Hello, I'm wondering if anyone in the know might have an opinion about what direction I need to take with this problem:
I have a Rockwood Mini Lite 1905 that is about 2.5 years young. It has a Suburban SW6DE hot water tank. The problem I am having is extremely low HOT water pressure - ONLY the HOT water is a problem, the cold seems normal. I have been reading these and other forums and trying to troubleshoot this problem but so far with no success. Here is what I know / have done:
1) I have checked to make sure the flow valves are both open in and out of the hot water tank, and that the bypass valve is closed.
2) I have checked to make sure that the outside shower head is off and both valves are closed.
3) I can verify that the tank IS heating water - very well - both on the propane side and independently on the electric side (have tested both).
4) The annode rod is new this spring with de-winterization done by a local dealer I have used several times.
5) I let the pressure out of the tank, removed the annode rod, and "flushed" the inside of the tank with a special hose wand for this purpose. Some sediment did come out, but nothing that would seem significant.
6) I removed what I thought was a check-valve on the "cold water in" connection, only to find that it was NOT a check valve, but just a connector. It had no obstructions.
7) I tried filling the tank (without heating the water) with the annode rod out - the tank seems to fill fine (no obstructions coming IN) and gushes right out of the annode rod opening.
8) The only thing I have not yet disconnected is the "hot output" connection but it seems like maybe there is "nothing to see there" (???)
I'm at a loss what to do next. Upon re-filling the tank and trying again, I am still experiencing very low pressure only on the HOT water side. The cold water flows just fine. I have also tried these steps both once with a full hookup (city water connection) and separately just the holding tank and water pump - doesn't seem to make a difference.
One thing I'm not real sure of is there is a valve inside connected to the pump - it is a T connection - seems not to impact water flow, but since I don't understand its function, I guess I don't know if it is set correctly. (???)
I have some pictures of my setup, with some notes, located in this One Drive folder in case that is helpful to anyone.

I feel like after having this camper 2.5 years, and previously other campers, I should be able to isolate this problem, but I can't seem to figure what step to try next other than the dreaded "trip to the service department"...
If anyone has any input on this it sure would be apprecaited.
Thanks,
Kevin
