Question 1

I have low mains water pressure which affects 2 showers in the house. What can you suggest.

Accepted Answer

We have two showers. The hot water is gravity fed and the cold water is taken from the loft tank to equalise the pressure in the shower. I dont know how the previous owners coped with the pathetic shower pressure. So I fitted two of these in the airing cupboard. One in the hot out from immersion tank (heated by by gas boiler) and one in the cold out from the loft tank. They work very well but it's best if you only have one shower in use at a time. Also if someone opens a hot water tap in a basin or kitchen then the pressure drops, but we are a small household so it's ok. The plus side of this setup is when someone opens the cold tap to water the plants or something, there is no drop in pressure as the water is coming from the loft tank ( which as a complete aside I upgraded to a byelaw 30 one.. much nicer not having bee brains and spider body floating in there.)

I'll try get round to writing a full review. In summary I am happy with these. They are not the cheapest, but they are EASY to fit and the 12V means I could do it myself. I originally fitted one pump only in the hot water feed as suggested, but the shower pulsed as the shower mixer bar tried to balance the temperature. I then fitted another one in the cold feed but due to the hot/cold ratio in the shower I had to connect the cold pump to run when the hot  pump is triggered. I bought a y-cable to do that.

Our setup is not perfect. I need to fit a timer to switch off the power to the pumps, otherwise they come on when someone opens a tap in the kitchen for example. This is annoying as the cold pump runs when only the hot is opened so the pump cavitates which doesnt sound great. I plan to fit that to the power strip feeding the AC/DC power supply for the pump. It would be nicer to hook it up to the shower extractor fan, but that means an electrician.

So.. this setup isnt the cheapest but it works and I could do it myself. I am happy with it, but will be happier when I put the timer in. I didnt need to get a plumber or electrican round, so that saved a few quid.

Hope that helps and I'll try write a proper review. I have had them for about 6 weeks now and they work great. Had I known about the cold pump needing to be manual in our setup I could have saved some money buying a manual one to slave off the hot automatic pump, but its done now and I dont want to take it out.

Question 2

Hi, can someone explain what the fundamental differences (or pros/cons) of this product are compared to a pump like the Salamander? Thanks

Accepted Answer

There are several differences between SPB & other pumps. The SPB is an In Line Pump and is suitable for all plumbing systems. Please contact our technical team SPB@flowflex.com for further information

Question 3

Is this pump self priming?

Accepted Answer

Yep it's litterally plug plump and go, when you turn the tap on it auto turns the pump on. Short delay in it picking up the water flow but we are talking only seconds.

Question 4

Can this be used with pladtic pipe and fittings

Accepted Answer

Yes, can be used with 15mm and 22mm plastic pipe as long as you use stiffeners inside plastic pipe.
