Dishwasher. Pressure reducing valve required?

corglass · 14-11-2014 01:44PM #1

Hi guys,

I'm installing a dishwasher in my kitchen and propose to use the cold kitchen tap supply as the feed.
There is no other cold water supply nearby.

I remember hearing that domestic water pressure may be too high and a pressure reducing valve would be required?

The dishwasher water pipe has a block (see attached) on the end of it with a power supply from the dishwasher going to it. The block has a 3/4" brass connection and is labelled Max P 10bar, 60 degree C.

This seems to suggest I can just connect it up as there's no way my incoming supply is even a quarter that pressure.

Any thoughts or help appreciated.

Thanks

Ten bar is equivalent to 150 pounds per square inch, and I would guess that the machine manufacturers are protecting themselves from claims of failures where pumped water supplies are involved. If your mains supply ever reached that pressure your cold water tap would blow you out of your kitchen and there would be even more water mains bursting all over the country! Don't worry about it!

Water pressure in Ireland sits somewhere in between 1 bar (low) to around 5 bar (high). You have nothing to worry about.
