Re-pressurise boiler

cjm8888

Hi,

I have a leaking bathroom radiator that I want to fix. Afterwards i will need to re-pressurise the boiler its a Glow-worm 25r. Looking online I dont see the two valves needed to do this.

I have a Magnetic cleaner above the boiler with what looks like two valves, would these be the valves needed to re-pressurise the boiler ? Picture below.

Thanks in advance.

Sadly, no - these valves are just to isolate the filter for when you unscrew it to check the contents (which I hope someone does every 6 months to a year?).

Best you post a photo of the underside plumbing of your boiler, and we should be able to ID how the top-up is done. I presume your boiler has a pressure gauge on it?

On a different issue - what's that white scale all over your filter? Are you in a hard water area? Has that white stuff come from a  leak around there?

From a first look at the installation instructions, it would appear that - if yours is a sealed system (has a pressure gauge) - then it's topped-up via a flexi hose and two valves. Can you see that anywhere? If no flexi, are there two open-ended valves under the boiler?

If you don't have a pressure gauge, then are you sure there isn't a wee F&E tank in t'loft? So it'll top-up automatically...

Thanks,  We do have a tank in loft. So does that mean the system will self pressurise and I dont need to worry about it ?

With reference to the white stuff. We do live in a hard water area. The next service i was going to ask about that. I have checked the area and its very dry and I cant see any evidence of further leaking.

If it's a small F&E tank, yes.
DOES YOUR BOILER HAVE A PRESSURE GAUGE?!
As far as I understand, these boilers can be fitted to either gravity or pressurised/unvented systems. Only the latter will have a pressure reading, and will need topping up. The gravity type self-fills.
I have to say, tho', in a hard water area in particular, I'd much rather have a sealed system - far less water quantity involved, and therefore less scale. Not sure it's worth converting, tho'.
