The plaster has been expired likely for more than 10 years. Waiting longer to re plaster is greatly compromising the structure of the entire pool. Evident by the multiple rebar blemishes seen, pits and missing plaster, and overall poor worn patterns present.

Prolonging the current surface life will allow the rebar blemishes to expand and further compromise those areas / spreading the rust throughout the shell.

The surface is also shown to likely not be water tight due to chemistry results present (low cya and low cal hardness)

I am honestly surprised this surface is in such good shape for its very old age (2 years newer than me = 1986). Most pools would be on the end of their second finish by now.

The cost to correctly address the 3 different rebar blemish areas (+$2K each x 3 ... but there may be more seen upon closer inspection when drained. Note the process of CORRECTLY addressing the specific areas of concern (rebar) is to open these effected areas open 24" around, down to the rebar / dirt and re-enforcing + overlapping 18" of rebar around the areas of issue (in short).

+ the cost to replaster is approx 12-18K due to age, size of pool, and overall condition of plaster / shell seen.

Split at skimmer throat north west, this alone is an indicator that the skimmer itself will either now or soon, need to be opened up (jackhammered out), reinforced / restructured / replaced skimmer (also due to age and condition), and finally reset / re set (3-5K would be an estimated cost for this process, common on older pools) = At that time consider separating the main drain line from the main drain areas from the skimmer thus slowing flow / reducing flow potential, if this process is performed, opening the concrete decking in some fashion would be needed to allow this to occur, but this is very much a benefit on a pool this size.

Heavy calcium build up seen. Expect a cost of $800-1200 for Calcium removal

or

Likely a better value is to consider a Re tile as this is approx 1500-2500+

Concrete coping border on north side of pool is raised due to settling which is also likely causing the skimmers pressure and cracking. Recommend when re doing skimmer to leak a flexible mastic border around the skimmer to avoid future settling issues. In the mean time recommend attention to the raised concrete lip / trip hazard = lowered recommend repair / grinding 500-1000.

Low cya / cal hardness are signs of new water (less than 90 days approx) or water loss in this pool. Both are equally likely.

We have high ph and alk = indicators of organic matter proliferating in this pool.

Recommend attention asap as algae is beginning to develop, now ($375+ )

There appears to be two seperate main drains present and if T'd would be compliant due to distance from one another, but likely this is not the case due to age.

Note in the mean time (before the pool gets replastered) the covers should be updated for safety ($250 x 2), this would not make it VGBA compliant but it would make it safe to stand / kick to avoid injury from plastic that breaks under pressure.

At time of replaster the cost to update these main drain covers to channel style drains would be approx 1K each x 2.

The skimmer as noted in the tile section due to age and condition should be updated. In the mean time recommend updating the float, float o ring, weir door, weighted basket, and skimmer lid ($500 or less).

Normally a cleaner such as this can be maintained (similar to a bicycle), but when left out of the pool for prolonged periods of time, the hose and internal plastic parts suffer greatly. This unit while not very old is due to be serviced at least = new hose , tail , maybe tires , internal service ($250-350) vs a new unit complete is $650, and may be the best value, which can be determined at time of service.

Leaking during use, due to be serviced ($250+) which will likely include updating the seal or unit complete.

The one pool light (east) may be covered under warranty and I am not sure why such a nice light presumably less than 3 years old is expiring, but IT appears to have condensation present inside the light lens and if so is due to be replaced for safety. The cost to replace with a like Pentair Arch. Series (if Color?) Led is $1200 + install labor $400

The other west light is clearly due to be updated due to condensation present inside the light lens.

Recommend replacing both lights with like lights =- $1200 x 2 + install labor ($500+)

This filter is a great filter, one of my favorites, but at 60 GPM this filter is slightly undersized for the up to 100 GPM filter pump (https://www.pentair.com/content/dam/extranet/nam/pentair-pool/residential/pumps/superflo/user-manuals/superflo-pump-manual-english.pdf)

If running through the solar, this pump is likely in its ideal zone for this filter (40-60 GPM)

Still a better pump would have been the Superflo VS or THE most ideal **** Pentair I3 1.5**** (to allow you to dial in your flow rate specific to this filter)

Overall this filter should have a flow check valve added asap to avoid damage to this unit = https://a.co/d/03iGDvBL ($400 installed) = not required if using the Pentair i3 pump

To help prolong its life.

This filter again is a great option, but since it is undersized for this pool it will also need to be cleaned every 1-2 months if left uncovered for most of its life. Also due to the age of the filter (5 years) it may be near the expiration of the sand inside the filter due to the higher than required flow rates, therefore a sand change out is needed in the next 1 - 48 months ($750 or less).

Without major issue, just dirty, but I reconnected the conduit separation while I was there.

Sadly this is a very nice booster that may be expired, therefore a repalcement unit is approx $650 + hard plumbing ($500) + install ($400).

This cover pump appears to be in ideal working condition, but should be connected to power directly vs extension cords in settled water (safety issue).

Also there appears to likely be undersized wire connections being used for this high wattage motor = recommend a direct wiring connection to the motor for longevity likely installed by an electrician ($500-1K).

While I ran the solar for 30 minutes I did not find any visible leaks. When I shut it all off I could hear air escaping from this first picture seen. This may be a sign of issue or it may be an equalizer line functioning. Either way recommend service to this area to confirm ($500) and at the same time add a new temp sensor for the roof and one for the water temp ($500).

The actuator is functional

Working panel, but no GFCI except for the lights / plug which is great but due to age and condition of the pool lights able to be powered with water / condensation present inside the light lens (west most light) these should be updated at the same time as the other breakers to GFCI for safety ($400 breakers) + electrician fee ($500).

Both timers appear to be functioning, the west most is for the fitler pump and the east most is for the booster pump, ideally the booster timer should be programmed to come on only when the filter pump is running first ($100).

Not salt, but Chlorine Erosion tower, this towers hoses and fittings are due to be updated, low cost items + service ($300 or less).

Old, non servicable 2 way and check valves all expired causing higher pressure than needed, recommend a complete removal and replace with high quality valving ($1K-1500 depending on quality).

Note recommend covering from UV asap + painting and re labeling ($100)
