Water in two toilets turning brown - Help

[nigel]

Hi all,

We have two toilets upstairs one in bathroom and one in adjacent ensuite - they are about 3 m apart and both empty into same horizontal soil pipe - the down stream toilet is about half metre from stack where shared soil pipe discharges

Water in toilet pans turns brown even when not being used - is it sludge in soil pipe seeping back in as there is no fall - both loos are on same floor level

Is it OK under building regs to fit loos like this? House was built 10 years ago by big builder

Any thoughts gratefully received - Thanks all N

In the situation you are describing, water will be back-flowing to WC due to no fall or (worse) a rise from the WC. Sadly in newer houses it's fairly common to see this. People fitting paid peanuts by the builders and having to rush the work to make any money.

2 WCs on the same horizontal branch is fine as long as falls are correct. Current regulations allow up to 8 WCs to be connected on one branch pipe. The correct fall is 18-90mm per metre so a fairly substantial fall is required.

The only time I have seen water turning the pans dirty & brown was from a rain water harvest system!

I've seen it before but the toilets were back to back and one of them was plumbed up with the branch pipe running uphill from the toilet.

Found out the hard way when I removed the toilet from the wall. As it was a back to wall toilet I couldn't really see the slight slope until I removed it..

Wasn't one of my nicer days in the job that one!

Try some of this


Highly unlikely to be drainage related but get a pro in for an on the job opinion. Might cost a bit more than the domestos tho :smile:
