No water pressure with pump

I have a 2012 xlr 35x12 and when I try to use the water pump, it doesn't build any pressure and I can hear air bubbling in the tank. Whats wrong? Thanks

It is possible the two wires going to the pump are reversed. Try switching the wires.

It attempts to pump water out of the faucet so it doesn't seem that its pumping backwards.

But your post said it is bubbling in the tank. Sure soundls like it is backwards. Easy to switch wires.

This can't be it because of the check valve that keeps city water from entering the fresh water tank would prevent it. If the wires were reversed (for some reason) the pump would run basically dry.

For the OP, do you know where the pump is located?

No/low water pressure from the pump using water from the fresh water tank and no city water connected could be:

1) Pump not running (check fuse at pump)
2) Check valve at city water connection open (or broken) water running down outside of camper
3) No or low water in fresh water tank. (pump sucking air)
4) Low pressure set on pump adjustment screw
5) Screen bowl on pump clogged with silt or mud from well water (use a prefilter on hose bib

That is what I needed to know for my pump no longer coming on. I checked all fuses and breakers at the main panel, but then after your notes, found a fuse at the pump (blown). Thank You

Check your strainer, sometimes debris from the tank (shavings from the build) will clogg the screen.

TROUBLESHOOTING
Vibration induced by driving can loosen plumbing, strainers and pump hardware to loosen. Check for system components that are loose. Many
symptoms can be resolved by simply tightening the hardware. Check the following items along with other particulars of your system.
PUMP WILL NOT START/ BLOWS CIRCUIT:
¸ Electrical connections, fuse or breaker, main switch, and ground connection.
¸ Is the motor hot? Thermal breaker may have triggered; it will reset when cool.
¸ Is voltage present at the switch? Bypass the pressure switch. Does the
pump operate?
¸ Charging System for correct voltage (±10%) and good ground.
¸ For an open or grounded circuit, or motor; or improperly sized wire.
¸ For seized or locked diaphragm assembly (water frozen?).
WILL NOT PRIME/SPUTTERS: (No discharge/Motor runs)
¸ Is the strainer clogged with debris?
¸ Is there water in the tank, or has air collected in the hot water heater?
¸ Is the inlet tubing/plumbing sucking in air at plumbing connections (vacuum leak)?
¸ Is inlet/outlet plumbing severely restricted or kinked? Restrictive valves?
¸ Proper voltage with the pump operating (±10%).
¸ For debris in pump inlet/outlet valves or swollen/dry valves.
¸ Pump housing for cracks or loose drive assembly screws.
RAPID CYCLING:
¸For restrictive plumbing and flow restrictions in faucets/shower heads.
¸Water filter/purifier should be on separate feed
PUMP WILL NOT SHUT-OFF / RUNS WHEN FAUCET IS CLOSED:
¸Output side (pressure) plumbing for leaks, and inspect for leaky valves or toilet.
¸For air trapped in outlet side (water heater) or pump head.
¸For correct voltage to pump (±10%).
¸For loose drive assembly or pump head screws.
¸Are the valves held open by debris or is the rubber swollen?
¸Pressure switch operation.
NOISY OR ROUGH OPERATION:
¸For plumbing which may have vibrated loose.
¸For a restricted inlet (clogged strainer, kinked hose, restrictive valves).
¸Is the pump plumbed with rigid pipe causing noise to transmit?
¸Does the mounting surface amplify noise (flexible)? Does it bang like a drum?
¸For mounting feet that are loose or are compressed too tight.
¸For air in the system. Check all fixtures for air and bleed system.
¸The motor with pump head removed. Is noise from motor or pump head?
LEAKS FROM PUMP HEAD OR SWITCH:
¸ For loose screws at switch or pump head.
¸ Switch diaphragm ruptured or pinched.
¸ For punctured diaphragm if water is present in the drive assembly.
