Billy W. I like you like having it quiet at night so I installed an accumulator inline but the accumulator I purchased was not the RV type I got mine at a local lumber super store. I was wondering if you had to install a check valve inline? The reason I ask is after installling the oversized accumulator, my pump does not shut down and I have checked every inch of the camper for a leak and find none. Checked the pressure in accumulator on the air side and it reads 40psi. Other than pump runing constantly I like the 15 seconds of full flow water. Any ideas or help would be greatly appreciiated.
