Increase Flow Rate

by Amy H
(Socorro,NM,US)



My current water meter is reading 50. I have tried greasing, checking dirty debris in basket and skimmer, and checking for possible air leaks in the pipes.


Immediately after adding grease I noticed a slight increase in water meter, but still can't reach up to the standard of 70.

I need to increase my GPM, any suggestions? I have a hayward pump with a sand filter.




Thanks for the question Amy

I would first ask where the meter is located, either in the suction or return side? Some people have them in different places.

If you have a suction side problem you can go to my YouTube video to learn how to troubleshoot that:

Let's say that there's no issue with either the suction or return side and the water is flowing. The only thing left is the GPM flow meter. Sometimes sand or a very small particle can clog the nipple that goes into the piping. Here's a nice way to clear it. You need 2 people for this.

Turn the system off. Take pliers and remove the red cap on top of the meter. Tightly hold a rag over the hole but give it a pocket on top. Don't hold the rag right up against the hole.

Have someone turn the system on. The water will shoot out of the top of the meter along with the small metal float. This clears the nipple in the line. You don't need to run the system for very long. It's turn on for 1 - 2 seconds, then system off.

Carefully release the GPM meter but hold on to the rag because you'll have the metal float. You don't want to lose that. Put the float back into the chamber and screw the red cap back on. Turn the system on.

I had to do this at the Y pool and it worked every time.

I hope this has answered your question to your satisfaction.

Where At What Is The Impeller & Pressure Steadily Risen As Starting Pressure After Back Washing?

by Melanie B.
(Las Vegas, Nevada)

I thought I was getting pretty good at keeping a nice clean well "balanced" pool..because I haven't had any big issues that your site didn't help me remedy..(thank you!)

However, I have noticed lately that the pressure in my Sand Pro 4510, is reading at about 10, as a starting pressure after backwashing and rinsing.

Originally the pressure would start at 5. I have an Intex above ground pool 18' x 48", and using the Sand Pro 4510 sand filter. I live in Las Vegas, NV. and having an above ground pool, is a challenge in itself, because we have more windy days than not, and I find myself doing a lot of vacuuming.

While I was reading some of the questions and answers on your posts, someone mentioned that the impeller might have debris in it causing the pressure to rise..hence my original question, (if I read it correctly).

I did have a small leak from the ring that keeps the top portion of the filter housing on the unit. I took it off, reseated the gasket, put some water based silicone lubricant on it and the leak stopped, but now the pressure reads high. Did I screw something up? Should I have done something else? How do I check the "impeller" for debris?

Sorry if I've rambled a bit, but I know you can help me..thanks. P.S. What is the air bleeder valve? (Guess I'm not as savvy as I thought lol)




Thanks for the question Melanie

First I'll address the rising pressure. It's normal for filters to rise in pressure as the filter gets dirty. You backwash it when the pressure gets 8 - 10psi over the "just backwashed pressure".

High pressure is when the water is being forced through a smaller and smaller area. It takes more force to push the water through, hence high pressure. This can happen with a dirty filter, clogged impeller, or debris in the suction line.

The impeller sits inside the pump housing. You have the pump pot, then the housing, then the pump motor. Turn the filter off and at the breaker. Remove the pot lid. Remove/unscrew the line going into the pump pot and on top of the pump housing.

You should have 4 - 6 bolts or long screw that secure the housing to the motor. Remove them, then remove the housing from the pump motor. You now should have access to the impeller. This is the piece that spins and pulls the water through the system. Clean it out and reinstall. Be sure any gaskets are clean and free of dirt. Lube them with Magic Lube.

That's the worst case scenario. If you don't want to go through all of that another easy fix is to turn the system off and remove the pot lid and strainer. Stick a short screwdriver into the hole and feel if the impeller spins freely. You may be able to remove some debris or blockage.

An air bleeder is a small valve normally found on top of a sand filter. This is used to remove any air that's trapped in the filter.

For your sand filter I will quote the owner's manual for releasing air in the system:

"While pump is running, loosen, but do not remove, one of the screw-on transparent covers on the filter tank to allow any trapped air to escape. Tighten the cover once all of the air has escaped."

I hope this has answered your question to your satisfaction.
