re pressurizing the hydronic system

[bloomingtonmike]

I cleaned out the waste trap in my sealed hydronic panel. I want to make the pressure correct again. Is the correct process to do the same fill steps as I originally filled it ,and then close the outlet and let it pressurize to 15psi again with the transfer pump?

Ayuh,... Don't ya have an auto-fill valve in the system,..??

If not,... Ya pump it up, bleed it, then repump it up,...

I have a sealed system in a shop with no water. No autofill system. I grabbed a gallon and a half of the glycol mix, the pump, a container, and the hoses and ran it. Figured a good thing to flush out the boiler even though its only a 1 year old setup. Then I pressurized it correctly. Pretty easy really.

My autofeeder takes care of that for me.

As long as the system is down, I think it would be a good idea to check the Manuf specs on the system and use your transfer system to use an approved system cleaner prior to recharging. I was with a fellow who flushed his system with water and ended up with a problem with the boiler. I went with him to flush the system and boiler with the correct cleaner and you could not believe the **** that came out of the system.

Jack I think your system is much nicer than mine My Manuf is me. Ill hit up my boiler manual and read the services info on it.

This is why you should check the chemistry of the system and treat it if necessary. Flush and filling a system yearly is not a good idea more so if you are not treating the water.
