I've just installed a shower with a shallow trap, and I used the wrong gradient for the waste pipe. It's about 2.5m with a couple of bends, 40mm pipe. I incorrectly thought that 1:40-1:80 would be ok but this is the wrong waste gradient!
In order to achieve 18-90mm per metre I'd have to go throught the external wall and round the corner of the house. This would mean 4 turns rather than the current two, is it worth doing? Also, would using two 135° bends as a pair rather than a single 90° help flow?
Thanks,
Mark
