Bristan 2 Bar Single Ended Shower Pump, Improves Shower Pressure and Easy to Install, Water Booster and DIY Fixing Kit with Instructions, 230 Volt - ST PUMP20SG

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!

Seems good product been working for months. Easy to install

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

Totality transformed our shower experience . Easy to install hopefully it will last us a few years

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

with a water tank in the loft and hot water tank in the bedroom there was not enough pressure to run the shower in the bathroom or even the downstairs shower. The pump took minutes to fit, just cut a section of pipe out of the hot and cold supplies after turning the water off, brought longer 22mm flex push on hoses and pushed them on, plugged the pump in and job done. Both showers have superb pressure now. not to noisy, but no pump is quite, after a few days you do not notice it. Update:- pump lasted about 6 months before becoming very noisy and starting to leak everywhere. Seller honored the warranty and provided a replacement pump but refused to install it because I had fitted longer flex hoses which they tried telling me was the cause of the leak. As if water knows the difference in length of a straight flexi hose. The new pump was installed by a plumber who made a dogs dinner of installing solid copper pipes to reach the short stubby pump supplied pipes. The new pump is so noisy it is unbearable to use, especially when you flush the toilet or the washing machine is on. Will look for a better make pump that runs quietly.

I chose to write this review in order to express how happy I am with this product... I had lousy water pressure to my shower (balanced pressure on a Y plan hot water storage system) I’m not a plumber but this was easy to fit, I had to buy longer hoses due to my setup but all in it stands me at £200 to fit myself but £200 well spent. I mounted the pump in the loft on a board on top of insulation and it’s pretty quiet, I can’t hear it in the master bedroom (a modest sized house) You know it’s on when in the shower but it’s not an annoying buzz or hum, just a subtle noise. This pump has turned my shower from a poor excuse for getting a bit wet to a fantastic experience. (The rainfall head pictured was useless previously, there wasn’t enough pressure in my system and it just stalled flowing up the outlet pipe with little or no water flow at all, now i can use this head and angle the flow. All in all I’m very happy from delivery to ease of installation to the end users experience. Only dilemma I have is do I buy another for my second shower 🤔 I think so!!!
