Shower pump

[Need Help21]

People,

Can anyone suggest a Company that can supply a 3 bar pump that can be fitted at the same height (or slightly higher) as the cold water tank.

I am unable to fit a pump under the bath or in the airing cupboard so the loft seems to be the next best place.

Stuart Turner are unable to supply a pump that can do this. They have advised I would have to raise the cold water tank.

The pump needs to be hot and cold input and hot and cold output to feed a shower only.

Cheers

your not going to get a shower pump that sits higher than its supply.

the pump needs to be lower than the supply tank

thats the long and short of it is it?

You need to be asking them for a Negative Head pump.

As far as I can see they do them.

Failing that look at Salamander or Watermill.

But speak to Turners first asking to Neg Head pumps.

why can't you put the pump in the loft and raise the cws tank ?

Thanks Seco, That is probably what I am going to have to do.

Stuart Turner have advised that the top of the pump can be no less than 500mm from the water line in the cold water tank so I am hoping it won't be a major job to raise the tank

Moving the water tank in the loft will not be an easy job. Its present position, with regard to its capacity, is probably as high as the plumber could fit it when it was first installed. Bearing in mind that you are fitting a pump, you need a big tank. If its laid on the joists, its because the weight has to be spread. If you put it on a 4 legged table secured directly to the joists, the 4 legs will stress the joists. So, I would advise a solid platform (25mm ply) to spread the load and build the table on that, with the legs located on the spans between the joists.

If it is at all possible, could you fit the pump below the floorboards in your bathroom? It should be adequately cooled by inter-floor ventilation and also prevented from freezing, which is another issue with pumps in lofts: keeping them cool (ie no insulation should be wrapped around them), but also preventing them from freezing in winter.

Either way, you have some hard work ahead. Good luck.
