Hi there,
I was hoping you good folks could help with a issue I've encountered on a new 1700x700mm bathtub refit.
The issue is it takes forever to drain - I mean abnormally long @ +10 mins.
Starting at the compression end of the standard P trap, a 25cm length of waste pipe takes the flow 'back' towards the rear wall before elbowing into a 165cm length which terminates outside into a rainwater hopper. Looking at the waste pipework from a birds eye perspective, it would form a 'L' shape. I've used 40mm pipe and a compression elbow. The wash basin has its own waste and therefore the bath isn't connected to anything else apart from whats described above.
The 165cm length has a nice visible drop of approx 50mm. The shorter 25cm from P trap to elbow is flat and I can't see how to create a pitch on such a short run. The 'L' shape was necessary as the waste pipe can only be run BEHIND the bath legs.
Do you think its the 25cm flat run causing the issue? What can I do to fix that?
Being a complete newbie, the bathtub isn't perfectly level along the length - the spirit level is only slightly out at the rear. I can't see how that could cause this as I tested with the bath FULL. But can this be a cause too?
