Thanks for coming back to me.seen these before, try drain cleaner, would guess pipe partly blocked with hair and soap scum,
do NOT use caustic soda as that can set in the pipe and make thing worst ,
go to plumbers merchants and ask for advice, there are some things you can use,
but i am unwiiling to state as if you hurt your self i do not wish to be blamed, sorry,
Hi Guys,Usually advise my customers to remove the shower head from the shower hose and direct the water from it on fully cold into the waste, this in most cases will flush through any debris trapped in there if it's hair then it may require a chemical to dissolve this and aid flushing process. Kop
