A couple of year ago my Dad fitted a shower in our upstairs bathroom. Since then we have had a leak coming through the ceiling, my Dad has had several attempts at fixing it but has never managed to stop it completely.
We have become worried about the constant leak from the shower and decided to fit a bath instead.
When my Dad took up the floorboards I noticed that he has cut away some of one of the joists underneath the shower to fit the pipes for it. The beam measurements are roughly 8 x 3inches and he has cut away about 3 inches down and 3 inches across to fit the pipes.
I don't want to call a plumber and pay if it is ok but what I really wanted help with is does anyone know if this is safe?
I know nothing abut DIY but am concerned about fitting a bath over the joist that has been altered.
Also any ideas what the constant leak could be?
We also have a new leak at the join of two pipes. My Dad said that when they were taking out the old shower they accidently loosened a joint, how would this be fixed?
