Hi all

Ever since we had a new washing machine fitted there has been a terrible TCP taste to our kitchen cold water. I believe that this might be caused by water from the washing machine hose backflowing into the cold water supply.
I have been doing my best to research my problem and I understand that the solution is to fit a single check valve so that water standing in the hose does not get drawn back into my drinking water when I operate the tap.
However what I can't find out is specifically where to fit this. I know nothing about plumbing or what pipe is what and so the arrangement under the sink is a complete mystery to me. Perhaps someone could draw me a diagram? I have attached a picture.


Thank you

Hi tyshapuzzle,
Before you go to the trouble of fitting a check valve suggest you turn off the valve next to the hose connection when you are not using the washing machine. See if this cures the problem.

Okay will try that first. Thanks
