2) Add comment with clear description of water heater, fuel type, and pump?
Is this a pump problem or water heater problem?
Is this a water well pump?
Are you getting good stream of cold water at tap?
Which water heater do you have?
Is the heater new?
Or older heater that stopped working.

Check your by-pass again. Cold water enters bottom fitting/line, and hot comes out the top fitting/line. Any valve in between should be closed, and any valve going in at bottom should be open, as well as open at top. There are a few different by-pass set-ups, so without knowing which one you have, this should guide you somewhat.
If you can describe what you see there, I can probably guide you through it.

You need to check by-pass valve(s) on back of tank for proper position. You need cold open going in to bottom tank fitting, and hot open at top. If any valves in between those 2 lines via "T"'s, turn them to off position.

If no hot water at any faucet, and your sure water in water heater is hot, check by-pass at back of tank for wrong positioning.

The first question is this
From the outside of your RV is the water heater square or is it longer than it is tall?

If it is square it is a Suburban
If it is longer than it is tall then it is an Atwood
Forest River mostly uses Suburban

How long do you let the unit burn/run before you try the hot water? From a cold start it will take - depending on the outdoor temp. & the gallon size of your water heater, 15 to 30 minutes for the water to get hot.

If you have waited this long then I would suspect the bypass valve is in the wrong position

you will need to have a 115 curent for electric, run a line off the panel box, turn off water to the house drain it down, disconnect the lp gas line and cap it off, remove the water heater, install the new heater run the cold side water to the cold side {blue on the heater} the hot side to the red, take the cover plate off on the water heater run the wires, hook up the groung wire then the red and white wires to the wires comming off the panel box,, fill the water heater with water have a open faucet on the hot side, and bleed the air out, DO NOT TURN ON ELECTRIC TILL THE AIR IS OUT OF TANK AND WATER IS FLOWING THRU COMPLETELY, after you get water commming out of the faucet turn it off and turn the electric on to the water heater ,, wait about 30 min, you will have warm after an hour it will be hot and you are done,, good luck write me if you have questions, [email protected]

You have a cracked dip tube. Part at hd is under 10 dollars. Remove and replace via cold water inlet side top of water heater. Degree of labor skill 1-10 = 8.
