Hi, I have been told that I need to have a negative head pump installed to increase the preassure of the hot water system in my house.
I just wanted to know what the difference is between this type of pump and a positive head pump or a standard water pump and if I could use something else in it's place as I'm trying to keep costs down and these pumps are quite expensive.
Thanks.
