Thanks! That is likely a sta-rite crystal flo (first version, not II). That is an old filter. Unless one of the others pipe in, I know of no way to deep clean the filter, or replace sand without removing/cutting the plumbing.
I don't want to blindly spend your money, but you are likely better off by rebuilding your pad, get rid of the puck chlorinator, replace the pump and filter and add the swcg. I'd get rid of the booster pump which is not being used (it was for a pressure side cleaner). I would get rid of the black flexible connection, which was the booster output, but now bridged from the filter and pipe the filter output to both return. I would put Jandy never lube valve on the two inputs to the pump (main and skimmer). It will save you a bunch of $ and headaches in the future. A large cartridge filter is really low maintenance and would provide excellent service. Something like the Pentair Clear Plus CCP420.

Yea, I think so. The issue is not the MPV. The issue is finding the filter instructions, which requires brand/model. I found it from the MPV picture it is the crystal flow. It seems there is no way to deep clean, or replace sand without removing the MPV, requiring cutting the PVC.Maybe this

Cut the pipe and replumb as needed.
Lose the tab feeder.
Add unions.

Looks like the plumbing has been cut many times.
Seems like they should have put in unions instead of a gazillion couplings.
Maybe the old owner was Howard Schultz and he refused to have anything to do with unions?

Ok, let's ignore the equipment for a moment, you have semi-functioning equipment and the priority is the water exchange. Here is what I've found to work, myself and helping others.
1) you must do this in one fell swoop, not in stages You don't want water to mix as you are doing this, it will take longer.
2) re-read the no-drain exchange twice, print it out.

2.5) For the PWTDS and the FWTDS calculations, you can take the pool water to the pool store (yes, I know, we told you not to us pool store testing...TDS and metal testing only). If you don't want to do that, I'd assume that your PWTDS is high (use 1500) and your FWTDS is low (500ppm). My GUESS is that you want to fill to the bottom of the deep end and drain from the shallow, but either get pool store results or use my suggestion and YOUR water temperatures and do the DeltaT calc to determine where to add and drain.
3) Get a 5 gallon pail. Time how long it takes to fill it from your garden hose. My guess about a minute, most residential is 5-6GPM.
4) Drop your sump pump in the pool and time the same for 5 gallons. It likely will take less time. If it takes less time, raise the hose over a structure or a tall ladder, this increases the work the pump has to do and will slow down the flow. Try to find a configuration where your input and output are about the same flow.
5) GO! Turn off the pool pump. Start the fill and the drain at the same time. Re-check my math, but you have to exchange 18K gallons. 18KG / 5g/min = 3600 minutes / 60 min/hr = 60 hours of water exchange. Should get you to 50 CYA...as the drain article explains, you might do an extra 10% or 6 hours to account for mixing...you can always add CYA back.
6) Watch the pool every couple of hours...if it is dropping, turn the sump off for a bit. If it is rising, turn the input off for a bit. I got mine to the point it would change 1/4" per hour. I think it took me 53 hours to do my exchange.
Ask any questions, we got you.

You're awesome PoolStored! Thanks for all of the help!
I actually have a pretty good well nearby that can get me about 50 gpm. I'm hoping I can get the exchange done considerably quicker since I only rented the pump through tomorrow.
Regarding equipment, this is all a bit much to take in so quickly especially considering the nearest pool company is 20+ miles away and seem to have 2+ weeks backlog assuming they'd have everything in stock. I think I'll try to cut/repair the PVC to deep clean the filter to get me by this year. Then aim to upgrade to SWCG, VS pump, and more logical plumbing in the off-season.
On another note, neither skimmer has a door… I tried to eyeball the replacement at Leslie’s but of course it didn’t fit. You don’t happen to have deep expertise in weir doors do you?

Yeah, if you rented a trash pump and can get a 50gpm input, that would be great. HOWEVER, well water can contain IRON, which will stain your pool and cause other issues.
I noted about avoiding pool store testing. Before you go whole hog, get a well water sample and take it to the pool store and have it tested. Pool store testing is inconsistent and not recommended, EXCEPT for metals. No other reasonable way to get it tested at home. I would hate for you to exchange this pool, only to find out you are fighting high iron.
This IS one item, even with the 20+ mile drive, Iron is another B*tch to fight. If you have high Iron in your well water, we might look for another solution.

Yes, I can help with the doors, or someone else here will know
. You need weir doors, or you will not get skimming. Take the lid off your skimmer and look on the underside for any numbers and names, report back or take pics. We can either get original or aftermarket solution for you. These are important.

I'd like to note your high trust in me and TFP. I too was a skeptic. I couldn't find any place that would explain the WHY behind pool chemistry. This is the only place I found it. I trust the volunteer team here. We are all volunteers and have a high degree of honesty. I choose to spend my social media time here for these two reasons (honesty and transparency). I wouldn't make any recommendation to you or other members, that I wouldn't make to my daughter. We got you. You have a cool pool, and the opportunity to make it a low maintenance joy. We want to educate you so you know exactly what you are doing and why...and you can make the best decision for you.

When all is said & done water exchange wise an
Overnight Chlorine Loss Test will tell the tale if thats dirt or not. That’s what’s great about testing your own stuff. You get confirmation whether things are on the up & up or not. Your filter is definitely older but we’ve seen worse
At least it’s huge!
