Negative Head

When you want to install a shower pump which is situated level or slightly above the cold water tank, then you need a negative head pump  The negative head pump sucks water from the tank which feeds straight to your shower.

Stuart Turner Showermate Continuously Rated Motor

Continuously Rated Motor

Continuously rated shower pumps effectively run until the user turns it off. This is particularly good in a family home where the shower needs to be used frequently throughout the morning or evening. A pump that isn’t continuously rated will turn itself off to allow the pump to cool, potentially causing issues with water pressure to the shower.

    Needed to replace pump, only 2 1/2 years old with, I suspect, a U/S PCB. Expensive kit to fail after only 2 1/2 years but Grundfoss will apparently service items less than 5 years old. Yet to see how good that service is. As far as PlumbWorld is concerned, they provided great delivery at the best price on the Net.

    Cannot believe I am excited by a pump but I am. This is a real beast with incredible power yet surprisingly quiet. Great price and excellent service from Plumbworld. Tour De force with my new Mira Agile Sense ERD+ also from Plumbworld. Thanks.

    We wanted a new pump to operate our steam cabinet. The Grundfos pump was a good price for a negative head pump and it works beautifully. It arrived quickly and was well packaged. Fitting it was easy and we can now enjoy a steam!!
