Just moved into a 10year old house, bathroom and en-suite wc's are back to back, sharing same drain. Drain runs horizontally left to right with about 600 - 700mm between connections.
WC1 ------- WC2-------- TO EXTERNAL DRAIN
Problem is that wc1 seams to get a back flow from wc2 causing staining in the water and occasionally floating "debris!
wc1 is only used ccassionally while wc2 is mainly used.
Both wc's are on same level with little or no horizontal run in drain pipe.
Only solution is to flush wc1 to keep water in bowl clean!
No space to run separate drains, any ideas?
