How to troubleshoot your pool pump motor:

The swimming pool pump consists of two parts the actual electrical motor and the wet end that contains the seal and the impeller. On the popular Hayward super pump these two parts separated by removing four 9/16 bolts on the pump. So the first thing you want to do to determine what is wrong with the motor is to see if you have power to it. Make sure to check your circuit breaker for the pool as well as any sub panel breakers that maybe outside as well. If the breaker is on on both panels you will now want to make sure that the time is on as well. Most in-ground pools will have a separate time that maybe off, and if you have an above ground or semi above ground you may have a timer as well. If you know you do not have a timer at all then just skip this part. You will also want to make sure that the pump is plugged in, I know this may sound silly but often, landscapers and other ground workers sometimes disconnect or trip over cords, this does not happen to often but it always can happen. If you have check all the power sources and you still have no power chances are your motor is no good or will need serious repair, your best bet it to replace the motor or bring it to a pump repair shop to see if they can rebuild or repair it, but in most cases its cheaper to buy a new motor. It will also make sense to buy a new motor if yours is several years old. If your pump is however in a newer shape it might be worth it to have it repaired.

How to troubleshoot your pool pump wet end:

The "wet end" of a pool pump is the part that contains the impeller and the seal. The reason its called a wet end of the pump is for the exact reason you maybe thinking. It's because water goes through this part of the pump and it gets wet, its as simply as that. The parts on the wet end of the pool pump are called, the impeller, seal, pump cover, pump cover gasket, drain plugs and also the volute which is also know as the pump housing. If your motor is good, meaning it turns on and no water is pumping through it , you probably have a problem with wet part of the pump and this can includes problems with the parts we just listed above,

How to make your pool pump run air free:

The first step to making sure you pump gets a full prime every time it runs is to make sure that all the places that can leak air are sealed tight. The places that you seal up to make sure that no air gets in the pump are the drain plugs, suction union or suction valve, volute gasket even and the pump lid gasket. These are the most common places that air will get into the filter system. So what you will want to do is make sure that the unions are tight and that the gaskets are not dry rotted, or cracked and also make sure that the drain plugs have a sealant tape on them if they are tapered. Please note that there are two different types of drain plugs. The first kind is tapered and will require sealant tape. The second type of pump drain plug has no taper but uses a rubber washer to make the seal, Often this washer rots away and then the drain plug does not have a complete seal. So make sure to check the pump drain plugs really well.

How to replace your pool pump:

Replacing a pool pump can be done with a few tools as pool pumps usually are only connected by two fittings and the electrical cord. You will need a large sized pair of water pump pliers and also a flat head screwdriver. Here is how to remove and replace the swimming pool pump:

Step One:

The first thing you will want to do when removing your pool pump is to make sure that the power is off and then you will want to also unplug the pump .

Step Two:

Now that you are completely sure that the power is off and you have disconnect the swimming pool pump power cord you will now want to disconnect the ground wire. The ground wire is attached by the ground clamp that will be attached to the top pf the motor. Take your flat head screwdriver and loosen the screw and remove the ground wire and place it to the side. The ground wire will be a copper wire coming from the ground. This is required on above ground and also in ground pools.

Step Three:

In this step, you will be removing your swimming pool pump completely from the filter and the base. To do so, you will have loosed the discharge union and the suction union of the pump. The suction union is the union on the front of the pump and the discharge union can be found on the top or side of the pump. If you have an above ground pool you will just have to loosen the hose clamps on the plastic hoses and then remove the hose hoses from the pool unless your above ground pool is hard piped then you will have to loosen the unions, as we described above. To loosen the unions turn the union nut with your water pump pliers counter clockwise until hand loose and then spin the union nuts by hand.

Step Four:

Before you remove the pump , make sure that the power is off , ground wire is removed and the unions disconnected. Once that is all done you can lift up your pump and remove it. To re-install the swimming pool pump just reverse these directions and don't forget to prime your pump before starting.
