5/ 5

Pros: Powerful, Quiet , Solid

Cons: None

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.

Pros: Compact size good quality great value for money

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.

Pros: Easy to install, Value for money, Well Made

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!

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.

5/ 5

Pros: Very easy to fit any not to unsightly.

Cons: Nothing

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.

Pros: Everything

Cons: None.

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.
