Vaillant low pressure top up the system to 1 bar pressure

Although I said 1.5 bar for this system most systems require only 1 bar. If your boiler is loading pressure regularly contact a professional it’s cheaper to investigate a leak rather than filling it up constantly causing problems later on.

Thanks to this guy's video, I've just had the first hot high-pressured shower in a long while. Stayed in there almost twice as long enjoying it. I've also transferred £300 from my savings to my current account for solving the issue. Cheers, matey! 😁

What happens if you do this, the analog gauge goes up but the digital screen still says 0.0?

Hi we have the exact same boiler and its suddenly turned off. Is this due to the water pressure?

How to make pressure lower?
I have 3 bar and is flashing

What if water starts leaking out of the second valve?!

Help please my boiler has a key instead.

I did not do it quickly, so too much pressure no water comming, zero, what to do ?

I can only see 1 gold valve on my right side can’t see anything on the left??

[KellyMikaleson]

I used to do it myself but the council boiler man disconnected the silver pipe between them so I can’t do it making me have to constantly call them out

[freshfamilies]

None of these videos show a pipe set up like mine

Wouldn’t top up to 1.5 just do it to 1.1 when boilers cold don’t top up when it’s hot gives you a false reading as everything expanded.. don’t run your system at high pressure no point
