Hi Kevin

First revisit your sums and/or typing skills.

80 psi times 2 = 160.

Other than that I regret I have no useful information to offer.

I would suggest taking to 50psi, rest for 10 mins, if no pressure drop then up to 80, rest for 5 mins, if no pressure drop then increase in 30psi increments check for drops until you reach max pressure.

Others will probably differ

Roger

typos!

Don't go over 160 !

You should really try 15psi of air first just in case there's a seam not done.

I made a fitting to fit to a bike pump to put a LOW pressure of air in. If you can't get it to hold low pressure air don't waste your time with hydraulic. If it holds low pressure don't be tempted to go for high pressure air, go for the hydraulic

Good luck with your hydraulic. For those of us about to or actually building a boiler anything you have learnt along the way that would be useful to share?
