Hi,
we have just renovated our old bathroom. It used to have a bath and sink all flowing in the same 40mm waste pipe along a straight run into the soil stack. 2.5m length
we have now introduced a separate shower. All the wastes flow into the same 40mm waste pipe, shower first then the bath then the sink. There was no option due to height restriction that the wastes could be attached to the soil individually. Joist space only.
The shower has a non return valve on it which prevents the tray filling when the bath empties, the sink as an air admittance trap on it which prevents the gargling, but the bath drains very slowly. Its a huge bath 255 litres approx. and takes about 10mins to drain. the pipework is all new to the bath. The run is approx. 3m through a few 90 degree bends.
I have checked the pipework for blockages and everything is clear. Granted the pipework is almost level whilst running through the joists but there was no other option.
At some points whilst the bath is draining it seems to stop! I cant figure it out why the water wont flow. Any help??????
