Hi,
We're having a problem with drainage!
Toilet flushes ok, but then fills the pan with water & takes ~5-10 sec to get back to the correct water level. On "full flush" this also causes the bath plug hole to gurgle somewhat. Bathroom sink seems to drain ok. Bath drains a little slowly, but not too bad.
Kitchen sink drains very slowly.
Tried using drain unblocking fluids in bath & kitchen, plus attacked the blockages with a plunger. Both seemed to help a little, but not fully fixed the issue.
Also tried filling the bath before draining so as to give a good head of water to push through any blockages, again no real improvement.
Only been a problem for the last two or three days, it was all running fine prior to that.
Any ideas please??
Thanks!
