Modifications to shower wastepipe

[TonyAsh]

hello, like most caravans the wastepipe from shower and washbasin is connected to the wastepipe from the kitchen sink. When the washbasin plug is removed to empty the grey water the kitchen sink plug pops out of the plughole, (if the sink is full of water).

I am a bit sick of this and have decided to modify the pipework, this is my question.....

Where can I purchase the waste pipe and joints of a diameter to suit the existing waste pipework? or can one obtain adapters to use 1.25" diameter pipe whic is easily available. I would prefer rigid waste pipe rather than the flexible pipe.

Thanks in anticipation. Tony

Try this company http://www.leisureshopdirect.com/caravan/water.

I think 1 1/4" is the same as 28mm

Thanks Mikey, I have looked at the website and yes it's all there.

1.25" converts to 31.7mm

Cheers Tony

If you can change to a simple Y junction it solves the proplem.

Outlet from bathroom and kitchen sink go in the top of the Y and the pipe to the waste tank outlet goes on the bottom of the Y.

Water and pressure are then directed towards the outlet, problems caused by T junctions solved!
