I am thinking to solve the problem of low water pressure from the cold water tank. My house has a bath with a shower, a shower room, first floor toilet, ground floor toilet, i.e. a normal house like everyone else has. Due to the water pressure is from the cold water tank on the loft, the shower, the basin taps, even the toilets fill valves are working very slow. I am thinking to install a water pump direct connect the cold water tank output to boost the water pressure. So the whole house will be having a higher water pressure. Is it feasible and practical?
