I have a 2007 Dutchman 31k. When on water pump i hve no pressure to cold side of sink and shower and also toilet. Hot side of sink and shower is good. When on city water all is good. Kitchen sink is fine on pump. Please help me figure this out. Thanks.
I finally found my problem. Under the bathroom sink are 2 dump valves. One on hot line and one on cold. The cold line dump valve was malfunctioning causing my cold pressure to drop off when on pump. They are small valves with metal rings on top. I hope this will help someone in the future.
