ECO TEC PRO 28

[DARTHVADER]

Hello.

I have a leaking pump on a an Vaillant eco tec pro 28.

Can anyone advise if the radiator flow and return pipes can be isolated at the boiler. The valves on the ends, I say valves because that's what they look like, but there doesn't appear to be any where that the can be actually turned off. I have isolated the cold water in and the hot out, but dont think this will make a difference as the leak in coming from the pump housing.

I'm not having the pump changed until next Friday and i just want to stop it leaking (its in the loft) and I'm fed up emptying containers.

Thanks.

You can isolate boiler heating circuit with 4 mm allen keys in the valves under boiler on left and right.

Or just drain a few litres from heating system.

Thanks Tony.

I thought there appeared to something inside the threaded protrusions on the valves.
