New waterpoint tap?

[Chappo]

Have CRT changed the tap fittings...thus thing is useless..sprays out the 4 holes. What is it.

Where have you been? Been in use for years, also now on the Thames. Read recently that also used in the River Nene so only a matter of time before the EA fit them here on the Great Ouse.

There's this thread from a couple of years ago which looks like the same device

It is intended to prevent water flowing back through the tap from the 'user' side, which may (perhaps) be unclean. If the device detects that the pressure on the tap side exceeds a set level it discharges the supply through the side holes. The use of them follows on from some fairly draconian rule making regarding what you can attach to a water company's supply. At least they avoided the attempt to ban all hosepipes as seemed to be on the cards at one point, I believe.

 

If the device you used was in working order then you need to see what in your hose is causing the pressure build up - perhaps you have your own valve on the end? Or the hose was twisted?

 

In my experience they generally work as intended but I have come across  a few that trigger at an unrealistically low level.

CRT use these in sani stations for flushing out porta potty tanks on idea where that one was laying on the ground.

[Chappo]

It was laid out in bits on the side. With no tap fitted to the water point. I obviously don't travel much..especially down south. Thank you for input

On the Thames I have seen several wrapped with tape to allow use at higher than intended flow rates.

Was it by an Elsan point?

[Chappo]

I've already got a jubilee clip / innertube combo ready to go on to speed it up.

It was a water point. Elsan is twenty yards away.
