    I bought this pump as a replacement for my existing showermate shower pump which seemed to have got very temperamental. Upon installing the pump it hadn't resolved the problem. It was actually a blockage in the shower valve inlets that was causing my shower pump not to work. Plumbworld were understanding and allowed me to return the purchased pump and gave me a full refund. As I am selling my house you can imagine how pleased I was not to have this extra expense. The pump itself is easy to install which I did myself with no problem. From this experience I am definitely using plumbworld in future. The prices were competitive and the customer service was exceptional, refund was paid without delay. Thank you, thank you, thank you.

    When my shower pump leaked in the airing cupboard, I discovered that it was not covered by the BG homecare insurance! Perhaps I should not have been too surprised. Anyway, rather than electing for the BG replacement pump and fitting charge (in excess of £500!), I searched yhe Plumbworld website and found a suitable replacement (infact better, higher rated pump presure). significant savings on cost pricealthough it wasn't in stock, but expected in a couple of days. Turned out it was 3 days but I was kept informed by e-mail. Pump duly arrived, well packed. Has now been fitted and working well. Great product at a great price, with friendly service! Highly recommended, 5* etc etc. Thanks.

    I have fitted quite a few Stuart Turner pumps over the past couple of years for customers and have found them to be reliable and powerful. The instructions are clear and they come with everything you need for a straight replacement in the box. This is not the prettiest of pumps in all fairness and Id have liked isolator valves on all four of the hoses (like on their larger pumps) rather then only the 2 inlet hoses. It isnt over loud but Id suggest not fitting it onto a floor and using a vibration absorbing pad under. The customer is very happy with the resulting power when I replaced her old pump and I would definitely fit these in the future for a single shower.

    This pump was a replacement for the equivalent pump installed about 10 years ago. I did not realise how noisy the old one was until the new one went in. If this one does as well i'll be happy. Asked for next day am delivery and it was delivered before 9.30. The price was well below the next best so full marks Plumbworld

    What a difference a pump makes! Every morning I dreaded my shower, wondering if it would work properly or even at all. Then like magic, Stuart Turner changed my life, fantastic hot water with a whisper not a gurgle and splutter. Would I recommend you as a company and your products? yes any time.
