we have a new shower fitted. The shower tray has a bevel and a rectangular removable waste cover. We have removed the cup that was in the waste as the water wouldn’t drain fast enough. Still the water manages to get past the shower screen edge and soak the floor. Is the only option to put an edge round the unscreened part of the shower tray or is there a waste which could deal with the volume of water. Thanks
Has the waste pipe been installed correctly, terminating properly and with correct gradual fall and supported fully? Often they are installed wrong and water will back up. No good if waste has no fall or has a dip in middle which will fill with water and airlock
Did the old shower drain ok and was a new pipe fitted or the old one altered in any way? Was a different type of shower fitted.
Get the installer back as shower not fit for purpose Who supplied and decided on spec for shower and tray, etc Is there a particularly massive flow of water due to loads of water pressure or 3 bar pump and/or large ‘ rainfall’ shower head fitted Maybe a high flow waste trap was needed but not fitted or any of the above issues as well, ie, poor install Have you been in touch with the installer and how long ago was shower fitted
The 'cup' referred to may be an integral part of the waste, designed to act as a trap preventing foul odours escaping.
how long ago ? every shower drain/trap has to meet the minimum british standard or the european equivalent for water discharge Some adverts for shower drain/traps can mention,high flow,high discharge capacity,super fast discharge etc. Thats all advertising ! Usually the lower shower tray profile demands the best shower drain installation with appropriate materials,its all easily fixed but can be costly
The waste is about 8 ft long with a drop of about 2 ft. It is a large shower head so would imagine that there is quite a water flow although it is a gravity shower. I was just wanting to know if there are any high spec waste that might make a difference
which shower waste is fitted ? As an example some advise they can shift 25 L/min But for that discharge they need 20mm a constant (head) of standing water above the shower waste. tbh,looking for a debris/air blockage would be the first investigation
