The surface appears to be older than 7-15 years+. Either dust or wear present on the surface around the in floor returns. If dust, showing signs the filter is in distressed condition. Also the shell appears to be settled slightly lower in south west vs north east being higher described more in tile section.

Calcium present at waterline tile - can be removed if desired ($500+), some mastic loss issue that may need filling soon ($500+), some cracking present in mortar that may need attention soon ($500+). Water is uneven from east side to west side pictured comparing water levels.

Water loss is present (seen on the filter pump currently) , but it does not appear that the pool is all new water. Recommend rechecking the water chemistry and one to 30 days to confirm water loss status.

Recommend updating the main drain covers x2 and 1 wall equalizer line ($500) and at re plaster updating to VGBA (300+).

The skimmer needs a new basket , weir door, ($200) and service to throat soon ($500).

Also note that due to the likely slight movement of the pool body the skimmer is getting twisted / compressed and causing it to buckle slightly. The skimmer appears to have been replaced in the past 15 years and it appears that it may require another replacement in the future, in the next 1 - 20 years+ if the buckling continues. A new skimmer installed is approx $3500.

The system is not working correctly either because of a lack of maintenance to the gearing system or the pop-up heads are older and due for updating - Approximate cost to update this In Floor Cleaning system is described in valving section.

Working. Recommend minor canister clean out ($125-250).

There are three lights. All lights appear to have condensation present inside the light lens, west is least, middle south is present and east is worst. East light appears to be colored while the other two only shine white, still appear to be colored. Rec updating all light canisters for safety ( $500 incandescent or 1050 led color x 3 + install $750 ).

This is an older filter, any upkeep on this would likely cost more than replacement. A repair / upkeep would include a new element set ($500) , new internal maintenance including o rings ($200+), new pressure gauge ($50). Vs a new filter complete $500+ which would be a far better value.

This pump appears to be split at the pump housing, and will likely need a new wet end installed ($1250) to regain this as a working pump. Note a new pump entirely is approx the same price +. Note this pumps cooling fan is impacted and needs to be free of restrictions.

I feel a Pentair Superflo VS new at $1100 would be a better value.

The updates required will likely include new GFCI variable speed breaker, pool, light breaker, and water bond ($750+).

1400 reading. It is most likely both salt cells are due for updates ; $900 x 2 + maintenance (salt levels etc $450+).

3 valves , 1 in floor cleaning Valving, 1 in floor suction pot, all due for service ($1750+). Note bypassing the infloor and using it as returns only would save approx $1000
From that cost estimate.

Recommend covering and painting from uv.
