Waste pipes from washing machine leaking

[Madrab]

Get rid of all the grey pipe fittings, push fit couplers are terrible things, replace the connection up to the sink trap too.

As suggested replace it all with solvent weld (SW), apart from the final connection that drops into the floor, that will need to be compression and fit a proper standpipe with trap where the current drain hose is fitted into. If SW is beyond you then replace the couplers with McAlpine compression fittings.

Do you know what's under the bottom shelf as far as connections are concerned, if that's the same push fit then there may be trouble lurking under there too.

Terrible?

Neither are we shown where & how the WM stand pipe discharges or if it is trapped with a typical compression trap?

It has a running trap, it is shown in the photo.

Thank you for correcting me.
However, my phone screen only showed as far down as the shelf - my PC monitor now shows the full pics - so I deleted my incorrect post.

Terrible?

Yep - no self respecting pro that I know would use it, invariably it is a leak waiting to happen.

Hi Hugh, there are no rubber seals on any of the fittings.

Well, that as said, would explain the leaks!

Madrab has already given excellent advice, if you're confident working with solvent weld pipe/fittings, that is the way to go.

Fit a Washing Machine Trap/Standpipe instead of replicating the existing plethora of bends, if you need to provide for Two drain hoses, look at the McAlpine fitting that will sit on top of the Standpipe and allow both hoses to connect. https://mcalpineplumbing.com/traps/domestic-appliance-traps-accessories/twin-connector/

Really? How do you know that your "self respecting pro's" wouldn't use push fit applications?
Did you know that push fit allows for expansion & contraction esp. with S&V stacks - gullies -ground work drainage, even clay pipework?
Its something most "self respecting pro's" would know?

Oh please - don't go there. We are talking specifically about push fit 32mm and 40mm waste pipe for internal domestic waste runs serving basins, baths, sinks etc. that is prevalent in the pictures
I am not talking about main drainage, soil pipe or any other larger gauge pipework where ring seal fittings are a secure, sturdy and well accepted, standard - when fitted properly and tested - but that is a completely different product and application to that grey push fit waste in the pics

Do you have meetings where you discuss such matters - such as that push fit always leaks?

Actually yes, it's called a toolbox talk - or a tea break - where we all used to get together on site and discuss our work - push fit waste and it's downfalls always seemed to raise it's head every now and again, especially by the young apprentices who didn't know any better and it always turned into a slagging match about how bad it was and why no-one would ever use it
