When to use water pump - easy question from a first timer

We just got a 2011 26TBUD and are taking it out for the first time this weekend. This is our first TT, and this will be our first time using a water hookup. We've been trying to figure this out - when we run the sink, shower, etc., how does the TT know to pull water from the water connection vs the fresh water tank? All we could think of was that we should only turn on the water pump when we do NOT have a water hook-up. Is that correct?

Thanks in advance!
Kara

yes that is correct - water pump only when NOT hooked up to city connection

I am fairly new to owning my own TT but not new to camping

Congrats on the new Trailer

forgot to mention that you need to have water in the fresh water tank before you turn the pump on or you will burn the pump up - never run the pump dry.

also to answer your other question - when you have the city connection the water pressure from the hose pushes the water thru the camper when you open a faucet - you will notice slightly higher pressure with the pump over the city connection as well. Good luck this weekend and post back with some pictures of how the trip went

OK, here is another opinion.

The water system has check valves (one in the pump itselft and ine in the city water connection) that prevent water in the trailer's plumbing from exiting through the pump or the city water connection when pressurized.

When city water is hooked up the pump check valve blocks that water from turning the pump backwards and filling your fresh tank to overflowing.

When pressurizing from the fresh water tank and the onboard pump, the city water check valve keeps the water from flowing out that connection FROM the trailer.

You can power the pump with city water hooked up, but it should never run. The reason is that the "turn on pressure" of the pump is about 35 PSI and your city water pressure is typically 40-50 PSI. The water pump is designed to start at about 35 and shut off at about 40 PSI. So if you have city water and turn on the pump, nothing should happen as long as your city water can provide at least 36 PSI when being used.

When running off the fresh water tank and the 12 volt pump; the pump "may" start and stop when you turn on the switch. It is sucking water UP from the fresh water tank (runs dry briefly then fills the pump head and pressurizes the system) then shuts off. If it continues to run you might have an air leak between the pump and the fresh water tank (or check your antifreeze fill selector).

I don't know if you have one already. But it would be a good idea to use a pressure regulator when hooked up to city water. Sometimes the water pressure can be inconsistent, and the pressure could be too much. Which would damage your water lines.

Thanks everyone. We do have the pressure regulator thing - the PDI guy recommended it so we purchased one the day we picked up our TT.

Congrats.

You will soon find out there are 3 levels of quality for these pressure reg devices.

1. Plastic
2. Brass
3. Brass and adjustable with a gauge

I myself have gone with door #1 - which I left on the spigot somewhere in West Virginia...

I then purchased a brass model -I still have that one. Works great to date.

Many highly recommend the adjustable one with gauge - but at $50+ it's more than I want to spend right now.

A good buy to protect your plumbing.

Another item would be some sort of a strainer. When I had my old trailer, the hot water heater stopped working. After replacing the heating element, still didn't work. Later on found one of the water hoses about 9-12 inches long filled with sand, apparently from the city water pump (new wells). Wayne
