Howdy!



I am still working on my gmc. It's coming along, and I have made some nice
improvements. Now I am working and learning about the plumbing systems. I
have a list of stupid questions, mostly due to never owning an RV before,
let alone a GMC. J



1. When does the water pump need to be on, when should it be off?

2. I have a drain hose in the rear wheel well on the drivers side.
Water is coming out. where would it be coming from to come out that drain?
(I am using the water tank, not the city water inlet)

3. When I have the water pump on, and I open kitchen sink to allow
water to flow, it comes out the drain hose from question 2.

4. I don't seem to have hot water. the switch is on, fuses look good.
is there another on/off switch?

5. Does the coach engine or generator have to be running to have hot
water?



Notes: When I bought the couch I think all the drains were on, and I have
been finding them as I go. The owners manual doesn't exactly match because
the inside of the coach has been redone. J



Thanks for all the pointers!

Brian, I suspect a PO has put a Drain in your lines to the sink in kitchen. Turned on, so it is coming out. Get up in there and look at your lines. Mine are like that but up under sink is my shutoffs and drain. Last year mine leaked out that wheel well. It froze and pushed a connection apart. I got lucky. Put it back together and tightened. Worked, no leaks. I have the hot water drain in the passenger wheel well. The water heater will need a/c to operate.

Brian, I forgot: we leave our water pump on all the time when living in the gmc. When we are not using it we turn it off. I never hook to city water, just fill our on board tank.

Hi Brian
On your '75 Glenbrook,
1. The pump needs to be on when you want water from the tank.
2. Water out that drain indicates an open drain valve or a broken water line
behind the kitchen sink. It is very smart not to use city water until you
get all the leaks and valves sorted out.
3. Open drain valve or broken water line.
4. There is a water heater switch in your electrical cabinet. Be sure there
is water in your WH tank before turning it on. You can meter current at the
heater beneath the lavatory. The heater element is probably burned out.
Replacements are available at the hardware store. Engine heat will also
create hot water but might take 10 or 15 minutes to be realized. And,
you'll have to ensure that the hoses from the engine are still intact.
5. The water heater runs off 110vac or engine heat. So, it must either be
plugged into shore power or the generator running, or the engine be running.

Not dumb questions at all. We all got to learn somehow.

Some water heaters run off propane.
