FLOPLAST WHITE ADJUSTABLE APPLIANCE HALF P TRAP 76mm SEAL x 40mm

Think of the FloPlast White Adjustable Appliance Half P Trap 76mm Seal x 40mm as a sink trap and an appliance connection in one. It is a tubular P pattern trap with a 40mm horizontal outlet, a 76mm water seal, and a spigot on the side for a washing machine or dishwasher drain hose.

P pattern appliance trap: when to pick it

Go for the P pattern when the waste pipe leaves through the wall behind the sink and you have a little space below the bowl. Tubular traps flow freely and are easy to rod, which helps on a busy kitchen sink that also carries appliance water. If space is very tight, the bottle version may suit better.

How to fit it, from a Glasgow plumbers merchant

Take the old trap off and check the sink waste thread is clean and undamaged. Fit the new trap with its washer, hand tight, and line up the outlet with the wall pipe. Push the drain hose onto the spigot and hold it with a hose clip. Make sure the hose rises well above the trap before it comes down, so dirty water cannot drain back into the machine. Then test the sink and the machine together.

Common Questions

Which side does the appliance spigot face?

Line the trap up so the spigot points towards the machine before you tighten the top nut. That keeps the hose run short and tidy.

Why must the drain hose loop up high?

A high loop behind the machine stops sink water running back into the appliance. Most machine makers show the height in their instructions.

Is the TW473 the same size as a normal sink trap?

It fits a standard 1 1/2 inch sink waste and joins 40mm pipe, so it can replace an existing sink P trap.
