Main reason for pump seal (mechanical seals) in a pool pump any pump for that matter is to contain liquid (water in this case) in the pump and hold prime and pressure. Other reasons, lower friction,reliability it can last for years.

How is an above ground pool pump different from an in ground pool pump?

In simplest terms, an above ground pool pump is a flooded suction pump, which means the water level must be higher than the pump for it to operate, and an inground pump has the ability to draw water up from a level lower than the pump. The engineering and structure of these two different types of pumps is what makes them work the way they do. This means that, in a typical installation, you could use an inground-specific pump on an above ground pool, but not an above ground pump on an inground pool with the water level below the pump.


Can an in ground pool slide be used for an above ground pool?

Generally...no. In simplest terms, an above ground pool pump is a flooded suction pump, which means the water level must be higher than the pump for it to operate, and an inground pump has the ability to draw water up from a level lower than the pump.

If you have an inground swimming pool system that has an air leak and the pressure is 12 psi with no water leaks how can you find out where the air is coming from?

Do you have air bubbles coming back to the pool thru the return lines? If so, you have a suction leak. Could be between the skimmer, maindrain, at the pool pump. Most likely place to start is the pump. Check the lid o-ring for proper seat and fit. Check the pump seal. Check any fitting that goes into the pump pot - in and out plumbing plus small plugs at the base of the pump. K


Can you connect a garden hose to a inground swimming pool pump?

You can probably find the plumbing to step down to the right size but the pool pump will have more water flow then a garden hose can safely handle. Your going to ruin either the pump or yourself.

How do you tell by looking at above ground pool pumps verses inground pool pumps if they will work for my inground pool?

They will most likely work, they just have to have the same specifications.


Inground pool Your pump is sucking air and leaking when off what could cause?

I have the same problem. From what I've been able to find it is probably the mechanical seal between the shaft of the electric motor and the pump body or housing. Directions are on the net to replace these. Should be fixed as it can ruin the bearings on the motor. RJ & Eddies Dad
