The surface of the pool specifically on the walls has organic matter, build up present. It appears it is likely a black algae, dark green algae variant that should be able to be removed with service. It appears to be located on approximately 10% of the surface most specifically found on the walls.

Upon initially entering the backyard, and seeing the surface, I felt that it was wear present, but upon closer investigation, it does appear that the discoloration present is organic, and likely only on the very top of the surface. Therefore, it is possible that this material can be removed with direct treatment. If it is removable, it will likely require an Acid type treatment directly to it ideally with the pool half trained to accomplish ($500+).

There also appears to be a fine layers of sediment present that is covering approximately 50 to 65% of the pools surface, making it partially difficult to see the entire surface for inspection- the sediment is likely from previous chemical treatments to assist in removing the algae and this sediment is what remains. This will have to be likely vacuumed from the pool ($150+) to properly, dispose of all the organic spent material.

Overall, the surface appears to be likely between 20 to 25 years old, and typically plaster last up to 30 years. Overall, it appears the surface is in fair condition for its age but I do see stains present rust colored in the shallow end, as well as staining present throughout the surface in different locations ie returns.

The tile is in working condition, I did not locate any issues other than medium calcium formations present on only approx 20-50% of the pool. Still I would expect to see the cost to clean the tile be approx $800-900 in service if desired.

Water quality indicates that new water is present: Leaks found at the solar connections and potential leak found at the skimmer. Therefore new water is likely present as a result of this or all of the above and more.

Recommend treating the algae directly via a drain and clean ($500+) or with chemical only ($375+). I do not feel chemical only option is best.

The skimmer does appear to have chlorine damage Present to it - it also appears to likely have leak repair work performed to it. If the Skimmer is found to be leaking in the future, expect to pay $1500 or more for a new Skimmer installed.

Needs a new weir door, and Skimmer float and float O-ring ($150).

Also recommend leak testing the skimmer as well ($150).

Last recommend updating the main drain cover for safety ($100+).

The bottom cleaner unit itself, and some of the hose segments appear to be newer and less than three years old. The tail and some of the hose swivels will likely need to be updated ($105+).

The manual fill functions however, the fill valve itself does leak in two locations and maybe wisest to simply replace it with a manual hand valve ($250+).

The pool lights does turn on and function however, it does appear that the breaker to the pool light will need to be updated to GFCI for safety ASAP ($250+).

The light does appear to be older, and I would anticipate this light to ideally last another one year to five additional years before replacment will be required ($700+).

I also recommend cleaning behind the light lens as there is significant algae present here ($100+).

The filter could not be fully tested due to issues with the filter pump - But due to age and condition seen I would expect this filter to have less than 1- 3 years of potential life left before replacment will be required.

A new filter will be a Tr-100c / Tr-140c as a most ideal filter or as a budget filter but quality is the Ta-80 or Ta-100 or for budget the Sd-80 is the best value and quality for price.

A new Tr-140c installed is $2750
A new Sd-80 installed is $950

The bonding wire is not connected with an unshielded, copper stranded wire, Recommend and Updating for safety ($120).

The pump also does not turn on consistently has a loud motor buzz sound coming from it. Recommend updating the motor with either a variable speed motor ($585-1000) or a new variable speed pump ($1200-2750 installed).

Pentair models: Superflo Vs & i3
Would both be ideal options for new.

This pump is older but in working condition.

A new booster installed is $1250 for high quality BoostRite or low cost Superpro $950 installed.

GFI/GFCI/Light Breaker/Plug is not connected to any light, recommend service to repair and upgrade this issue for safety ($245)

The Valving and equipment pad needs to be updated ($750+) = 2 new check valves if needing solar or 1 if not. 1 new 3 way valve and plumbing.
