Hydronics systems, seats and springs, drain cleaning
Tool Tips—February 2014
This particular trick was used in my home where I was upgrading my hydronic baseboard to PEX radiant. With the PEX already installed, I was to remove the old baseboard and piping by using a high capacity wet/dry vac to suck the zones dry and free of water.
I simply isolated the zone, allowed it to cool, drained the loop by purge valve, and placed the vacuum on the drain. Let it run; you can hear the water in the pipes and see the vacuum hose shake as the water is removed from the system. You can then introduce air at bleeders or other mechanical openings. It makes a dry, easy and mess-free cleanup.
