    My previous pump was the same make but an older model. It had lasted over 10 years and I have been very pleased with it. This new model fitted exactly the same as the previous one so no need to move pipes etc. It runs a lot quieter in fact to start with I had to leave the shower running to make sure the pump was working as I could not hear a sound. I am very pleased with this pump and will highly recommend it to anyone looking for a shower pump.

    this was on offer at a special discounted price. Our Plumber suggested it, as apparently Stuart Turner pumps are highly regarded. Plumbworld were courteous and helpful and went out of their way to make sure we received the product the following day, which was a Saturday! So we were all able to enjoy an excellent shower that evening. The pump is powerful and not really noisy at all. Excellent!

    Sorry I did not put my review earlier, as the plumber who said he would install this for me let me down twice. I now have this pump installed and it is superb. I had a differnt make of pump before costing a lot more, and not as good as this. GROHE. This pump was a lot more from other suppliers.

    So pleased we found Plumbworld, their product range, prices and service was second to none. This pump was to replace a worn out shower pump, it arrived well packed was easy to install and works better than our previous pump. Would highly recommend.

    Easy to fit straight from the box without any fuss. Sited this one in the airing cupboard next to bathroom. Can hear the pump running but not particularly loud. Very pleased with choice. Good product representing good value for money.

    Delivery time fast - Price surprisingly cheap - pump quiet, powerful and easily fitted and hopefully reliable. Only criticism delivered when we were out and the delivery company left it outside in the rain.

    just fitted one of these with no drama. Not too noisy compared to others (and I cant notice any difference compared to a top of the range Salamander). Just ordering another one for next job.
