Cold Water - Low Pressure

[Stargazer49]

A while back I noticed that the cold water supply to specific fixtures had lower pressure than normal (applicable to both pump and site water). Hot water at all fixtures is normal. In my rig, the cold water travels towards the rear, serving the kitchen sink, the outside shower, the inside shower, the toilet, and finally the bathroom sink. The low pressure appears only at the toilet and the bathroom sink. Any ideas? Also, the bathroom sink appears to be the last fixture for the water system. However, there is a T-fitting under the sink. Where would this extension go to? There are no additional water using fixtures at the back of the trailer. Thanks for reading, and your help! Bill

On my 1999 Brave the shore water is connected to a tee under the sink to supply the coach, from the opposite end as the pump. Check the plumbing diagram at Plumbing Diagrams

Hi Stargazer49,
Welcome to iRV2. It would be helpful if you include details about your RV. Brand, model, year, etc. Those with the same unit could provide a focused response.

I've had no trouble with this TT until this low pressure showed up.
