I need help fitting a washing machine standpipe

[glassofpop]

Currently my washing machine waste pipe is connected to the trap under the sink and due to bad plumbing I think my washing machine is having problems pumping out so I've bought a standpipe and floplast solvent weld pipe and floplast bends but the bends are to tight on the pipe so I'm going to buy another brand so can someone recommend what brand solvent weld pipe I should buy and what bends do I need to buy as I don't know if I need swept bends or 90 degree bends.

When I run the pipe outside can you tell me which is the best way of doing it from the drawing. Number 1 is how it is now so I was thinking of doing it like number 2 but there isn't any room in the drain so if I do it like number 3 what solvent weld connector will I need to connect the two pipes.

Sweeping bends offer less resistance, either way is ok, but you’ll need a Tee.

What is the issue you are having, connection to the sink trap is a common solution. Problem may well be with way the drain hose is configured rather than the waste Pipework. Can you get any photo's?

may be some photos ,

i have moved from a standpipe to sink waste for washing machine - no issues
and also have dishwasher on a different sink waste, previously had a standpipe and separate pipework to outside drain , just consolidated that when refitted the kitchen
and same in old house - again changed outside w/mch from standpipe

Your waste pipe should not be higher than the trap outlet and yours is even higher than the washing machine hose.
This is not helping your problem.

Oh dear - there's one of your problems. As suggested, the outflow pipe through the wall should not be higher that the outlet of the P trap. That appliance spigot is also in a strange place, so not sure what make of adjustable trap that is but that doesn't look quite right either. The waste run needs altered. That and the elbow marked 'want to replace' is solvent welded (glued) onto the pipe heading out the back and can only be cut off. Only way to change all that so it is configured properly is to drop the pipe, that's heading out the back of the cabinet, down lower. Not knowing where that pipe goes makes it hard top advise, if it heads outside then a new hole will be needed through the wall. The cabinet back will need to be opened up to get access to start.

Floplast and their fittings aren't too bad. I typically use OSMA but I source all my materials from my supplier but I have used Floplast before in a pinch and haven't had an issue, they may be tight but that's not a bad thing.

As above, the issue is with the waste being too high where it goes through the wall. You really need to reroute the waste pipe to go through the wall at a lower height, then make good the existing hole after the pipework has been removed.

Currently you're pretty much asking water to run uphill.

The pipe is going through the cupboard and straight out the wall. The part I marked longer do you know if you can buy theses any longer or is there a connector to try and make something.

I've had the council out and they said there's nothing wrong with it.

There's lots wrong with it and you've been told that waste water does not run uphill.The pipe going through the back of that unit needs to be lowered.You need a new hole drilled lower down as you have been told above.

They're quite simply lying, there's everything wrong with it. It might drain but it won't drain properly and all that white pipe will always be full of water. It just isn't right

The part I marked longer do you know if you can buy theses any longer

No - why longer?

 

[glassofpop]

No - why longer?

I was hoping the water would drain faster if the elbows where removed and a longer pipe fitted.

How many times?

Shiit don't "drain" uphill!
