Air in my 8 Station Sprinkler system
I have 8 Weathermatic Silver Bullet Valves.
I have 8 stations in my sprinkler system. Never had any thumping until I had to turn house water off recently.
Now when the sprinkler system is turned on severe thumping in my house.
I had to turn sprinklers off this morning because thumping is so loud bothersome.
So I tried what the web suggested I removed sprinkler heads from station 1,2,3 and ran water through those stations for about 5 minutes or so. Shut off the stations and attached sprinkler heads, and tried to water, no luck, still thumping.
I manually opened all 8 valves and let them run for a while to remove air, still thumping.
This is driving my nuts. How do I fix this??????
When I need to turn the house water off I can not have the sprinkler system thumping.
The sprinkler system is on it's own dedicated hard water line bypassing the house water.
The house water line splits, one to the house through the water softener, and then the hard water to the sprinkler system.
The hard water line has two outside faucets.
I opened those up and did get some air removed.
The sprinkler system line also has a on/off ball valve that allows me to turn water off to all the sprinklers.
This driving me nuts. How do I fix this so it goes away and stays away.
How do I get air out of system and stop this thumping and stop it from happening again.
Any help is greatly appreciated.
I have spent a lot of time trying to fix this.
Thank you
