I put a new tsu99a.x in my Gwyneth toilet. It still makes A lot of noise. (80psi)
What’s a good fill valve for a Gwyneth?

thanks!

That's the fill valve I like for those. Does the noise come for the shutoff at the wall? Sometimes there is a loose washer that flutters there.
I like to open the valve up all the way, and then back it in a bit.

No, it’s a new 1/4 turn valve. Wide open. The noise comes and goes.
Will the Kirby 528mp platinum work ok?

A brainstorm idea (no experience, just thinking about what would be causing the noise):

I wonder if adding a flow restrictor to the toilet supply line would moderate the noise that the fill valve is showing under excess pressure? If you have a 3/8" compression x 7/8" ballcock supply line for the toilet, and you have enough vertical clearance, you could put something like this between the stop and the supply line:

https://www.conservationwarehouse.com/supplylineadapter15gpm.html

They come in various ratings, I figured 1.5 gpm would still let a modern toilet refill sufficiently quickly. That site also carries a 1.8 gpm version.

Cheers, Wayne

I can’t change the City pressure. My house doesn’t have a pressure regulator.
Right, but if the city is giving you 90 psi, say, then the correct solution is to install a whole house pressure regulator, rather than modifying the toilet.

Can a pressure regulator be installed outside, below ground?

SOmetimes...depends on whether you can put it in a place where it's not likely to freeze. If you add a PRV, you also should add an expansion tank or you'll likely start to cause the T&P valve on the WH to open when it's heating water.

Plumbing fixtures are designed for pressure NGT 80-psi. It is not uncommon for the pressure to spike overnight as water towers get refilled and usage goes down, so you really want a gauge with a second, tattle-tale hand to record the peak pressure and leave it in place for a full 24-hour period to catch any peak.

Do you notice the sound more at night versus the middle of the day or morning, where the usage is highest in the system, and the pressure may end up lower?
