Kitchen Tap low water pressure

[AndyRoo]

Hi there, I've recently installed a franke sink & pilatus tap which has a spray attachment. The problem I have is that the hot water supply (which is gravity fed) doesn't have sufficient pressure.
From what I can gather I need to install a booster pump to rectify the situation. What I would like from this forum is a bit of advice over which pump to use. I'm sure I've seen a central heating pump used once before and would be interested in any comments/instructions that you may have.

Thanks in advance

Just using my own logic, Central heating pumps are designed primarily to recirculate water in a closed system with corrosion inhibitors etc.. I don't know how one would fare in the situation you describe. It would be constantly exposed to fresh water, complete with it's loading of limescale and corrosive elements.

If it failed in a rather a short time, (I'm not saying that it would), it could be argued that, the waranty would not apply, as it is not being used for it's prescribed purpous. I'd err on the safe side and pick a unit that is specified as a booster pump. The designers of these units would have specified materials less likely to become furred up or corroded.

It may be that central heating pump manufacturers do, indeed, specify the same standards in their pumps. I don't know, I'm just guessing really.

how about, no pump. it is not allowed to pump mains water (so i read on these forums)

I might be wrong breezer so bear with me

I think you only want to boost your hot water (gravity feed) system?

if this is the case then you need a single impeller positive head pump (anywhere from 150 to 400 depending on which make)

A central heating pump WILL NOT DO

Please note that Central Hetaing Pumps should be refered to as CIRCULATORS as they move the water about and will not produce enough force to boost a supply

I do agree with what you have said corgiman, but what sort of shower does Andy have at the moment? If he only has a gravity or electric one, he should consider fitting a twin impeller pump because it would give him the opportunity to have a proper shower.

He just said about his ktichen tap mate

 

[murraysnudge]

I know he did, but I'm thinking ahead. If he's going to the expense of fitting a pump he has the chance to fit a twin impeller one & pump all the hot and cold water.

Thankyou to everyone who has taken the time to reply to my questions, they have been very informative and useful. From your comments I certainly won't be using a central heating"Circulator pump". If I may be so cheeky as to ask for recommendations upon what make/pressure single impeller positive head pump I should go for.
Thanks again everyone, and look forward to hearing what this weekends little project is going to consist of.
cheers
