Water Regulations & Washing Machines

[watertight]

Guys and Gals

Apologies if I've posted on the wrong forum. Spoke to a customer today who requested that I paid a visit to her house. She had a washing machine delivered by Currys the other day. Upon delivery she was told that they would not plumb it in due to the waste pipework being too long as published in the Water Regulations.

I wasn't aware of any maximum length for waste pipework for an appliance such as a washing machine. Is anyone able to educate me further on this?

1.7 metres for 32 mm and 3 metres for 40 mm.
Any longer and the bore of the pipe needs to be increased ar AAvs need to be added.

Sorry.

Should read larger bore pipes needed OR you need to fit an Aav
