First time to use trailer without water hookups - have questions

Going to to use the trailer next weekend without city water hookups for the first time. Will fill up my water tank before leaving home (only going 10 miles). I've only ever used the pump for winterizing... how do I use it for the sink and shower? Do I just flip the switch on and that's it? The pump will just come on as needed? I will have power... any issue using the hot water heater?

We won't be using much water inside, but the toilet will be used all weekend. I may not be able to flush the tanks until the following weekend (going to a campground Easter weekend). Is it ok for the tanks to have liquid in them for a week? I will use the necessary chemicals in the black tank, but I've always flushed them right after using for the weekend, so I don't know how this works.

Thanks for the help!

When you first turn on the pump open up a faucet to allow air to purge out of the system. Turn off faucet when only water comes out.The pump will also fill the hot water tank which will take 6 to 10 gallons depending on your tank size. After this the system will pressurize and the pump will stop running on its own, and not run again until you use water. So since it is an on demand pump, you just use a faucet or shower whenever you need it. I see no reason why leaving stuff in the waste tanks a week would be a problem. On edit if you winterized the trailer then you will have to turn the bypass valves by the water heater to fill the hot water tank with water. Otherwise it will just bypass it as with winterizing. -Lee

That is what I was hoping to hear!!

Now, when I'm filling the freshwater tank, how do I know when it's full (other than the gauge)? When I go to drain it, do I just pull the low point drains?

Fill her up till she runs out the overflow under the trailer. Also purge your lines and fill your H20 tank before you leave home, then top off your water tank, that way you carry maximun water with you.

Not sure your temps there but if warm, I suggest some odor control chemicals in your waste tanks to hold down the odor for the week.

If you need to conserve water may think about taking "navy showers" for the weekend.

No reason to drain the fresh water tank (unless you have weight problem) until you winterize this fall. We always leave some (1/3) water in our tank. Stop along the road and use potty etc and have flush water.

No, do not pull the low point drains. There should be a separate valve somewhere on the water line that runs from the fresh water tank to the water pump. That's the one that drains the tank.

Actually the words "low point drain" are on the trailer above the fresh water tank valve on the Jayflights now. You open this valve to drain the tank, I do it whenever I`m done using the trailer for a few weeks. It is directly below the fresh water fill on my trailer. The other low point drains are in the back, below the outside shower. No need to open them up.

I have two places on the frontside of the trailer that are labeled 'low point drain.' I have noticed that nothing ever comes out of them, so I assume these are for the tank. I have two other valves under my fridge that I pull to drain all of the plumbing (this is also how I drain the hot water heater... a lot easier than removing the plug on the actual heater. Just open the valves and open the pressure release on the water heater).

Good to know that there is an overflow valve of some kind underneath. I wasn't aware of that.

Also, good idea on leaving a little bit of water in the tank for use while on the road or while not hooked up. Hadn't thought of that!

The tank drain is closest to the fill area. Don't forget to turn the pump off when traveling and at night. They loose pressure and power up when you are sleeping.

Thanks for the tips. Any idea what the other outside 'low point drain' is for?

Yes, that's true and on my TT there are three outlets protruding from the bottom of the TT where the front low point drain is marked. They are:
  1. The water line drain
  2. The fresh water tank overflow
  3. The fresh water tank drain

However, unless you're winterizing, you only want to drain the tank; whether it be partially (for those who prefer to keep some water in the tank for traveling purposes) or fully (My preference). If you happen to open the water line drain, you're going to have to bleed the air out if the water lines and replace any water in the HWT that may have escaped when you opened the valve.

DISCLAIMER:
Unfortunately, the locations of valves, tanks, and the water pump vary among the makes and models of trailers. Therefore some of what is said here is not the Gospel and should be used only as a guideline. For example: My fresh water tank is in the front of my TT, but yours could be in the rear. All my valves are located inside my TT, but your trailer could have one or more valves that are only accessible from the outside. Keep this in mind unless you're talking "model specific".
