I have a washing machine which is plumbed into the drain with a standard sort of appliance trap:
There's a nozzle for the appliance, an outlet connector which clamps onto the waste pipe, a P-trap, and a sink connector on the top.
The only thing is, i don't have a sink!
Well, not right next to the washing machine, at least. So currently, i have the sink connector open to the air. Most of the time, this is fine, but if the washing machine drains a particularly foamy load of water, then the foam shoots up out of the top, and spills all over the place.
Can i somehow seal the top of the trap? Is there a blanking plug which will fit this?
I had a look, but all the plugs i could find are for the connectors which joins to other bits of pipe, not the connector which joins to the sink, which seems to be different. The sink connector is a plain pipe with a threaded nut around it; the dimensions are:
- Internal diameter of pipe 33.8 mm
- External diameter of pipe 41.2 mm
- Internal diameter of nut thread 45.5 mm
Is there something which will fit this?
