps running usually has a flush valve that is not closing, debris in the valve, or a faulty sensor or control. On a cistern-fed system, check whether the cistern is repeatedly refilling because its inlet valve is stuck. Isolate the local water supply before investigating, and do not dismantle pressurised fittings. An engineer can clean or replace faulty valve components and check the controls. Shared automatic systems may flush periodically by design.

First check whether the urinal has a weak flush or whether water enters normally but drains slowly. Weak flushing can result from a restricted supply, blocked spreader holes or faulty flush controls; slow drainage usually points to scale or a blockage in the trap or waste pipe. Stop flushing if the bowl starts filling. Avoid mixing cleaning chemicals or using boiling water. A plumber can clear restrictions and test the flush mechanism without damaging seals or pipework.

To fix a leaking urinal, first stop using it and isolate its water supply if you can safely reach the valve. Dry the surrounding area and check whether water appears at the flush pipe, bowl or waste connection, without removing fittings. Common causes include worn seals, loose connections, blockages and cracked ceramic. Do not overtighten fittings or cover a failed joint with silicone. A plumber can replace the correct seal, clear a blockage or replace a damaged bowl.

Urinal repair starts by identifying whether the fault affects flushing, drainage or watertightness. Isolate the supply before dismantling water fittings, and stop using the urinal if it leaks or backs up. Repairs may involve servicing a flush valve, replacing a pipe seal, clearing scale from the trap or fitting a manufacturer-approved waterless cartridge. Cracked ceramic generally needs replacement. The final checks are secure fixings, a sound waste connection and leak-free operation during repeated flushing.

A urinal gasket is a sealing component fitted between connected parts to prevent leaks. The term often refers to the seal between the urinal outlet and its waste connector, although flush connections also use seals or washers. Depending on the fitting, it may be rubber or another specified sealing material. A hardened, displaced or damaged gasket can allow water or odours to escape. Replacements must match the particular connection and urinal design.

To find the right urinal gasket, identify the urinal manufacturer, model and the connection that is leaking. Check the parts diagram or installation instructions for the specified replacement. If those are unavailable, measure the mating connection and compare the old gasket’s internal diameter, external diameter, thickness and profile. An old seal may have stretched or compressed, so measurements alone are not always reliable. Match the shape and material as well as the size; avoid stacking seals.

There is no single standard size for a urinal gasket. Dimensions vary with the urinal model and whether the gasket seals the flush inlet, waste outlet or another connection. A waste pipe’s nominal size does not necessarily equal the gasket’s measured diameter. Use the manufacturer’s part reference where possible, or match the internal diameter, external diameter, thickness and profile to the fitting. A seal that merely looks close can still leak or prevent the connector seating correctly.
