Hi,
My plumber fitted two new showers - a Bristan Colonial Thermo mixer with a fixed Victorian Can shower head and a Triton Mini Petita Thermo Mixed with a flexible hose fitting.
After installation the water pressure, especially on the Bristan was very poor. Our plumber convinced us to install a shower pump so I bought a Salamander RSP50 1.5Bar Twin Right Shower Pump.
The old showers were never the fastest in the world but perfectly adequate in terms of water flow.
The plumber fitted the pump and added a Salamander S Type Flange (22mm) to the hot water tank. He also renewed the whole pipework from cistern to pump and the pump to showers (which are fitted at floor level in the airing cupboard on the first floor - the showers are also on the first floor - below and beside the tank).
The showers work well when engaged, but the Bristan won't start the pump unless we trigger it by turning on the other Triton shower. When you turn on the Bristan, there's no water coming through at all until the pump is started - not even a trickle.
The plumber messed around with the plumbing, added new valves and vents etc but to no avail.
I read on the Bristan FaQ that a Negative Head might be required.
Can anyone help as I just seem to be pouring cash into a money pit at the moment...
