filling loop
In Riemannian geometry, the filling radius of a Riemannian manifold X is a metric invariant of X. It was originally introduced in 1983 by Mikhail Gromov, who used it to prove his systolic inequality for essential manifolds, vastly generalizing Loewner's torus inequality and Pu's inequality for the real projective plane, and creating systolic geometry in its modern form.
The filling radius of a simple loop C in the plane is defined as the largest radius, R > 0, of a circle that fits inside C:
So our filling loop only seems to allow water to flow when you open it for about 3-5 seconds and then nothing. Trying to top up boiler pressure as it's about 0.7 bar. If you wait 5 minutes you can open filling loop and you get another 3-5 seconds of water through it before nothing happens again...
Tried repressurising by turning valve on filling loop. Normally you hear water whoosh through. This time no water. Took lever off and turned with spanner then took loop off and tried again. Water is coming through so now thinking broken NRV, is there a way to fix them or could it be an issue...
I have a combi boiler with a leak. It has been leaking for years but the landlord has rarely gotten it serviced (last was 2 years ago). Anyway, because of this leak, we have to refill the boiler every day. The old filling loop has no taps, just screws, and, after 2 years of using a screwdriver...
Good morning all
Vaillant ecoTec Plus 831 Filling Loop
Can anyone recommend a pair of suitable end caps for the above?
An Amazon or eBay link would be good.
Thanks
Hi All,
I recently increased the pressure to the central heating using the built in filling loop. In doing so, I noticed there is water dripping from the bottom of the pipe that the filling loop is connected to ( the pipe that allows water to the enter the system). This also looks like it is...

Hello,
Please can anyone offer help with my Volkera Mynute HE. I have no pressure at all according the gauge and when opening the valves of the filling loop water has definitely gone into the boiler. The gauge does not show any increase in pressure and when removing the filling loop water is...
Afternoon all,
My boiler pressure is slowly rising above green every other week and I've located the leak to be the check valves on both sides of the filling loop. Is there anyway I can cap one side off untill I can buy a new part? Furlough has made it hard financially atm. I've included a...
I've got a potterton symptoms he 40 boiler... I'm planning on changing some of the radiators and will need to fill the system back up once I'm done but I can find the filling loop connected to the system. Not under the boiler or above. Also doesn't help that there is no pressure gauge on the...
Hi all and thanks so much in advance for any advice! My boiler’s pressure is below 0.5 but I can’t see where the filling loop might be. In the photo below I though perhaps I should attach one to what look like valves on the two identical pipes on the left, but these both carry hot water so I...
Hi All
I have a filling loop in one of my properties that has been left connected.
It also looks like the tenant has been filling the system and rounded off one side (CW) off the isolation valve one way valve.
It looks like it is in the open position but is not turnable (unless i dremel a...
Hi,
in what circumstances, would you say, it is ok to install a boiler without a filling loop and/or check valve?
We had a new boiler installed without a filling loop and/or check valve. I had conflicting advice on the subject: some say it is illegal not to have a check valve (risk of water...
I need to pressurise my Vaillant ecoTEC plus 618 Boiler, but can't find the filling loop!
It's not under the boiler itself... (IMG_1696.jpg)
And I'm uncertain about the pipes around the water tank upstairs (see pictures attached) -- can you see anything there?
Where do you think it could be?
I'm wondering if anyone knows of a mod that can be done to the above boiler to enable the boiler to be pressurised without having to use the key method which is a pain in the a##e
Thanks
Can anyone point me in the direction of a replacement filling loop assembly for an old Worcester 24cdi Boiler.
Part number on the broken filling loop is 8 716 141 062
GC no. G20 47 311 32
GC no. G31 47 311 33
As it’s an old boiler and in a static caravan a replacement boiler cost would be...
Hi All.
We've woken up this morning to zero hot water and my diagnosis is that the (Intergas HRE Compact SB) boiler needs to be repressurised. (It's only a year since install, so I'm a bit surprised but...)
We didn't have a lot of handover from the installer and, having taken a look, I'm...
Hello,
One of the black levers on my filling loop under the boiler has stopped working (when I turn it it's not opening the valve and no sound of water coming through). I think I just need to unscrew the black lever and fit a new one, but I can't seem to find one when I search online. I've...
Hi Guys,
Whats the best way to cap off a Vaillant plus which has the integral filling loop, I'm going to fit an external one, Would prefer to cap off the old one rather then pay for new valves and loop. Cheers in advance.
Hi all
I bled a radiator today and had to top up the pressure on my Glowworm 24cxi combi.
After I closed the valves and turned the heating back on there was a slight trickle of water from flow side of the loop. Couldn't see exactly - but not the valve itself, somewhere above it.
Just a few of...
Hi all Im a gsr and just after clarification into this,as genrally manufatures state to install on return pipe of boilers.
Im only asking for advise, as a senior gsr said to me that its best to install on the flow side as when flushing the system connecting to the filter, it helps filling water...
