Kitchen plumbing installed without correct waste pipe gradients, incorrectly seated traps, or supply connections without isolation valves will cause problems quickly. Slow draining, persistent under-sink leaks, and sewer smells returning within weeks of the job being completed are all signs of installation errors that are straightforward to avoid when the work is done correctly from the start. At EBT Build, every kitchen plumbing installation follows WRAS guidance on pipe gradients, trap specifications, and joint integrity before any system is tested and signed off.

Poor kitchen plumbing work is one of the most common causes of under-sink cabinet damage in UK properties. Loose compression fittings, incorrect waste pipe gradients, P-traps not seated correctly, and isolation valves fitted without testing — these are the installation errors that cause slow draining, persistent leaks, and sewer smells that return within weeks of the job being completed. At EBT Build, every kitchen plumbing installation follows WRAS guidance on pipe gradients, trap specifications, and joint integrity before any work is signed off.

Kitchen plumbing costs in North London vary depending on the scope of work required. A standard kitchen sink installation including trap, waste pipe, and hot and cold supply connections typically costs between £150 and £350. Kitchen tap replacement costs between £80 and £200 depending on the tap type and whether supply connections require upgrading. Dishwasher plumbing connections typically cost between £100 and £200. Full kitchen plumbing installations as part of a new kitchen fit out or layout change will cost more depending on the pipe run lengths, number of appliances, and whether any drainage or venting alterations are required. EBT Build provides a fully itemised written quote after a free site assessment so you know the exact cost before any work begins.
Under-sink leaks are almost always caused by loose or incorrectly fitted compression joints, worn or cracked trap components, failed flexible hose connections between the tap and supply pipes, or a P-trap that has not been seated correctly. Over time, vibration from the waste disposal or dishwasher can loosen fittings that were not tightened adequately during installation. Leaks at the sink waste outlet are typically caused by a failed putty or silicone seal between the waste fitting and the sink bowl. EBT Build carries out a full under-sink inspection before any repair is quoted to confirm the source of the leak before any components are replaced.
Slow kitchen sink drainage is most commonly caused by grease and food debris build up in the P-trap or waste pipe, an incorrect waste pipe gradient that does not allow water to flow freely to the drain, or a venting problem causing negative pressure in the waste system. Incorrect pipe gradients are a common result of under-sink plumbing that was installed without checking falls before the waste pipe was fixed in position. EBT Build inspects the full waste system including trap condition, pipe gradient, and venting before recommending a repair to ensure the underlying cause is addressed rather than just clearing the immediate blockage.
A standard kitchen sink installation including trap, waste pipe, and supply connections typically takes two to four hours. Kitchen tap replacement takes one to two hours depending on the tap type and the condition of the existing supply connections. Full kitchen plumbing installations as part of a new kitchen fit out or layout change take longer depending on the number of appliances, pipe run lengths, and whether any drainage or venting alterations are required. EBT Build confirms a clear timeline before any work begins so you know exactly how long the job will take.
Yes. We install dishwasher supply feeds, waste connections, and non-return valves on all dishwasher installations across North London. We also carry out plumbing connections for washing machines, boiling water taps, water softeners, and fridge freezers with ice makers and water dispensers. Every appliance connection includes correct supply feed installation with isolation valve, waste pipe connection at the correct gradient, and a full test under operating conditions before the installation is signed off.
Yes, in most cases. Relocating a kitchen sink requires extending or rerouting the hot and cold supply pipes to the new position, rerouting the waste pipe to maintain a correct gradient to the drain connection, and confirming that the new waste pipe run can be adequately vented. The feasibility of a sink relocation depends on the distance from the existing drain connection, the floor construction, and the route available for the new pipe runs. EBT Build assesses the new sink position and pipe routing options during the site visit and advises on the most practical approach before any work is agreed or priced.
