Ideas for fill loop location?!

[roofie71]

Hi, We‘be recently moved into a property with a very old Potterton statesman. My husband bled the radiators last night…and since then he’s called all sorts of problems! There is now only one tiny radiator with heat in it. There is no pressure gauge on the boiler , I can’t find a full loop on boiler. And I’ve looked on the downstairs immersion water cylinder to see if there’s a fill loop there as some one had suggested this . How can I get pressure into the system? Can you suggest any other places we could try looking …we haven’t been up in loft yet to check if anything on the other water tank up there, is that likely? Many thanks in advance for any help you can offer. It has a Grundfos selectric, which appears to have valves above and below it. Ruth

Check the loft for 2 tanks ,one small one would be the feed for boiler / central heating. The large one feeds the domestic hot water cylinder.
The small ( F&E) tank should have 4 / 5 inches of water in ,it doesn't need to be full

If you have two tanks in the loft, that would be a conventional setup so you won’t have a filler loop. If the small tank doesn't have any water in it it might be the float stuck. If there is water in it, it might be airlocked, When we had a system like that, it was often difficult to bleed after it had been emptied. A plumber showed me a trick once and I used it several times after. That was to get a 2ft length of garden hose, push one end into the feed hole at the bottom of the small tank, give it one long hard blow to force water downwards and then quickly remove the pipe. The airlock would then be cleared and water would flow down it.

Could also be a blocked cold feed?
