The fencing is non ideal and should be updated for safety.

The surface could not be fully seen due to low water quality, but the surface that can be seen (steps) is showing signs of wear, with pitting seen at the top step. This is typical for plaster on the last 25% of its life cycle. Now the steps may be the only issue and can be patched ($500+) but if the pitting is present throughout it is a sign to replaster soon.

The cost to do a “fast re plaster” would likely run $4-6K+ vs doing a full replaster ($6-10K). Vs painting ($1500+).

No missing or loose tiles.

The coping has some signs of slightly lifted concrete that can be grinded ($500+) and re filled with mastic for approx ($1500).

A low cost solution to bring this pool back to blue and clear is to add 4 gallons of liquid chlorine, then testing the chlorine level again every 1 day to see when the free chlorine level goes down to 1, then if at a 1 or below, add another 2 gallons and re peat this process until blue and clear. Cost will likely be $150 in liquid chlorine, or consider draining and starting fresh as this water appears to be older (higher calcium hardness levels).

OR for approx $550 pay someone to do drain and refill.

The main drain is likely due to be updated to VGBA status. A temporary fix would be a simple SDX RETRO cover from Amazon for approx $50. And or at time of re plaster update the drain to VGBA status ideally with a channel drain ($500+).

The skimmer has parts that are due to be updated ; float , float o ring , weighted basket , updated weir soon ($200+)

It does not appear to have a cleaner present. A suction side cleaner is approx $500 or possible a return side cleaner wound run $650.

Likely this valve body is due to be updated.

Could not see the light but I do see a junction box, I wound assume the light can is due to be updated ($600+ light + install $400).

I wouldn’t spend so much time trying to rehab this existing filter vs just installing a new AquaStar 35001 filter ($600+ install $400). Or the most ideal filter a Ta100d $800 + sand etc ($300) + install ($700).

Or just servicing ($200) and adding a new element / internals / pressure gauge / etc ($500+)

High power, low pipe size. A recipe for over pressuring system and causing additional issues. A better A+ option is likely a Superflo Vs ($1100) + install $650. Current pump likely just needs some minor service ($100+) which may include o rings , basket , lid , return fittings

The panel is working. Due to have some updates = GFCI parts approx $200. The base / conduit is compromised and due to be re done ($300+).

Also if you remove this pump and install the variable I recommended, you can remove all of this and just install a single sub panel ($300 + install $200) as the best option for future proofing.

The equipment pad shows signs of water loss / due for updates.

If the leak is located under the pad, expect a cost of approx $3k to break the pad down, and find issue, repair, and maybe re pour a new low cost pad / plastic base.

If the leak is on the pad expect a cost of approx $2k to re do all the plumbing so it’s updated for the next 50 years+
