Water Pressure

We just recently changed the hoses for filter and heater and this year our filter pressure is running at 20, is it possible the hoses are too long which would cause the pressure to be too high.

Is there a minimum length the hoses should be?


Hi Ellen. You did not describe how long the hoses are or what length you changed from. If you are talking about the filter system being moved back away from the pool by 20 to 30 feet, that could make a difference. If you are talking about going from 6 to 8 feet it would not make a difference.

The farther away from the pool the pump is set the less effective it will be. Or put another way, a larger pump is needed to draw water from long distances.

I have never heard this to have an effect on the pressure gauge, so I'm guessing it is something else. Pressure gauges are not the most reliable and it's possible it just needs replaced. This would be the case if the water pressure going back into the pool seems the same but the gauge is reading higher.

If the water pressure is greatly reduced you may have used the wrong type of filter media. Or it's possible you are having pump problems and it is not pumping the water like it should. An air leak could also reduce water flow.

It might be something a local pool repair shop could better help you our with.
