upstairs loo is fine but downstairs loo has just started to fill up loads when it is flushed and then returns to low level slowly
also the low level it returns to is slightly lower than normal
had pipes/drain jet washed last september as downstairs loo kept filling up then - bloke said they should be done around every 18 months or so (he checked mine and neighbours drains and said all were blocked)- cant believe it needs doing again?
sil reckons it might just be all the rain and to leave off forking out for a plumber just yet
what do you think?
