Swimming Pool Sand Going Back Into The Pool

by Cheryl
(New Jersey)

I just changed the sand in the sand filter. The laterals were fine. I had them checked at our local pool store. I put in 5 bags of sand. Now I have pooling of sand and the bottom of the return valves.


I think it is entering the pool during backwashing, but I am not sure. What could be causing this problem?

Thanks




Thank you for your question Cheryl

There could be a few reasons why you still have sand going back into the pool. You said the laterals are fine so we can rule that out.

Swimming Pool Sand Filters

1. You need to rinse the lines after you backwash. When the pool filtration system is backwashed there's debris that get caught inside the lines.

2. With new sand you're gong to have some dirt and residue which will eventually get filtered out. This is normal and shouldn't be a concern.

3. If the sand media is going back into the swimming pool each and every time you backwash and the above is covered, it might be your multi-port valve. Have that checked and replaced if needed.

4.Be sure your swimming pool sand is at the right level. Check your owner's manual on what the right level is for the sand.

Psi Gauge For Pool Filter

by Cristina
(Gainesville, VA)

I just open my pool and when I finish putting the water I turn the filter on, my psi gauge is on 10 and I can't get it down to 0. I did a backwash and still on 10.

What can I do? Do I need to replace the psi gauge and if I do, how do I do it? Is that part something that will be cover by the warranty of the filter?





Thanks for the question Cristina

It may be under warranty but that's something you need to check with the manufacturer.

Now for the gauge itself. A simple test for a working gauge is to turn the pump motor on. The needle should jump to the right level. If you turn it off and the needle drops, it means the gauge is working. If you turn the system off and the needle sticks at the same level, the gauge is not working and needs to be replaced.

It's as easy as screwing in a light bulb. Simply turn the system off, bleed the air out of the filter, unscrew the old PSI gauge and replace with a new one. Be sure to wrap the threads with a little plumber's tape.

I hope this has answered your question to your satisfaction.

How Do I Start My Sand Filter?

by Randall Capps
(Steger, Il.)

We have a sand filter for our above ground pool. How do I turn it on. There's no on/off switch nor a turn on button.

I've done everything according to the manual but it doesn't tell me how to get this thing going.




Thanks for the question Randall

Many above ground pool pumps have a kind of top cover. Underneath and/or on the back of the cover you may find the ON/OFF switch.

The other kind is sometimes found on the pool pumps. There's an ON/OFF switch under the back cover of the motor.

Check out these places to find the switch. The pump may have a toggle switch near the equipment that allows the pump to turn on and off.

If you can, follow the electrical conduit where the pump plugs into and hopefully it will lead you to this switch.

Sand Returning To Pool

by Tom
(Maryville, Tn.)

I know that you have actually answered the question of sand ending up in the pool through the returns but I have to ask again because: I was very careful with the laterals while changing the sand. They "seemed" to be fine. I did slightly crack the multi-port housing while tightening it. There is a ever so slight water leak through it. Is it possible that this could case sand to get into the pool? It doesn't seem plausible to me but I am clutching at straws at this point.




Thanks for the question Tom

The first question I would ask is if the laterals are good. You've said yes so the next question would be was the filter tank filled up 1/2 - 2/3 with water before sand was added? Water displaces the energy of the sand going directly onto the laterals. Not doing this can cause a lateral/standpipe to crack.

Let's say they're intact. If you just replaced the sand you'll get dirt going back through the returns. Sand is very dirty. This finer dirt bypasses the laterals. The only thing you can do is keep vacuuming it up until the sand settles in the filter. Eventually it will. I had to do this with my customer's sand filters and the filter at the Y. Two huge Triton II sand filters. I knew I was going to vacuum once per day for about a week until all the sand settled.

Once it does settle you'll need to check the freeboard. That's the measurement from the top of the sand to the top of the filter. Your owner's manual and/or the manufacturer will have that info. This helps the filter run at peak performance.

If you feel your situation is more complex than this, I do phone consultations. It makes things go much faster and many people have found it extremely beneficial, saving them time and money in the long run. All your questions will be answered. I have nothing to sell you so you know I'm not bias.
