Need Simple diagram for Fresh Water System

I am rebuilding a small travel trailer and want to have manual pump and pressure water. I have a small tank now but don't know if i need to use 2 separate lines or "y" valve?

Can someone draw a simple diagram of what i need to do? Should I get a tank with an extra fitting and run 2 separate lines?

Since you describe the pump as a manual pump, it is likely not located near the fresh water tank. So assuming the pump is built into the faucet head, the pump depends on an unbroken column of water from the tank because it is drawing the water out. If you use a Y in the draw tube any small leakage in the other pump could cause the pump in use to cavitate and not draw water.

In short I would use two different hoses. Also, use the size tubing recommended for the pump (probably same size as the existing pump). If the tubing is too large you will also have problems maintaining the head.

Also consider, this might be the right time to convert the system to a pump system. The pump would be located at or near the tank. But it would require a source of 12volt DC and standard faucet heads at the sinks. If the trailer does not have built-in battery then this is a non-starter.

WaterPump

Thank you for the input, I ran 2 separate lines (one for the manual pump and the other for the 12 v Shurflo). Now I can have my pressure water, or I can use the manual pump (sans power).

I wanted the ability to have both like I had in my Yacht.

As you are building the trailer...with the tank as the source of water, a manual and 12vdc pumps as a means of moving it...what are the items you are trying to supply water to. Meaning sinks, shower etc.

If you are only supplying water to a sink in the 'kitchen' area that should be a simple drawing to provide. ShurFlo has a drawing/inst sheet that is basic and provides the necessary items needed.

This is a drawing I did on my unit and the 'older Excels'....
