Does anyone know what is the difference between negative head, positive head and right pumps? Which one should I use if I am going to put in near the shower and the water tanks are far away somewhere on the roof?
Hello all,
I have been reading the forum for quite a while, found a lot of useful information.
I have a problem with low cold water pressure in a top floor flat. It is on the 8th floor of a ex-council estate block. Both hot and cold water are supplied, so I don't have any boilers or tanks...
