Dometic 310 toilet noise

[rapidrobert]

Installed a Dometic 310 toilet in my old unit. Happy with it but it makes a loud noise when the valve is shut off when flushing. Is this common with this unit? Any fixes for it?

My 310 in my old 3402RL thumped sometimes too when I am filling up the bowl with water ,it does it mostly when there is high water pressure in the resort ,I'm sure it is the pex lines making the thumping noise but I had gotten use to it and no big deal to Us, small price to pay for a far superior toilet,now I have to buy another 310 or 320 for my new Monty because the POS new Thetford is already screwing up and not holding water

I also have the Dometic 310 toilet & also mada the loud noise when stepping on the valve. I called Dometic to complain & they sent two (2) screws that fit into the back of the valve to secure the valve.
Noise has stopped.
