When running water pump, water is fairly hot and them moderately hot changing 3 second
When running pump with hot water, water is moderately hot and then get cooler to warm and then hot again, changing maybe every 3 to 10 seconds. Any idea where to start looking. Pump seems to have enough pressure shutting off when it gets up to pressure and then kicking back on as more pressure is needed, maybe 30 second cycle. The hot water tank heats up. Just have no idea where to proceed. I do not know if this is normal when running on water pump. Do not understand why water just does not run hot all the time. Why the fluctuating in temperature. Fresh water tank is full. Any help appreciated. John

Sounds like you may have the hot water tank bypass valve open.
Here is a basic picture.
Cold water in open
Hot out open
Bypass between closed.
Hope this helps
Notice the angle of the valve handle in relationship to line.

Is this the back side of the Surburban hot water heater. I know where the front side is with anode. Might have to start removing cabinet fronts. Heater is in the back of the Trailer.

It may be located behind a "false" wall. Mine was and it was removed and tossed before I got it out of the dealer's lot.

BTW SP 189 owners, the access door is behind the hot water tank and inside under the TV wardrobe on the bottom. Just remove the 4 screws that covers the panel. Screw are located in the corners and remove panel. You can gain access to the water pump and valves and the back of the hot water tank. Really easy when you know where to go.
