Re: water hammer issues

When a older house was plumbed, air chambers were typically installed behind the walls. These are teed off of the feed lines to your fixtures and are meant to have air in them to cushion abrupt water shut off. The water "bounces" in the air chamber thus no sudden stop of water flow. Over time, the air in these chambers is absorbed into the water. If your house has these installed, shut off your main water supply valve and open your faucets, both hot and cold, allowing them to drain. What will happen is air will work its way back into these chamber. Close the faucets and open the supply valve. If you have these chambers, your problem should stop.

Re: water hammer issues

Sounds like the solenoid valve on the washing machine is causing the hammer...

65 pounds is normal water pressure in the DFW area, has been since I lived there in the 1980's - 90's...

If you have a PRV and an expansion tank, I don't know if installing arrestors will help - might need to go into the attic (if water lines are present) or into the wall between the kitchen and laundry and physically strap/secure the water lines.

Water hammer, if left to IT's own devices, will eventually cause a leak somewhere - no ifs, ands or buts...

Unsecured water lines are frequently the culprit here, due to poor training, installation methods and inspections.

I hope this helps...
