Hi everyone, I'm a complete newbie to motorhomes, and my plumbing skill could use a little help too. I have a camper van with a Carver Cascade 2 (at least that what the little brown switch next to it says). It's also has a submersible water pump that goes in the water tank, I don't know if it's made by whale, but looks similar.
Anyway, to the problem details. The pump stays on continuously when I turn on the pump. If I adjust the pressure by tuning the little plastic valve which I believe is the pump pressure valve, I can get it to pulse about once a second, but I know that's not right either, as it continues to pulse as long as the pump switch is on. As far as I can tell there's no wiring coming from the sink or the shower taps, that means there's no electric switches in the tap right?
Possibly related, and another issue I have: I can't get any water from the hot tap. When I turn on the cold tap, the pumps currently continuous noise changes tone and cold water comes out fine from the cold tap. When I turn on the hot tap, the pump doesn't change tone, and no water comes out, nothing happens.
I checked the heater, The little brown control switch has a green light on it. I don't know if it's on or off, as no matter where the switch is the green light stays on, and I tried to get hot water in both postions. I tried to press the reset button on the front of the heater itself, but it appears to be already depressed. Well, it's not flat against the suface, but when I tried to press it, it didn't move. Pulling it out simply pulls out slack on the button, but doesn't actually pull anything out. I don't know whether this is how the button is supposed to be, and I'm being weak and not pressing it hard enough, or whether it's already been pressed.
I've tried various combinations of turning the hot tap on and off, leaving it on for a a minute or two to see if it just needed time. I have no idea how to stop my pump from being on continuously, or how to get hot (or any water) from the hot tap! Any ideas? Please bear in mind not only am I a newbie at all this, but the van is new too so I don't know it very well and it didn't come with any manuals in regards to the water and heating system.
Here's the water heater:
I've put a bunch of other potentially helpful images in same place as this one, you can see them all at http://imgur.com/a/znD8G, I didn't want to fill this post with images. They're all labelled, but if you would prefer me to post them inline, let me know.
EDIT: I forgot to say, I have working gas, the carver gas heater (on the opposite side of the van to the water tank) works fine.
Thanks a lot for any help and advice you can give!
