Fix for solar panel "steam hammer"

By Solar Home Owner

from Monument, Colorado

Verified Buyer

Comments about Watts 3/4" N 36-M1 Water Service Vacuum Relief Valve:

I used the vacuum breakers (one each) on two 4-panel solar hot water arrays located on a second-story rooftop to facilitate faster water drain-down.

Breakers effectively eliminated a steam bubble explosion from water flashing to steam at the top of the panels by allowing quicker drain back.

Bottom Line Yes, I would recommend this to a friend
