Newbie Questions

I apologize in advance for any redundancies.

I recently purchased a 1962 28' Ambassador and have some questions regarding the fresh water system. I have filled the tank with no issues, did not see any leaks etc. Mine fills on the streetside of the coach, there is a flip open door with a gate valve to connect a garden hose.

Here are my questions:

1. I left the garden hose connected in the RV park for pressure, I assume this is the correct procedure?

2. I see a lot of talk about water pumps, I am assuming that is for when you are not connected to a city water source.

3. Where would the water pump be on my coach? The tank is under the rear double bed on the streetside. I would guess that the pump should be in that vacinity.

4. There is a light switch over the sink that does not seem to be connected to anything, could this be for a 12V pump? I have not removed the bed to see if there is a pump there as I am not sure where it should be.

Any words of wisdom on my questions are always appreciated. I have learned a ton from this site, everyone has been great!

Hi there, and welcome! This is a great resource, and hopefully you can find answers to all of your questions here.

I can get a couple of them:

1) Yes, leaving your hose hooked up is fine. You may want to get a pressure regulator to make sure you don't have surges inside the coach. they can be found at all RV stores. you also may want to shut the water off in case of leaks if you will be away from the coach for an extended period of time (you just never know with hoses).

2) Yes, the pump is for when you don't have pressure. It always helps to carry a good spare if you use your pump!

3) The water pump may be close to the tank - possibly under the bed. That's where it is in our motor home, but I can't say for your application for sure. Other folks will know that one.

4) Dunno about this one, sorry! We have a rocker switch in the bathroom, apparently for the water pump, but it seems to do nothing. I will have to look it up in our manual one of these days...

Good luck, and enjoy your great Airstream! We'd love to see pics if you have them!

I don't know the answer to #4 either, but in my Caravel there is a switch in the kitchen by the sink and this is for the pump. In my trailer the pump is located under the side gaucho.
And congrats on the new trailer! I'm a newbie too - lots to learn

Louis, on our '61 Overlander there is a light switch next to the stove top that is for the water pump. On ours, the water pump(12v) is under the kitchen sink and it pressurizes the tank(our tank is original). Our tank is also under the street side bed & the fill connector is street side. It sounds like the configuration simular.

Be sure to use a hose rated for potable water - a garden hose isn't. They sell lovely white ones at walmart and other places rated for drinking water - no nasty chemicals to leach into water.

In my sis-in-law's 67 Ambassador, her pump switch is in the kitchen close to the sink. Im not sure where her pump is at the moment, but will find out tomorrow!
