Hello all. Might be a daft query but the overflow that was originally fitted to our kaldewei bath has never been secure and always comes loose as the bezel inside the bath simply comes unscrewed. May I ask - have I got the wrong overflow, or has it just been badly fitted? The reason I ask...

Fear you may be right about the heating circuit, but definitely going to give this a go first. I made up the injector tee I installed in a very similar way to what you describe. It works a treat. This looks like the valve you're talking about...

The system is very similar to the schematic on the Rayburn site you mentioned initially, but I reckon the pipework on the DHW loop and the CH loop are poorly matched to work together. To give you an idea of what we're up against, the bloke who initially 'installed' the system had a second...

[/url] No - it's not really that kind of system. Though I have had a good read-through of all that stuff and it's very enlightening.

Our set-up's broadly similar to that shown in the diagram. I get the idea behind the injector tee, and since I fitted one, the DHW loop works well when the pump is operating, as well as by convection when it's not. And as I understand it, it's when the pump is operating that the injector tee...

Thanks for that - very useful. And I guess I can easily test whether I've got sufficient head by simply temporarily capping the feed to the cylinder. Solved. Cheers.

Thanks Norcon. Yes, I've looked at that diagram quite a few times myself! I just wonder what might happen at the tee just above the high-limit stat on that diagram when the zone valve on the cylinder branch pipe is closed. If the back-pressure from the CH loop is very high, might the pump...

Hello - hope someone can help me with this query... Bought an older house that came with a solid-fuel Rayburn as the heat source. The boiler only has two tappings, but there is a gravity DHW loop and a pumped CH loop. When we first arrived, there was no injector tee on the system so when...
