SP2B Flowflex in Line Micro Pump, The Shower Power Booster is an Easy, Efficient & Effective in Line Micro Pump, DIY Solution to Poor Water Pressure, Suitable for All Plumbing Systems.

Brilliant.Installation was fairly easy. I had very little room to work in and too long a spanner - with proper tools and/or a bigger airing cupboard it would've been a piece of cake. It took me probably a bit less than an hour, I then had to fit a plug socket in my airing cupboard which took about 20 mins.I don't think there's much they could do to make installation easier really. Maybe include a pipe slice or offer an option that can be wired directly in directly. Who has sockets in their bathroom? All in all though I can't complain, it didn't take long to fit and I learned a few things along the way.Performance is great. Just brilliant. My shower literally did not work before. Maybe a little dribble on a good day. Now it works very well, with the small quirk of having to turn on a hot water tap first to get the pump going. It does have a manual mode, so I could wire up a switch or hook into the lights, etc but I'm happy enough with it like this. It could a limitation with the mixer shower we have.Hot water pressure is noticeably improved throughout the house. It seems to take about half the time to run a bath now. It really is brilliant, I can't overstate how good this thing is. Everyone's house and plumbing is different of course so your milage may vary.It is a little bit noisy. I can't really hear it at all in the bathroom but you can hear it in the next room and the kitchen which is underneath the bathroom. Mainly only when it's powering down, it groans for a few seconds.I haven't used any other hot water pumps but did look at reviews and installation videos for a Salamander pump. The Salamander would be considerably more expensive and probably not DIY friendly. I can say without a doubt that this beats the Salamander on cost and ease of installation. I imagine the Salamander would perform a bit better (it'd have to right?) but this is good enough. You can install a second one to increase pressure even further, which would still be cheaper and easier than the alternatives but 1 works well enough for me.

I am using this pump for hot water taps in my home (cold water is coming from the mains and showers have their own 3 BAR pump, so only hot tap water pressure was an issue). The result is amazing, and beyond my expectation. The bathroom taps now have an excellent stream of water versus the useless drizzle prior to pump installation. I had a plumber install it as he was here refurbing my bathroom anyway and th pump itself was installed in 10 mins. Some additional time was needed to install a plug in my airing cupboard so we could plug it in, but the whole thing was done and installed in 45 mins. The pump is very quiet, it’s in my airing cupboard and is of course much quieter than the shower pump. all on all i’m very pleased and hoping this product will last.

we have used this to enable use of a standard bar shower in a room where we do not have sufficient pressure from gravity alone and one where the use of an electric shower was impractical. It it is effective from an adjustable hand held shower head on a riser or from an over head shower rose. Overall we get a warm shower but its not a silver bullet it boosts what gravity fed water you have but its not a miracle cure. reasonably quiet in operation but not silent.

I had a new kitchen fitted, and for some reason the hot water pressure at the new kitchen tap was very low. I bought this as an easy solution, and it works great. Easy to install in line with the hot water tap feed under the sink, and I now have twice the hot water flow. It does make a little bit of noise, but is barely noticeable over the sound of the flowing water from the tap. It takes around a second to kick in automatically, but once running the flow is much better.The one downside is that you need a nearby electrical supply, but if you have a dishwasher (as I do) then you probably have one near to the sink.

Positive- Easy to installNegative- Very noise when pumping ..- not as much increase of pressure as I was led to believe- for what it potential is sold on way to expensive.

Suffered from an extremely weak gravity fed shower system. Looked around at existing pumps which were horrendously expensive and require specialist knowledge to install. Then came across this amazing product online and felt it was worth taking a chance after seeing an example of it in use online. I'm so glad I did!! Not only do I now have a wonderful shower with good flow and pressure. I also have a reasonably quiet, cheap and easy to fit ( with some basic DIY know ) pump instead of a noisy and huge expensive pump. I cannot express how much of a difference this has made to my shower ! The communication is brilliant from the inventor and the company and the product is well packaged, superior quality and arrived quick. You will not regret purchasing this as it is so flexible. In the video I have attached you can see this is a perfectly good shower pressure now compared to my dribble of a shower before. Definitely a must buy!

I bought this item because living in a bungalow the shower pressure was dismal because of the low tank height. The unit was easy to install and wire in as it only needs a low output power supply. It did increase the flow rate slightly, just enough to make the shower usable, but nowhere near as much as I expected. It was also quite noisy from the start, but I dont have anything to compare it to. Unfortunately now, after 18 months it is failing to start and is even louder when it does start... I will now have to do what I should have done from the start and fit a proper booster pump. If this had been a cheap option I could have perhaps accepted it, but at the price it doesnt seem worth the trouble for 18 months use - buy a proper booster pump and have done with it....

I have a hot water cylinder and the shower takes its feeds from the cylinder and the cold water tank in my loft (which also feeds into the hot water cylinder). It took a bit of planning to work out where to fit the pumps (my feeds went via the loft, so that's where I put the pumps), and about an hour to cut the pipes and fit the pump. I wired a fused spurred socket into the lighting circuit, and the plug had a fuse built in.I would say you need a fair amount of DIY knowledge to understand how to isolate your plumbing (and electric if you're not just plugging into an existing socket).The fitted the "SP22S", which is one pump on hot and cold, purchased from their website with the extra warranty for £10. It made a big difference to the shower, going from barely usable, to a modest shower (still not as good as you'd expect from a modern combi-boiler shower if you have good water pressure - but much better than it was).
