This may seem like a really stupid question but my pressure has gone down to 0 & I need to refill it to between 1 & 1.5 but I cant remember how you do it!!! Can somebody help please?
Many Thanks
help. i have a vaillant vcw 18 sine t3w combi boiler.
The water pressure has fallen to almost 0. I need to refill.
I cannot find the cold water refill valve!!! i have searched the manual (a useless diagram), and I have checked this site FAQs and stickies. I am none the wiser.
Please could someone post a reply that tells me exactly where this valve is (apparently somewhere under the boiler according to the manual diagram). with a proper diagram or photo. please please please - don't want to spend £50 on a plumber to open and close a valve.
i only had to rip a hole in some boarding near the boiler and search around in the dark for a couple of hours until i found the flexible hose and the valve taps at both ends.
Vaillant boiler almost 20 years old. When central heating is turned on, during the cycle, it keeps switching off and on at regular intervals. We called a corgi engineer but seems he has not managed to solve the problem and would appreciate suggestions as to what could be causing this problem.
