Yes, mine is noisy too. And as you can see it's mounted right under MrsBob86ZZ4's head when she sleeps. I'm told the new pumps are much quieter. When mine quits I'll surely buy the quietest one I can find. We never use city water pressure. I don't trust it. We always fill up the tanks when we leave home because I like our house water. And I don't want to take a chance of the pipes cracking from city water pressure and flooding us out. We always use the pump and turn it off when not using it.
