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.

    It's taken me a while to write the review as I have been waiting to complete the bathroom, however used the newly installed pump today and WOW it's fantastic the presure is bang as advised by the tech team. It run's both the overhaed showewr head and the wall mounted shoer head also, with out any change in presure. I would higly recommend the pump and Plumpworld as the delivery was as notified with no damage to the box and the after sales team followed up the delivery at least on 3 occasions. Thanks for your help everyone, FANTASTIC service allround.

    Extremely satisfied with product especially as we bought it with a £150 saving whilst on offer. We have been fed up with rubbish pressure from our showers for years and the water pressure from the shower now is excellent. We are enjoying our showers so much now that we have stopped having a bath at night and have another shower instead!! Thoroughly recommended to other customers and arrived promptly after ordering so completely satisfied with plumbworld. 100% satisfaction.

    This pump was purchased to replace an old Mira which has given us great service over the years.This Grundfos pump, knocks the socks off the Mira and is a supreme product. I can't believe how well it works and how quiet it is compared with the old one. There is no vibration it is a miracle pump. The quality of it and the ease of fitting in my view couldn't be surpassed. It also comes with all fittings to enable an easy exchange. Great value for the money.

    This is a very well built machine which has quality written all over it. It is supplied with 4 good quality flexible push fit hoses. Most importantly it works brilliantly, delivering a deluge but making very little noise. It was delivered next day and the price was the best I could find. Very very highly recommended for both product and service, many thanks.

    This pump provides a powerful jet of water even when the shower valve is half open. It is quiet running and really looks and feels like a sturdy, well manufactured product. The price was significantly lower than that quoted by local merchants and delivery was very prompt.

    I bought this to replace a Stuart Turner 1.5 bar pump. The new pump is great, not really quieter, but it's not a real issue for me. It seems very well made and is very sturdy. Just beware, due to the power of this pump, your hot water will run out sooner!!!

    Pump needed professional installation due to the inabiliy to release the original push-fit fittings. One up and running it is great to have the power shower back and this pump is quieter than the last one so all is well.

    Quite compact and much quieter than my previous pump, also a good make but 13 years old. Plenty of power for the two showers on two floors - would recommend. Ask me again in 13 years time!
