How to test if water pump is good on my 2002 Cheyenne?

Hello, all-

We have camped in our popup, but did not use the fresh water tank or the water heater. We are getting ready for another trip soon and thinking it will be cold, I want to use the water heater and fresh water tank (upcoming camping site do not have water hookup, only electric). I know the water heater works since the previous owner showed me hot water running when we bought it. But, he had the fresh water line hooked to his home outlet. I should have checked if the fresh water tank system was good, but I guess I was too excited . Later, I found out that the hose to the fresh water tank was busted, which I bought a new one and fixed. I also checked the water tank and there appears to be no leak/cracks. Couple of questions:

1. Currently, I do not have a battery plugged in (I am planning on getting one soon). Before I do, can I use home outlet (using a 30 amp adapter), to check if the water pump works (of course, after filling the fresh water tank)?

2. I also do not know if there is a switch or something to turn the water pump on. I am posting a picture where I can see two switches when I lower the sink. I think one is a main shut off switch (on the right top corner). And, the one on the left - is that the pump switch? Which means when I pull up the sink, the switch is turned on and if the fresh water tank is full and the pump is working, then turning on the cold water faucet should give me water?

3. I also have an outside shower - should it work the same? Meaning, if I turn on the cold water faucet of the outside shower, I should be getting water, if all system is working?

Please note, I do not have a battery hooked up yet - do I need to, to check the water system or can I use my home outlet to test this?

Thanks so much in advance for your help and comments.

Thanks so much @Sjm9911 will do and let you know how it goes....

 

@Dback2k4 , YES! I believe the tank has not been used in last 6 yrs at least if not more, so definitely, I need to 'sanitize' it - good reminder! BUT, the pump has to work first .

 

@Sjm9911 , @Dback2k4 , and others, I have one more question. If I got hot water through the faucet when PO showed me that the water heater was working, does this mean that the water pump is okay? (please note the PO had water line hooked up to his house outlet). The water heater does not have water pump, right, so the water pump that should work with fresh water tank water is good?

Thanks!

 

Ouch....okay, I get it - thanks...I will soon find out if the pump works or not...I have a feeling it may not as it has not been used for many (at least 6 yrs)...it is not that expensive and not difficult to install - thinking of the worst...

 

@Dback2k4 , I haven't had a chance to 'mess' with the water system, yet. I have plans to open up the pup in a day or two (have a camping trip planned next weekend), and check it and get back to you all. Thanks to all for the comments and suggestions.

 

Thanks @CampingFamily1 , when connected to shore power or the battery, I hear the hum noise from the water pump if I turn on the switch. I have had couple of trips sine I posted this question, but surprisingly, I have not had to use the fresh water system in our PUP! Somehow we managed to get by! Part of the reasons I didn't use it was that I needed to remove the anode rod from the water heater and clean it, plus sanitize the fresh water tank. I recently did these and will test out the pump and water heater in the next week or so. Thanks so much for replying to my question! All the best to you.

 

Hi, @CampingFamily1 , good suggestion. I will need to open the camper this week to get ready for an upcoming trip and will test it out. Will keep you posted and thanks again for your advice and helps!

 

Hi @CampingFamily1 ,

So, here it goes....I set up the PUP yesterday and today I put water and bleach to sanitize my fresh water tank. And, I thought to 'test' the pump. I turn on the pump, it makes 'hum' sound and I open the faucet, and nothing comes out. I wait for few minutes and nothing happens. I open the water inlet valve from the pump and water drips out, and I also open the screen and clean it. Put them back together, start the pump and nothing happens. Does this mean my pump is 'bad'? I am attaching pics and video with the sound so you can help, please.
I looked at amazon and these pumps are not super expensive. https://www.amazon.com/gp/product/B074MZYS37/ref=ox_sc_saved_title_1?smid=A2EFSDTWMPHWEA&psc=1
But I don't know if I can put one 'easily'. The wire connection is nothing like what I have seen before. I have installed ceiling fans, sink garbage disposals, dishwashers etc., so I can do stuff, but I don't know about this. See the wire connections - one of them has something like an in-line fuse as well!
(I can't upload the video, sorry).

 

Hi @mpking , @CampingFamily1 , great suggestions. I will first test the pump with tubes to see if it works or not, that I think should be my first attempt. I'll go from there.

Now, if the pump turns out to be okay (although not the best one ), I want to understand how the water heater comes into picture. Because, I do not know if the heater is full or not. I know the heater works, because last year when we got the camper, owner had the water hooked up with his a hose from his house and showed me that the heater works. I have since then changed the anode rod and cleaned the heater. I haven't turned it on, yet. Let me first test the pump with the tube and I'll get back. Again, many thanks for your help, always!
