We have the landlady from hell, who is trying to charge us for an emergency plumber that she called out when our shower overfilled. The shower has always been really slow to drain, and we have had to use unblocker about once a month, which just can't be right! Never had these problems in any previous property we've lived in.
I was wondering if there was any regulations on the minimum pipe size / flow rate that a shower needs to be able to cope with. Just from feeling around it with my finger it doesn't seem like there is any big opening for the water to go into. I'm going to try and take pics tonight.
Any help would be much appreciated!
If you live in West London and help me defeat this landlady witch I'll buy you a pint!
