I've finally managed to remove the bath panel tonight, as the tub has been draining incredibly slowly. I thought this was due to soap and hair build up so was expecting to have to pull a load of crap out. Instead the trap was clean. But I discovered a few things which have been confusing me.
Firstly the plumbing under the tub is a bit odd, there is a normal p trap and then a second u bend made out of elbows under the bath. Could this be because there used to be a tub with a drain in the middle?
Weirder still, when I disconnected the overflow Flexi pipe to clean that, I noticed a constant trickle of water backing up and into the bath waste into the tray underneath. See video.
What the heck is going on? The bath and sink share some common plumbing, and there has started to be a lot of gurgling as the sink drains. The drainage from the bath has never been great, but the backing up is getting progressively worse over the last few months.
