Positive Head

A positive head shower pump is designed to be gravity fed, therefor it needs a 'head' of distance (at least a metre) between the pump and the bottom of the cold water cistern. The gravity feed 'kick-starts' the pump, pushing water straight through to your shower.

    My 16 year old ShowerForce EasyBoost pump started to leak. I'm very pleased I chose to replace it with a Grundfos Watermill Amazon 2.0 Bar Twin Positive Head STP-2.0B brass pump. Plumbworld, kept me informed by email about delivery and the pump was very well packed. The pump installation was straight forward but I redesigned the 22mm pipework in my airing cupboard to allow for a possible future feed to a second shower room; this required careful design. I fitted Pegler full bore lever valves to the tops of each of the 4 supplied flexible tails to make isolation for periodic cleaning of the pump filters a simple matter. I placed the pump on a 300mm x 300mm x 25mm granite paving slab and insulated this from the wooden floor boards with strips of "P" profile 3-5mm gap Stormguard EDPM door/window seal. The bathroom is next to the airing cupboard and the shower head is 330mm below the bottom of the cold water tank. With the pump fitted, but switched off, flow through the Pegler Mimo thermostatic mixer valve (min. 0.1 Bar) and Groher eco (min. 1 Bar input and restricted 9 l/min flow rate) shower head was approx. 0.7 litres per minute. When the pump is switched on and the shower valve is opened, the pump starts fine and delivers approx. 8 l/m. The noise of the old pump was much louder than the sound of water from the shower head but the new Grundfos pump cannot be heard over the sound of the shower water. The noise from the pump in an adjacent bedroom is no longer intrusive and would be unlikely to disturb a sleeping child.

    This is a great shower pump. I bought it to replace a plastic bodied pump bought from a DIY store a couple of years ago. That pump failed leaving water leaking through the ceiling of the room below. I ordered this pump because it had great reviews and haven't been disappointed, it is much quieter than the pump it replaced and much more powerful. The push fit connections make fitting it into an existing installation a breeze, I hardly even needed the toolbox. Plumbworld had the best price for this unit and have given great service with quick delivery, they even accommodated my request to change delivery location when I realised I wouldn't be around to accept delivery at the original address. I'm hoping the pump gives long and trouble free service.

    Very impressed with the superb service supplied by Plumbworld. Everything was very smooth and easy to do and the delivery was fast. The pump itself replaced an older grunfos wasp pump which I'd had for at least 10 years. This pump is a lot quieter than the previous one, so much so that I had to check it was on as I didn't hear it!! It allows both showers in the house to be used at the same time with no apparent drop in pressure. Grundfos are well established and I know I could have got a cheaper pump but you pay for what you get and in my humble opinion Grundfos is a reliable make. Overall extremely pleased with the purchase and the professional way that Plumbworld dealt with the whole process from start to finish. Would definitely highly recommend.

    I ordered this pump to replace an old Aura45 that was in the house when we moved in 8 years ago it was very loud heard all over the house. What a difference really quiet when running should keep others sleeping on those early starts. Solid brass finish worth the bit extra and 5 year cover. I fitted full bore valves as nothing there before for maintenance, bit of pipe repositioning needed as flex hoses fairly rigid. Really impressed with the service from Plumbworld called them up to check manufacturer part number, as was given this from Grundfos ordered over the phone and arrived next day as promised via DHL.

    I wanted to change my old 1.5 bar salamander pump serving a single shower to an uprated pump to serve two showers. Having compared the specs; reviews and prices of various pumps I decided to go for the Grundfoss watermill Amazon 2 bar pump. I was not disappointed, I could see immediately this pump was a well engineered piece of quality kit.
