The surface has blemishes present throughout, and mottling making a difficult to identify additional issues, but I do not see any apparent obvious issues at this time. I would estimate the surface is between 15 to 25 years old. There is where between the tiles indicating it is closer to 25 years. Plaster surface, typically last up to 30 years or possibly more if we maintained, typically when water loss is observed replastering as then required.

There is heavy, calcium buildup, that can be removed for about $650.

Do you water waterline tile all appears to be in fair condition overall, slightly difficult to see due to the calcium buildup present.

There is a small gap, forming between the tile and the concrete, especially on the east side of the pool that can be filled with mastic if desired ($1k+).

The pH and alkalinity are both very high, the CYA level is also slightly low (30-40), the chlorine is absolutely through the roof high, recommend attention to rebalance these as well as treat for a light algae presence mostly seen on the shaded wall ($250+)

The skimmer is missing. It’s float and I would recommend also adding a weir door, and a new float o ring ($250).

There are two main drain covers both are due to be updated for safety ($100x2).

The Pool apparently does have an auto fill mechanism. It is hard to see fully and this was likely designed for an aquarium, but it does appear to be functioning, I’m not exactly sure how we can get serviced …

Still, the supply line that runs to the auto fill is leaking and will need to be fixed ($125-250+).

It appears to be a low voltage system, therefor a junction box may not be required, recommend confirming if this is in fact low voltage ($10).

This filter has a pressure gauge that is nearly impossible to read ($50), but it does appear that it is between 20 to 25 psi during operation, indicating the elements insider likely due for replacement ($500+) which will be determined at service ($150) and at service it may require a tank o ring ($150) replacement due to the leaking seen. But in my opinion, I do not feel I would put any money into this filter versus replacing it with a Pentair Ta-100d @ approx $1k.

This pump is in ideal working condition without issue at this time, the only complaint I have is the conduit that is ran to. It is very tight and will likely snap with any accidental movement. Therefore, I would recommend a new conduit ($200+).

Recommend updating to GFCI on the variable speed breaker and the pool light outlet if desired for extra safety ($300 parts + electrician install ($350). You can also add a water bond if desired ($300).

The evolving installed is less than ideal. The solar valve is leaking and the section side has a temp sensor that should be moved as well as a water temp sensor that has been spliced to repair these items I would estimate around $500 or less, but it might be wise to cut out all the old bad ABS the old check valve the old valves and update all new at approx $1500+.
