Mains pressure shower booster pumps
 

Hi

I consider myself a relativly competent DIYer, and have a clean basic
looking shower, but the pressure is irritatimgly low. I'd loath to buy
one of those wall mounted power showers (anyway my wife would never
allow it) so i went to B&Q to buy a pump to put in line under the
bath... Once I got home i discovered it was not for use with mains
pressure water...

I have two questions really, what is likely to be the consequences of
using this 2 bar pump... and if they are likely to be dire, is there
such a thing as a pump that can handle mains pressure?

any guidance or advice is welcome

Thanks

Charlie

You can't put a pump on amains supply. You have to take it off a tank or
cylinder. Ever through of having the mains uprated from street? A lot
cheaper than an expensive pump and all problems solved

Unless your door opens right onto the street its going to cost more
than a pump!

Not necessarily a full destruction of the drive. When my Dad's supply was
replaced. the water company dug 2 holes (one in the pavement around the
stopcock) and used a "mole" for the bit in between to make a hole through
which they shoved the pipe.

OK, still some destruction, but not as much effort to repair as a full
trench.

How much did it cost? and how far can the "mole" bore between holes?

Sorry - don't know. Done by the water company some years ago for my Dad.

and how far can the "mole" bore between holes?

In this case, about 6-7 metres. I have no idea what the upper limit is.

You can't use a pump on the mains.

The cheapest new supply will be more expensive than the most expensive pump.

Not that it helps, as it is illegal to pump mains water.

Christian.

Ok, so in sumary it is illegal to pump from the mains... But then i
have to ask, should I still be using a pressure washer?? still the
point is moot...

I dont think the water supply being replaced is really an option,
sounds a bit of a nightmare... anyway the house is only 5 years old...
so what could possibly need replacing...

I think i will get a single sided pump and just boost the hot....

although i am intrigued, is pumping the mains just illegal, of does it
have physical consequences too?

Thanks to all

Pressure washers do (or should) cut out when the input pressure drops too
far (mine certainly does)

Yes. All water mains leak somewhere by small amounts. This is not a problem
as they are always under positive pressure and clean water is always flowing
out through the leaks. If someone puts a pump on the incoming main, there is
the disnct possibility of getting negative pressure (ie below that in the
pipe's surroundings) in the pipe. At this point contaminants will be drawn
in through the leaks, contaminating your (and other people's) drinking
water.

It is illegal, very antisocial and possibly dangerous.
