taydo, you said it was illegal to use a pump on a mains water supply but in the water regs guide G6.1 says that you only need written approval from the water undertaker if a pump connected directly or indirectly to the supply pipe draws more than 0.2 litres per second.

why don't you get them back in? You've paid a lot of money so they should leave you with a properly functioning system. If they can't make it function properly shouldn't they pay the cost of someone else coming in to fix the problems for you?

My understanding is that the optimal position for the pump is after the vent and feed pipes on the flow pipe. Also the vent and feed pipes should not be further than 150mm apart on the main pipe. This is copied from "Plumbing" by Treloar: "The cistern must be placed in such a location that...
