We’re having a WBosch combi boiler fitted to our 1930s semi, and the guy from Eon only measured the mains water pressure at 10 psi from the outside tap. Plumber here today says 10 psi is on the low side and it may need a mains pressure booster pump fitting to up the incoming pressure to the boiler, is this normal please?
Can anyone recommend a good mains booster pump to go under the sink by the stopcock?
