Guys I been looking at buying a American-Style Fridge Freezer that needs to be plumbed for the ice & water dispenser..
But the manuals recommend a water pressure of around 22psi to 100psi and I think the water pressure from my mavity Fed loft Water tank would only be around 10psi . (if 0.43psi per foot of height is correct).
And the main water feed into the house is also very low pressure..


Does anyone know if this would cause problems and could anyone recommend me a small on demand booster pump ?

If you're drinking the water wouldn't it be much better to plumb it into the mains rather than the loft storage tank. There are way too many stories of dead animals being found in loft tanks for me to be comfortable about drinking regularly from them (I've personally found a dead bird in ours, as well as rotting wood from the cover...)
 
Can't help with the pump but it could also be worth considering one that doesn't need plumbing in, I know LG do them. They use a tank about the size of a large Brita jug that fits into the door.

I might be wrong but I thought all the taps in my house are fed by are loft tank...

You now scaring me and am off to check for any dead or alive creatures in my loft tank and try to work out what all the pipes from the tank feed to ..:( :D

Haha, I have to say I had a google before I posted to see if there was a recommendation for whether to drink regularly from the Loft Tank taps and one of the recommendations I saw was to turn off the mains stop ****. If the tap still works it's from the loft, if it doesn't its probably from the mains.

It's definitely worth checking the lid of the tank. We rent currently and the lid was just a thin bit of dusty hardboard that had sagged into the tank because (I assume) of the moisture... We only found that out when the overflow started flowing outside the house but the condition of the board suggested it had been in the water for a long time. Probably not going to kill you but not really something I'd want to drink from for long periods of time! :p

I looked at them but they only hold about 3.5ltr of water and I know it be always left to me to keep it filled up all the time while everyone else uses it..:(

Plus the fridge am really interested in they do as a plumbed in version only..

If you want ice and water on tap then plumb it in.

The non plumbed in ones are just a PITA.

Downstairs is highly unlikely to be anything other than rising main.

I replumbed my house so that the toilet and taps upstairs both come from the mains.
 
The downstairs kitchen cold tap is unlikely to be tank fed, also there's a minimum pressure that water company's should provide. Surely if its mains fed it should be sufficient?
Mine is mains fed but the first thing it hits is a reducer, the actual pipe into the fridge is only 8mm iirc. On tap filtered water and endless crushed or whole ice ftw :)
 
I've never heard of cold water taps being plumbed from a loft tank, always fresh direct from the mains, including bathroom and toilet.

Certainly never anywhere I've been.

Yuck.
 
Your kitchen tap will be fed direct from the incoming water supply while the rest of the cold taps are fed from the tank in the loft. You should be using the kitchen tap for drinking water and bathroom taps for washing only.

It depends actually, there is a huge variety of plumbing systems. Lots of houses are all mains, lots are loft fed for upstairs.

Nothing except the shower in my house is fed from the loft tank.
 
It's rarer to see peoples cold water fed by a tank nowadays, as mains pressure is pretty good, and there are much safer ways of boosting if it isn't. But there are still plenty of these tank systems around, but even so regs required the kitchen sink to be potable, mains fed. So any water needed for drinking should come from this and not a tank, even if the tank is fitted with a bylaw 30 kit.
If it was a concern then get a plumber in to assess your system type and measure your water pressure. If he's any good then he will advise on the best setup for you, health and performance, and whether the water authority need to come out and look at the pressure.

wow i never knew any cold water taps were tank fed, urgghhh nasty thought. I assumed the tanks were only for only hot water systems

I measured are mains water pressure today and it was just over 1 bar (about 16psi to 18psi) :(

If that's a correct reading then I'd be on the phone to your water supplier. I think around here Severn Trent are required to provide 2 bar minimum, it might be similar for you.
