Need advice to silence a noisy sewer cover

I think a bag of sand for $3 is a pretty cheap experiment. May as well try that first and see what happens.

You might try to epoxy a shim on the low side so it won't move. If not epoxy, there are some highly resilient adhesives that might work.

I think sand would be worth a try but don't see it working long term. I believe the lid sits on a metal ring so something must be bent. The best thing would be welding it but I can see a cop rolling up about the time you get started. You'd probably get even less sleep down town.

Maybe spray some foam around it. It might get under the lid enough to cushion it for a while.

See, I told ya. Make it disappear and they’ll fix it fast. Maybe put it on Craigslist

I think it works, it is silent now.

However, I did lift it slightly out of the hole with a crowbar last night to see how heavy it was before adding the sand. When I pushed it back in it seemed to have sat in differently at a slight angle and was a bit more quiet. But I was able to make it clank slightly by jumping on it.

I did rotate it before but never lifted it out. I doubt lifting it out had anything to do with it as all it would take was a car to seat it down properly and start clanking again if I didn't add the sand.

I then added the sand, and this morning I'm not able to make it clank at all when jumping on it. It was quiet all night also, was finally able to sleep late into the morning. Cars roll over it without making any noise.

I will see how long it will last, I'm going to add sand as needed which is no big deal because i have a 60 lbs bag of it.

Maybe all the tilers on here could ship you some dried up tile dust from the bottom of the tile saw water pans. That mud has got to be useful for something.

I think herringbone would look better than basket weave.
