plumbing question regarding mains water pressure

[gizmopb1]

read the warranty on my new ($$) mixer taps

says warranty void if mains water pressure >500kpa

live in a 30 year old house

questions

1.
is it worthwhile checking the mains pressure and fit a pressure limiting valve?

2.
if i limit the pressure, how will the upstairs water pressure be affected

3.
how much do you think it will cost to get a plumber to fit a pressure limiting valve?


thanks.

No ignor it, the seals will eventually go like on most working parts, and worrie about more important things .

Hi gizmopb1

1 absolutely, Melbourne generally has a rating around 900KPA.

2 no discernable effect.

3 possibly $150 to $250.


Ignore it at your at your own peril,the seals may or may not go and the tap may leak into
the fixture, possibly not a big deal.

Alternatively the hot and cold flexible connections(which are rated to suit the tap) under the fixture could burst flooding the property,the supplier and your insurance company can obviously then deny your claim.

Seen this happen more than once and as a plumber would refuse to fit this tapware without a PLV as liability would fall onto me.


Have argued with more than one builder over this as they don,t want to pay the few hundred $$$s required to meet the plumbing regulations.
