Leaks and blockages

Some things leak (still can’t get the hot water tank to stop slightly leaking even after the third mend) and other things block. I won’t go into detail about where this pipe is from…but let’s say there is a certain chemical reaction between seawater and ‘x’ which makes calcium. Old pipe, previously not used much, now solid and very blocked…

Russell valiantly cleared the blockage and cleared up….(in 38 degree heat) whilst I took the boys round the excellent (and wonderfully air conditioned) aquarium. I think we got the better deal!
