CA VALVE ISSUE?

Hello

I'm having an issue with a Gulfstream A-Class boiler.

Please forgive my lack of technological explanation...I don't know anything about boilers!! My issue, as i see it, is that water is constantly running into the tundish, splashing out and leaking. My understanding is that the CA Valve may have failed alowing the water through. My question is, if I use the tap to stop the CAautofilling device is this likely to cause further problems until I can arrange for an engineer to look at the boiler?

Any advice will be very welcome
Thankyou

Hi;
I do not touch or know much about the Gulfstream.
Your unit is discharging and really needs checking.
What is the pressure?

Hello Mike

Thanks for taking the time to reply

The pressure is stable at 1 bar (it's always been at 1). I'm limiting the time the boiler is running until the engineer visits, this will be on Tuesday. I'm constantly checking for pressure drops whilst the boiler is running, but it seems to be stable. I don't like moving the taps on the autofill system but it seems to be providing a solution at the moment
