Washing machine waste not draining properly

[Oliver Dawson]

Can anyone see where this piping is wrong?

The w/m waste overflows from time to time. Also comes up
Can’t empty sink while washing machine is on.

Any info advise much appreciated

Doesn't appear to be anything wrong with the pipework per se, it's more likely blocked somewhere. Where does it go after exiting the cupboard?

Have you checked the trap for blockages?

I’m not sure

not sure , only have a pic from customer. I’ll clean out traps. Should the waste pipe be angled to run slightly down? I was thinking it may need adjusting.

The customer has done in the past but says it comes back sooner than expected. Any idea of how often it’s expected to clear out a trap? Could a level pipe or not angled enough pipe be an issue?

Depends on how much fat/grease goes down

Only if a backfall, that appears ok. You need to check the waste pipe downstream of the traps.

Good point will do thanks
