I’m going to talk to him tomorrow. Obviously, there’s a solution to this, short of him having to get rid of his aquarium. But I don’t appreciate the fact that he tried to lie. It means he doesn’t care about doing the right thing.

Marc, have you investigated the neighbors and whether they have aquariums? I didn’t realize it until I started doing some research but aquariums are the source of quite a bit of noise pollution.

Remind me, Marc. You said the hum started a few weeks after you moved in, right? And you didn’t hear it at your mother’s house in the beginning?

Have you been in touch with the water district or gas company? I will be calling both tomorrow to see if they can explain this hum.

We were planning to move when our lease is up in four months but it’s now looking like it will be a miserable four months. This is insane. I’ve since spoken to some neighbors and all of them said they do not hear a hum.

I’ve gotten some good suggestions recently. Potential sources could be the gas regulator at the gas meter. It can hum when demand is high. Also, could be the neighbor and his pool pump and the noise is filtering through our sewer lines.

I’ve been advised to call County Public Works and ask about potential projects that could cause the hum. Also, the water department, get them to do a pressure flow check on the house.

In situations like this, the simplest explanation is usually the correct one. We had a new water heater installed around the time the hum began. We thought the hum predated the water heater by a few days but really, we can’t be sure. We had that bad transformer in the yard that could have caused the noise we heard before the new water heater.

So, it is possible that the pressure is fouled up on the water heater. It’s a more power appliance than we had before. When the pilot light fires up and the water is being heated, it makes a loud humming noise. The plumber did some adjustments to the flue on installation and I’m now wondering if all of that is related.
