Yesterday my Shurflo 65psi water inlet was installed. Old one was a 50psi Shurflo. It's in the garbage! I am getting 100% improvement in water flow within coach.
I showered this morning and enjoyed a good spray without having to run water pump. My kitchen sink performs a lot better. Well worth the $30 price tag. I've noticed that Amazon has increased the price, however, by 10% over the $30 I paid last week.
I will add that I have an adjustable water pressure limiter with gauge on the city water source and set at 61-62 psi. The park's water is high pressure and registers the full 61-62 psi on the gauge, but would be a lot more if not for the pressure limiter device I have.
