I'm in the middle of modifying my ground floor toilet, moving the toilet pan and hand basin positions. The toilet pan is not a problem as it goes back into the position it was about 4 years ago, the hand basin is where I've got an issue.
There is a 110mm horizontal soil pipe laid in the floor with one end into the vent stack and the other turned up with a 87.5 deg bend which is capped of with a 110 to 50mm eccentric reducer at floor level.
I want to connect the 32mm basin waste, along with a single 40mm waste from a double kitchen sink and a dishwasher, into the 110-50mm reducer. The distance from the common point of the double sink and dishwasher connection is about 2 metres and the hand basin sits almost directly above the 110 -50mm reducer.
There seems to be several ways to connect these items together but I'm not sure which would be the best.
A) I could connect the 40mm waste from the double sink and dishwasher into 110-50mm reducer via a 87.5 deg bend, and then connect the 32mm hand basin waste into a 40mm 'Tee' in the 40mm waste.
B) I could connect the 40mm waste from the double sink and dishwasher into 110-50mm reducer via a 40mm 'Tee' connector, and then connect the 32mm hand basin waste into that 40mm 'Tee' connector.
C) I could connect the 40mm waste from the double sink and dishwasher into 110-50mm reducer via a 50mm 'Tee' connector, and then connect the 32mm hand basin waste into that 50mm 'Tee' connector.
