What's most important to know? It pumps water maybe?
I like the fact that it pumps water much faster than gravity feed alone. Much, much faster! Neither does it introduce air into the water through the motor like the Chinese brass units I bought, trying to save money. I dislike the fact that it doesn't pump out double chocolate ice-cream, diamonds or even gold coins. Very disappointed in that regard! Could do better. I used it as a shower pump. That's probably because it's a shower pump and to use it as a lawnmower would have been silly and may not have yielded the expected results, though it could easily be modified..... Who writes these questions? Who answers them?!! Have these sad people got nothing better to do? Who reads this nonsense anyway? Joking aside, buy one if your bath or shower only trickles or takes your full 4 minute allotted E.U. Eco Carbon Credit Quota just to get wet, let alone soapy. (How can anyone have a proper shower in only 4 minutes? I must be doing something wrong. No, not that! I don't take nail clippers and shampoo into the shower; I just want to wash and go!). The pump is very fast, (probably a 2 pole 2880 rpm motor), powerful and fairly quiet depending on how it's fitted but it's not silent, then again, neither is your hair dryer and you don't mind that. Unless you're like me. (By the way, pay the small extra for one with ceramic motor bearings as the standard hairdryers all wear out after a few years and my red Babyliss Ceramic with integrated cable recoil has lasted about ten so far with no signs of packing in yet, touch plastic). Back to the shower pump, the copious volumes of cool, refreshing water coming out of the spray head will make more noise hitting you in the earhole than the actual pump so it's all about air in the pipes and isolation from vibration. Comprehensive fully English fitting instructions are included if rather small printy. Mine is connected by 19mm bore, flexible 22mm pipes and connectors, sat temporarily on a 2 inch bed of folded up foam rubber and you can buy pump mats though you've probably got something just as good around the house. There are 4 rubber feet but on chipboard flooring it'll still be amplified. Try to place it on a joist but don't screw it down. If you can place it on solid brick or concrete, then the feet will work just fine on their own but the pipes themselves will always be the main source of noise. The flexible hoses included say they shouldn't be bent more than 30 degrees so bear that in mind. They will flex but they're still fairly stiff. You can buy solid copper pipe with a helical rolled thread so it will hand-shape to fit a curve by the way, if you don't have a pipe bender. It's a very well balanced unit so doesn't want to walk or hop about and takes a 5 amp fuse, though the rating is actually 1.8 amps @ 420watts, 240v so a red 2 amp fuse would probably suffice. The instructions say it should only be used with an RCD and be wired directly into a mains switch but not on the immersion heater spur, which is fair enough. Mine is on a 3 pin plug for testing porpoises. If they like it, I'll wire it in permanently! So, how does it perform? Well, my non-pumped 'gravity' pressure would allow about a five or six inch fountain of water if I held the shower head upside down on full blast, both hot and cold together. The addition of a cheap pump raised this to about a foot, maybe even 18 inches and was a big improvement. This pump will hit the ceiling and is more than enough pressure. You'd probably want a 3, 3.5 or 4 bar pump for a tower wall unit with 5 massage jets on it but for a single head on a combined bath/shower tap, it's perfect. Ironically, after 26 years of using hardly any water, I've just been switched to a metered supply! I use mine with one of those clear, 'ionic' three pattern shower heads and it's easy to start and stop flow with the push of a button. The pump quietly switches on and off automatically without hammering the pipes so you don't have to turn the taps on and off between wetting and rinsing and can keep your temperature settings until you finish. Both the pump and on/off shower head are highly recommended!

Decent pump
A decent increase in pressure. Mine is mounted under the floor fully sealed crawl space and although you can hear it when running it is much quieter then the other one installed in other bathroom

Easy to Install - Works Better than Rivals
My old pump (a different cheaper make fitted about 6 years ago) was always temperamental. The pressure valve turned the pump off with the shower set at the hot position. The gravity-fed water pressure was fine on the hot and cold supply and confirmed by a professional plumber. The old pump issue gradually worsened over the years until it stopped working altogether this weekend. Decided to try a more expensive pump, ordered it last night and fitted it by 11 am this morning. Happy that this Britan pump works perfectly with all temperature positions of the shower unit and provides a powerful flow. Hope it lasts!

Quiet.
I recently purchased this item to increase the flow of cold water from my tank to electric shower. It did exactly what I required. It’s located in the loft and compared to a Salamander pump I’ve had previously, this is very quiet. The pressure has increased as required, it’s good quality and great value for money

Do not buy this shower pump
This pump was fitted for 6 weeks and totally failed. Amazon refer you to the manufacturer for any faults/warranty issues with it but Bristan do not want to know as it was not directly bought from them, even though it is sold by Bristan Store. To make the matter worse, Bristan in their warranty terms and conditions state that if the unit fails it must not be uninstalled until inspected. Now if like me, it is fitted to your only bath and shower it could be weeks before you can actually wash again..... Some of the worst customers service I have ever had the misfortune to deal with. Minus 10 stars at best. Update - I have now read in detail their terms and conditions and what it actually states is '5.1.2 Should we so require, we must be given every opportunity to inspect and test the goods concerned, if at all possible in situ as first installed, and we will need to see our applicable batch and delivery note details'. Therefore they also lie on their email correspondence to try and squirm out of warranty claims. This is what was sent to me 'Unfortunately, as you have advised your pump is no longer installed, it is no longer covered under the manufacturer’s warranty for replacement parts. As per the terms and conditions of our warranty, which can be read using the link below, the product must be in situ for inspection if needed for testing or inspection for manufacture fault. As the pump has been uninstalled, we cannot carry out this diagnosis. If you would like to return the pump for a refund you will need to discuss with the retailer that you purchased the product from directly.'
