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.

Sick and tired of poor performance from your shower? With this fantastic new addition to the Grundfos range you can finally relax in showering bliss.

    Unfortunately, my shower pump died on Monday. I spoke to Plumbworld as to what pump it need to replace my faulty one with. They were very helpful. I ordered it online that afternoon and it arrived on Wednesday morning. It was so easy to replace (as long as you know where to switch off your hot and cold supplies to the pump) as it only took me 20 minutes. i also order the anti-vibration mat and I must say it is so much quieter and seems to have a little more pressure than my old one. As i mentioned delivery was super quick and i was kept updated with the order/dispatch and delivery at all times. So to sum it up. A fantastic pump and a fantastic service from Plumbworld, will definitely use them again. Massive thankyou!!!!

    As we all know Grundfos make the best pumps! And it is true, mine made a bit of noise but a thin sheet of polystyrene soon stopped that. Also as an advantage, it does run two showers although it only states one, albeit the pressure is a bit low, but that depends on the actual head of water that is available. Altogether a very good pump.

    Didn't want to purchase a salamander as I'd heard they weren't that great, this seems to do well, with clear instructions on how to get the most out of the pump. Easy to wire up as well.

    Easy to fit, worked straight away. I did swap the pipes out for 15mm connections. As only 22mm supplied.
