Washing Machine Plumbing: Supply Options
1: SELF-CUTTING CONNECTORS
The simplest way of joining to the existing hot and cold pipes is to use self-cutting connectors. As long as the taps on the fittings are kept closed, you don’t even have to turn off the water.
Each connector has a clamp which you fit around the supply pipe, and a stoptap which theninto the clamp. The stoptap inlet contains a circular cutter that automatically breaks through the pipe wall, plus a washer to guarantee a watertight join.
Various makes work slightly differently, but two main types of stoptap are available. Within reach of the washing machine hoses, choose taps with threaded outlets that allow you to attach the hoses directly. For connections some way from the machine, opt for taps with compression fittings on the outlets so you can run branch pipes as in Supply Option 2, and then fit hose connectors to the pipe ends.
1. Decide where to site the stoptap, then offer up the clamp to the pipe. Some types fix to the wall, in which case drill and plug, thenin place.
2. Screw the clamp body together over the pipe. Some are in two parts while others are hinged. The clamp body has athread inside to accept the tap body.
3. Screw the tap body into the clamp until it’s hand-tight. Some types need an extra quarter of a turn with a spanner. Adjust the tap body so it is vertical.
4. The tap shown is threaded for direct hose connection. With the sealing washer inside the plastic hose connector, screw it on and tighten with a spanner.
2: BRANCH PIPES WITH TEES
The conventional way of supplying a washing machine is to turn the water off and insert tee fittings in the supply pipes. From here, you run branch pipes to a point near the machine and fit compression-jointed stop-taps with threaded outlets to accept the machine hoses.
3: STOPTAP TEE FITTINGS
This is a variation of Option 2, used where the connections to the supply pipes can be made close to the machine, but where you aren’t allowed to use self-cutting connectors.
Instead, you cut the supply and fit compression jointed tee fittings with built-in stop-taps. As with Option 1, these allow the hoses to be attached direct.
