Trying to diagnose a large banging sound from my crawl space. Here are the variables:
- House is 1.5 years old
- All pipes have been secured
- Water arrestor installed on main line and washer machine per recommendation of plumber
- Plumber changed check valve at tank in crawl space - this did not cure the problem
- Do not believe there is air in the system - when running water we see no signs of air in the line
- Plumber would like to change check valve at well - not sure if that is the issue?
- Any fixture in the house can cause the bang - not specific to any fixture
- The bang has been happening since shortly after moving in
