The pebble plaster surface is in good condition but has small, rust-colored stains, likely topical and not rebar-related. A $450 service to treat and remove these stains is recommended, which will also confirm if they are rebar-related, though this seems unlikely.

The waterline tile in the pool, likely original to its construction, is in good condition overall, with visible gaps only around the skimmer area; The skimmer will need to be re-waterproofed with new mortar soon, but no significant tile replacement is required now; monitoring the tile is sufficient, but it is likely that the waterfall will need new mortar waterproofing soon as well so the estimated cost at $1,000 to $2,000 to do both at the same time is projected to be necessary within 1 to 10 years, potentially longer if salt is not used, as salt accelerates deterioration.

Next is the spa’s spillover into the pool that has structural issues and delaminating tile, primarily at the corners, requiring new tile work estimated at $1-2k + or more, depending on the damage extent.
Total estimated cost for the skimmer mortar waterproofing, waterfall mortar waterproofing, and spa spillover tile repair is $2,000 to $4,000 or more, depending on the spillover repair scope.

Your tap water has high pH and extremely high alkalinity. The pool water exhibits high pH, very high alkalinity, elevated calcium hardness, zero free chlorine, 0.5 ppm total chlorine, and cyanuric acid levels between 20–30 ppm. Surprisingly, no algae is visible on the pool walls or elsewhere, likely due to copper elements in the water, as evidenced by blue staining on the deep end return above the step. High copper levels in the water are not ideal, as they can cause various side effects, including water chemistry imbalances, staining of pool surfaces, and potential skin irritation. If the pool has elevated copper levels, a partial drain or a full drain is recommended, costing $100–250 or more.

If the pool was recently drained, and there is no copper in the water, do not drain the pool.

To properly rebalance this pool, recommend adding CYA and chlorine asap and likely some small treatments to likely reduce the hiding algae (seen around the skimmer throat) ($100-200 or less).

Note that chemical levels currently are not obvious signs of water loss, this can be confirmed in 1-30 days by retesting the water as well.

The spa has two main drains, one being a specialty drain likely tied to an in-floor cleaning system with a specialty MpX cover costing around $150 to replace installed, and a smaller 8-inch cover costing about $100 to replace installed. The pool also has four main drains, one with a similar specialty MpX cover costing around $150 to replace installed, and another cover costing about $100 to replace installed x 3. Total cost for all replacements is $700

The skimmer for the pool and spa is fully intact with all parts present and nothing missing, so no replacements or repairs are needed at this time.

Shorten the hose and likely a new tail soon, otherwise this is a like new unit that just needs some minor adjustments.

The auto-fill float for the pool and spa is very old, likely original, and due for an update. The float itself is inexpensive, costing a few dollars, but the repair, which may involve additional labor or components due to the float running continuously, is estimated at $125 to $250. Updating the float could resolve the issue, potentially preventing water loss from a leak.

The pool has two incandescent lights. The west light shows significant condensation (50-75%), and the southeast light has minimal condensation (less than 10%), indicating failing or failed seals that could allow water intrusion and pose an injury risk. Updating both light cans is recommended to prevent this. Replacing the west light with an LED white Pentair light (100 feet) costs approximately $900, and the southeast light (under 50 feet) costs around $880. Installation for each light is about $350. Total estimated cost for replacing both lights, including installation, is $2,480

The spa has a 6-inch light with over 90% condensation inside, indicating a failed seal and the need for replacement to prevent water intrusion and potential injury. Replacing it with a white LED Pentair light (less than 50 feet) costs approximately $750, with installation around $350. Total estimated cost for replacing the spa light, including installation, is $1,100.

The filter has a failed pressure gauge, needing replacement (~$50), making it hard to assess the filter elements’ condition. Back pressure in the pump basket suggests slightly high pressure, indicating the filter needs cleaning. A service call to clean elements, move the tank, and service O-rings costs under $150. The four filter elements, likely due for replacement, cost up to $500, with a new tank O-ring at $100. The filter is sun-worn but still usable. Total estimated cost: up to $800.

The TriStar VSP 900 filter pump operates via automation but its motor display is blank, possibly due to a faulty display or improper wiring. Manual operation without panel programming is essential for field or service use. Replacing the display costs ~$500 if faulty; service to diagnose/rewire costs ~$125. Total estimated cost: up to $625.

Note for reference a new pump complete is approx $1200 for a Superflo Vs (comparable to this pump - if not better) or a Pentair i3 at $1900 + install.

The booster pump is operational, with past leaks that seem resolved and no current leaks observed. No immediate recommendations except to consider replacing hoses with hard plumbing to extend pump life, costing ~$450. Total estimated cost: $450.

For the 2010 waterfall pump with a suspected bad capacitor (replacement under $50, service under $500), if the capacitor fix doesn’t resolve the humming or if metal wear is severe (a sign of an expiring motor), a new motor may be needed, costing around $500+. Alternatively, a new variable speed motor installed could cost $1,500+ including installation. Check capacitor first, inspect seals and wear, and evaluate motor condition to decide on repair or replacement.

The heater functions well. Recommend painting the gas line ($50).

The Hayward Pro Logic board and timer for the pool and spa are in damaged working condition with a display that’s “on the fritz” and may soon expire if left exposed to the sun for prolonged periods of time. Using the remote is most ideal with this situation, but all programming must be done on this panel, making it essential to be working properly (as the filter pump is also minus a display).

Also, the older breakers need to be updated to GFCI for safety, with an estimated cost of $300. Two additional outlets have been updated to GFCI, but one is not resetting, and the other appears to be non-functional. One or both GFCI breakers may need replacement if faulty, at approximately $50 each. Additionally, installing a water bond is recommended for an extra layer of safety, especially given the 120V overhead lighting near the pool edge, with an estimated cost of $400 installed.
Total estimated cost for updating the breakers, replacing one or two faulty GFCI breakers, and installing a water bond is $750 to $800, depending on whether one or both GFCI breakers need.

Also note that the update to this panel is a Pentiar Easy Touch Lite or IntelliCenter

Or a Pentiar i3 pump with built in phone automation.

The salt system’s cell, over 10 years old, isn’t producing chlorine and likely needs replacement. A new salt cell costs ~$900, plus ~$150 for programming and installation. Alternatively, cleaner sanitation options like UV or ozone systems, ranging from $900 to $3,500 based on output, are viable substitutes.

The 2-inch PVC plumbing for the pool and spa is functional, but older valves and check valves need updating. Install a manual heater bypass to improve efficiency of the existing heater’s internal bypass and extend its lifespan. Replace check valves will all be recommended updates soon (1-10 years) = $1-2k. Needed now is to Paint and relabel the equipment pad ($200), then cover it with a $50 UV-protective mesh.
