Pressure reducing valve for outside tap?

Accomodation, House and Garden

Has anyone seen bought a pressure reducing valve for outside tap recently?

If so, from where?

Our mains water pressure is incredibly high and if you use a hose pipe and don't turn it off at the tap, in a short while, the pressure will split the hose pipe

Ideally it needs to be metal and to be able to screw onto an outside tap (thread 3/4").

I've seen a few plastic ones.

Thanks!

I think my husband got ours from Landi. They have a lot of metal things there that you can't find elsewhere apparently.

Thanks, I forgot about Landi. A lot of their stuff is for farming use so is pretty heavy duty.

Surely you should have a pressure reducer on the inlet pipe to the house or do you have 2 inlets ?

We have a sodding great reducer on the inlet pipe as it comes in, the pressure is reduced before being distributed around the various outlets, including the outside taps.

Maybe your supplier should be able to assist, even install at their cost ?

Go to a DIY (Hornbach) and get one, i know they sell them their, if i 'm not mistaken, when i changed mine it was about Chf 300.-- including fitting by the local plumber (cash only....)

On older houses it is quite common to have the garden hose fittings at street pressure, and the inside behind a reducer.

Street pressure is sometimes nice to have, saves you getting out the pressure washer for washing your bike, or filling a pond/pool.

The plastic reducers are generally crap.

@Tom: You can get a metal reducer at plumbing supply places, and at Landi. Fit it on the inside of the building if at all possible, otherwise you may have frost problems. I would also fit a bypass valve so you can have street pressure if you want it.

We have one inlet and a pressure reducer in the cellar. However, two of the outside taps are fed directly from the mains (before the pressure reducer).

It would take ages to refill the pool otherwise.

I just want an inline one so I can have it on most of the time but remove it for the winter or when more pressure is needed.

The garage has it's own pipe so that can stay at mains pressure.

I'm not doubting you in any way but as a question of interest, how do they invoice your water usage if it comes directly from the mains ?

Do the outside taps get fed after the meter but before your inside pressure reducer ? Seems strange way to do things, normally i would expect to see inlet pipe, pressure reducer, meter, distribution.

In our house it was Feed>meter>Branch T (to garden)>reducer>internal distribution.

I didn't mention the meter as I thought it was obvious that there was one on the mains inlet.

Main inlet - meter - T-piece (one branch to outside taps, one to pressure valve/filter - water softener - taps and appliances).

My brain is usually a bit dulled on Sundays, today is no exception...

I was going to suggest you mill yourself one from metal, but then realised it was the wrong tom

13
That's exactly the arrangement we have.

14
A lathe would be better.

15
A lathe and a mill would be even better.

(and a surface grinder, and a press, and a foundry, and a...)

16
.....and a qualified plumber would still do it for far less, even an expensive Swiss one !

17
Something makes me suspect that none of your toolboxes have wheels...

Landi didn't have (at least my Landi didn't) and Hornbach only had a Gardena one, in plastic, designed for drip systems.

I bought one as I have a time clock valve for watering pots when we are away but the Gardena one really is designed to sit on the floor and be connected with a short length of hosepipe.

I suppose I could use a 3/4" - 3/4" coupling instead of a hose and have the pressure valve hanging off the tap and the time switch valve after that.

But, I'd still like to get a metal pressure reducing valve that can fit on a tap so if anyone has seen one and/or has a link or brand/model number -I'd appreciate it.

Yes, I suppose I could fit one inside the house with a bypass valve so I'm looking into that too.

You could get this to work or get this one a bit cheaper from amazon.de.

If you don't mind 2nd hand you could check anibis, tutti, ricardo, some offers there actually include a manometer and seem fairly inexpensive. But you'll need to make sure they are fit for "your" pressure so no links from me.
