I finished installing the sound dampening accessories on our new dishwasher tonight. I had waited on the off chance of leaks from the new installation. No leaks meant silencers were to be installed. This washer is quiet now. The air gap which prevents backflow contamination is now louder when it’s draining than the washer is when it’s running.
I am going to say this: if you have a washer without a backflow prevention mechanism such as an air gap: get one. I can think of no other cheap installation that could be better for your home repair money. I could have possibly saved my old dishwasher from replacement had I known about the air gap. Installation took all of 20 minutes because I’m slow and wanted to triple check the connections.
So far I’m thrilled.
Also, I fixed a broken closet door tonight. Tip: don’t cut corners with “repairs”. The previous owner of this house did and I’m having to make up for it in dishwashers and wood and time :). Not that I mind. After hours in front of a computer screen physical labor is refreshing.
