Plumbing and maintenance
Plumbing in washing machines and dishwashers safely
Appliance connections are a common source of slow leaks because the fittings sit hidden behind the machine for years.
How the system behaves
- Standpipes need the correct height and an
- air gap; a hose pushed too far down a standpipe can siphon and refill the drum.
- Self-cutting valves on old pipework are a
- frequent long-term leak source; a proper tee and isolator is more reliable.

Questions we get asked
Can a machine share a waste with a sink?
It can connect to a trap spigot, provided the trap and fall are correct.
Why does my machine smell?
Often residue in the hose or trap, and sometimes a drainage arrangement that lets waste sit in the hose.
Want the awkward part looked at first?
Access, existing pipework and floor build-up are the things that change a plan. Those get checked before anything is promised.
