AquaHot.. had zone pumps replaced and now..

April 30, 2019, 02:16:49 am

Had Premier in Junction City, OR replace the pumps and check valves due to "dribble" leakage.
Now I noticed that the overflow bottle fluid level is not filling/emptying nearly as much as before.
Not cold enough to really tell if the registers are getting as hot as they should..
Nearly new radiator cap.
Stuck pump (needing a "tap") or air bubble somewhere?

ANY suggestions are welcome.....

When it has cooled off, Open the cap on the top of the AH and check coolant level.  You should be able to feel it with your finger.  If not full add appropriate coolant.

I could be wrong, But I bet the shop just forgot to top up properly. Rogers plans sounds like the best first step. Then monitor the level in the expansion tank till you are satisfied that it's stabilized.

Hope it's a simple fix.
