Seaflo submersible pumps can be used in areas such as yachts, RV & bottled water, as well as some edible equipment areas.

Seaflo 12 volt submersible and line pump 280GPH and 500GPH can pump 40℃ of diesel and 80℃ of salt water; 200GPH can only pump 80℃ of salt water, not diesel.

Because the float is slightly lower than the impeller, it can be drawn to a lower water level. This automatic bilge pump has lower water levels than other automatic bilge pumps.

It is better to install horizontally, a little angle is no problem, but not too big.

Can not be replaced, will affect the function of the pump.

The small size of bilge pump about 600 hours, larger size of bilge pump about 700 hours.

Don't worry. 
Fresh water pumps have to  be 100% bested before leaving SEAFLO factory.
Our quality control team undertake a hydrostatic test for each pump.
Thus, there is residual water in our new pump head.  

Not necessarily. Showers normally take less time since the additional water helps you.

 All diaphragm style pumps have a slight pulsation/vibration. This pulsation or vibration, if allowed to transfer through to the floor or plumbing lines, will cause amplification of this vibration throughout the coach. Mounting the pump on a solid base will resolve most noise issues.
  

Provided you have 12 volts and the pump motor is running, check for water/air leaks in plumbing, or a clogged strainer on pump inlet. Foreign debris may have entered the pump, requiring service of the valve assembly.

Answer: The pump cycles off because the shut-off pressure of 45 PSI has been reached. If it shuts off with your faucet or shower running full open, it is seeing excessive resistance (flow restriction) in the water supply plumbing.

1. Clean or remove the water savers in your faucets and shower heads.

2. Remove as many elbows and tees as possible at the outlet of the pump, and replace with approved flexible hose Look for restrictive valves.

3. Increase the shut-off pressure setting of the pump by turning the adjustment screw on the switch clockwise 1/2 turn. Note: We recommend this be done by a qualified service technician.

4. Install a SEAFLO accumulator tank to reduce cycling, keep water flow constant and even out temperature fluctuations.

Please check below
1. Correct Voltage (± 10%) and electrical connections
2. Fuse or breaker
3. Pressure switch operation
4. Turn off the pump
5. Take the two connectors from the pressure switch and connect them with a suitable gauge wire or alligator clips
6. Turn pump on
7. If the motor runs and the pump is working as usual, you need a new pressure switch
8. If the motor does not work, check your wire connections from your power source to the pump. Most likely you will need a new motor

9. You can utilize our store locator to locate new pumps

10. Rectifier or motor for open or ground circuit

Please check below
1. Loose screws at switch or pump head
2. Switch diaphragm ruptured or pinched
3. punctured diaphragm if fluid is present

1. Purge all the air in the system and check for leaks in your faucets or lines. If no leaks exist, you may have debris in the check valve/switch or valve assembly.
2. Clean debris or replace the check valve or valve assemblies.

Yes, you may choose the same installation mount and inlet & outlet pump. Details please check product page installation draw.
