 Daily morning air lock expulsion in hot water system
Author: peter m (Canada)

I have a new 50gal hybrid hwt. The first use of the hot water in the day delivers a normal flow until the existing water in the lines is flushed through,(still cold) then as the hotter water starts to flow there are burps of high pressure somewhat steamy air pockets that last for 10-15 seconds. This new tank was put in a new position out in the carport. This is 3/4in copper supply line which comes though the wall and drops down two feet to connect to the tank leak detector shut-off valve inlet. Three 90deg and two 45deg used in this process. There are four modes of operation. I use energy saver mode, and also electric mode with no difference. This is our well water with a 60/40psi switch. I am a long retired auto mechanic. Very much enjoyed problem solving. I am more than somewhat stumped. Ha!
Thank-you
Peter M

Awhile back this problem occurred because of a fault in the anode rod manufacturing
Try changing the anode rod
