What Size Fitting on Dometic RV Toilet for Install of Bidet
Updated 10/22/2025 | Published 04/09/2025
Question:
What size is the water connection to a dometic 320 toilet? I am installing a bidet seat and the t valve is 7/8 x 7/8 x 1/2. I think Brondell bidet manufacturer offers different size t connections, but I do not know what size the inlet on the dometic 330 is? Can you help? Thank you. Charlie

Hey Charles, the Dometic 320 toilet uses a 1/2 inch NPT fitting so that would be the size fitting you'd need to use for the bidet install.

Hey Charlie, how did things go with the 1/2-inch NPT fitting on your Dometic 320 toilet? Did that size work out for your bidet seat connection? Your update could make it easier for others adding a bidet to the same setup.
