Hello all! I have been looking through the forums on this site for days, and I’m at my wits end.
I am the sole maintenance person for our family’s inexpensive (now I realize that in pool ownership there is no such thing) store bought above ground pool. It’s a summer waves 16’ x 48’.
I made the decision going into this summer to upgrade the pump to a sand filter.
I watched some videos and decided on the Intex SX 2800 Krystal clear sand filter.
Several issues right away:
1. The filter did not come with plunger valves or hose adapters. I was able to get the hose adapters from a semi-local pool store, but then didn’t remember about the plungers until later…. Like after I had gotten everything set up.
2. When I opened the pool this year it looked like a pond. By far the worst water situation I’ve encountered in the 4 years since first getting this type of pool. I HAVE successfully improved this situation and I believe it would be resolved if the other filter situations going on weren’t happening.
3. Due to the water quality I have had to backwash the filter quite a bit. I only just yesterday discovered that I can vacuum to waste, so going forward this will hopefully be side stepped.
This brings me to my current situation. After one backwashing last night when I turned the pump back to filter it is now blowing white foamy bubbles from the water output back into the pool. Clearly the pump is sucking air. And I believe I know from where. I have the intake hose attached with an adapter at the bottom/phalange from the factory pump casing that is attached to my pool wall. When I initially set the new sand filter up and it was on the water level maintained even with the pool in the old skimmer/pump casing. However, since yesterday the water is being sucked from the old casing as fast as it can fill, like flushing a toilet. The water level is good. There’s no water leaking from anywhere.
Could the sand possibly be too low from all the backwashing? I’m at a loss and don’t know where to go.
To add onto the pile, I am now returning to the issue of not having installed the plunger valves at the beginning. Is it possible to check the sand without the plungers/ or water just running everywhere the entire time? I am so new to this and the pump manual is no help.
Thank you to anyone who has stuck around this long!
 
By "plunger" valves I assume you mean check valve or one-way valve. You can add those but another option is to add a regular shutoff valve for when you do maintenance.

Your filter has little to do with water clarity and nothing to do with water sanitation. It collects and stores particulate matter in the water column.

The 1st step to a trouble-free pool is a proper test kit and doing your own water testing.

I totally agree and am not so much worried re: clarity right now. I am testing my water and trying to keep at just below shock level chlorine as my water had so much algae. My alk and Ph are good.
My pump shooting out foam is the biggest thing I’m trying to address right now. And by plunger valve, yes this is a valve that allows the water flow to be adjusted.

At this point you need to run a SLAM. Before that, you need a complete set of test results. Most notably, chlorine and CYA levels as that determines what chlorine level you will need to maintain throughout the SLAM process.

But really the key is understanding how to manage your pool. Without that you'll just end up where you are again.

Can you post pictures of the foaming? Also can you see inside of your pump pot (is the lid clear)? If you have a leak, that of course needs to be corrected.

SLAM Process
 
in addition to photos of the foaming, can you post photos of the pump/filter set up including lines in and out of pool?
 
While the filter isnt the end all be all for clarity.. Having it figured out aides the issues by getting rid of those particulates that cause some of the haze, but aren't affected by the chems.

By all means add a FEW shut offs, a little redundancy goes a long way down the road.

Don't get to over whelmed, take little bites each year. Focus on the MAIN problems now.

Once you get it dialed in. You want to kiss yourself the times you check your levels, not because it looks hazy (because its crystal clear) but more so you can just verify.

There is an end....

And yes closing is a HUGE factor to the next years opening.
