I had a leaky hot water tap on a shower, so I replaced the plastic rubber O ring bit inside and this stopped the leak.
But two weeks later (and possibly unrelated) the same tap when you turn it on puts out no water, it takes about 1 minute for water to start coming out.
I am guessing I have a leak in this line. But the pipe goes directly through a solid double concrete wall to the hot water system so there is no access what-so-ever. Because its on the hot water line I can't see my meter moving and I haven't noticed my hot water service filling unusually.
Does anyone have any ideas on how to figure out what is going on?
