Flexi Filling Loop Burst

[richdeniro]

Hi All,

Today was sat at home and heard a pop from the kitchen, went in there and had water gushing everywhere from a burst on the flexible hose thing that connects the water supply to the boiler via the filling loop.

Managed to turn off the water at the mains after a couple of minutes as Thames have just fitted a water meter so for some reason I now have two stopcocks, one above the meter and one below (should they have installed it this way?). The damage wasn't too bad but a fair bit leaked down to the flat below.

I bought a new flexi and fitted it myself, turned the water back on and everything seems ok but am now really paranoid that it might happen again and it would be a disaster - I've never seen so much water from a 2 minute leak and if it happened when I'd been out no one might have gotten to it for hours.

Have been googling and came across something called a 'Flood Stop Isolating Valve' and wondered if anyone knew if something like this would stop any future leak if the flexi hose failed again? Also would it be something I could install myself or should I pay to have a plumber install it and how much would that cost?

Cheers,

Rich.

Just leave the valves off and disconnect the flexi and when you need to top up reconnect it

Could the valve be broken, if I remove it I fear water will start coming out again?

Have you replaced the hose, and both valves. Or just the hose?

You replaced the valves ????

 

[richdeniro]

No just replaced the hose

 

[ShaunCorbs]

I would say the valves need to be replaced

There only seems to be one valve at the bottom, if I turn it clockwise the pressure guage increases. Also the pipe that it feeds into on the bottom right (labelled as 'CH return') has hot water flowing through (whilst the heating is on) it now when this is where the cold water was coming from when the leak happened and it stopped when I turned the water off at the mains.

Hi
Both ends need replacing. The non return valve at the top is better with an isolation valve too.

Then always make sure both are turned off after filling.

Just looked at your pic again.

The valves are fitted in the wrong order . This means that your flexi hose is always under full mains pressure!

Thanks for your help, that's the way they were on there.

I'm going to call out a plumber tomorrow to do it properly.

The top valve is the water inlet.

The top valve is the water inlet.

Correct.
That valve should have been fitted on the other end and vice versa

Thanks for your help, will definitely book a plumber.
