Hello,

I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thank you!

Good evening, my name is ***** ***** I’ll help you today.

The first thing to do is establish whether or not the system can be pressurised. Do you know how to do this, or do you need guidance?

Good morning, I haven’t heard back from you.

The following video shows the process of increasing the pressure.  It’s not exactly the same process for all boilers, so let me know if you don’t succeed.
