I have a Megaflow system that makes horrendous vibration

Customer Question

Hello Pearl. I have a Megaflow system that makes horrendous vibration when the washing machine or dishwasher fills. I have replaces all 3 pressure relief valves, no difference. Plus checked pipes are not loose. Very frustrating - any ideas please. ( Have maintenance contract with BGas but they cannot help. )
JA: Sometimes plumbing issues that that you think will be really complicated end up being easy to fix. The Plumber I'm going to connect you with knows all the tricks and shortcuts. Last thing - JustAnswer charges a fee (generally around $18) to post your type of question (you only pay if satisfied). While you're filling out that form, I'll tell the Plumber about your situation and then connect you two.

Hi just washing machine and dishwasher?

There are only two PRVs on an unvented cylinder. Can you tell me was the other one a pressure balancing valve? these are often the culprit.

Also if you run another cold tap when this starts does it stop the noise
