The pool surface is approximately 21 years old but it looks to be in distressed condition overall with much pitting present throughout the entire pool. This is a breeding ground for the black algae that is present throughout this pool it has spread on walls tiles and almost the bottom in prolific fashion. There are additionally rust colored stains in more than 10 locations throughout the pool initially I thought that it may be potentially rebar related which is very well may be but unfortunately in this instance it is likely due to be tested first to confirm by attempting to treat at least one rebar potential stain on the shallow end step at a cost of around $100 in service to treat one stain and if it is a rebar related issue expect a rough cost of $1000 to repair each rebar area correctly (open it up repair the rebar itself reinforce it reseal it with concrete and then later resurface it) and additionally it could be that some of them maybe 1 or 2 or three of them may be rebar all the rest may just simply be surface stains which may be a potential as well but again I am seeing rust stains even outside of the swimming pool on the decking and various locations so again I do not feel that these are all rebar related and that really only one or two potentially could be rebar related one on the bench shelf and one towards the southeast corner. Still when the time comes to resurface which it is very very soon in my opinion as we are also seeing check cracking spreading on top steps edges I would estimate a cost of around $10,000 to $14,000 to re-plaster the pool.
Estimated cost grouping: Stain treatment to confirm $100 plus rebar repair per area $1000 plus resurfacing $10000-14000.

The waterline tile all appears to be pretty well worn at the mortar point. This is indicative of what we are seeing with the algae buildup in the same location. Recommend attention to the mortar which may run $500 to $1000 to have them re-order this area but this would likely be best performed at the next re-plaster stage because the replastering is likely due very soon and it will create the best product if it was done at that stage. Additionally around the lions head water feature sconces it will likely need to be waterproofed around the border to prevent dribble from penetrating into the tile wall ($500). There are two issues with the coping one is on the southeast side of the pool. The concrete is disintegrating and separating from the coping edge. This is likely a simple fix less than $500 and on the west side of the pool there is a gap forming between the concrete and the tile in an unusual location approximately five tiles large and approximately a half an inch in a gap this might need to be filled with mastic for less than $500 but still it is curious as to why this is being created. I do see settling on the back southwest area of this concrete area which may be exacerbating this. There is minimal calcium buildup likely it has been removed in the past one to two years but there is some calcium buildup forming nothing too drastic but it could also just be simple calcium cleaning where which may have caused the algae buildup in the missing mortar locations because this has this is likely been where calcium cleaning has gone through and removed calcium but also removed mortar as a result.
Cost summary waterline mortar and sconces $500-1500 plus coping fixes less than $1000.

Water chemistry is in poor damaged condition. The chlorine levels are zero. The pH and alkalinity are high which is what I expected with the amount of algae present. The signer acid level is also high which warranted itself for a quarter drain at least and the calcium hardness levels are also slightly high. In general it may be wise to just drain acid wash and then refill and rebalance. The drain and acid wash would likely be around $700 and the refill and rebalance for the chemicals only would be close to $200 and that would likely be the best solution based on the quantity of black algae presence and the variety of locations.
Estimated cost grouping: Drain acid wash $750 plus refill and rebalance $200.

The skimmer has all parts present but I would still update the float the float ring the skimmer basket to a weighted basket and the skimmer lid ($500 or less). There are two main drain covers in the deep end and two in the shallow end. The two in the shallow end are likely equalizer lines or waterfall suction lines. If only one of these two is the waterfall suction line then this is a hazard and will need attention which could be modified at the equipment pad with relative ease likely less than $600 but if these are both for the waterfall suction port then recommend updating these covers as well. In fact I’d still recommend updating these covers due to age and condition as well as the two in the main drain of the pool so for a total of four approximately $100 each to install new covers for a total.
Cost summary skimmer update $500 or less plus main drain covers $400.

The Polaris 360 is relatively new. However it has a lot of metal degradation with rust on stainless steel bolts which indicates that the chlorine level of this pool is relatively high for a large period of its life, this is also evident with the yellowing inside the skimmer basket. Still the bottom cleaner needs a new tail tires and possibly some adjustments or parts inside the unit. I would estimate this along with possibly some new hose segments if needed for less than $105.
Estimated total: Bottom cleaner service less than $105.

Without issue.

The east light is not affixed correctly to the wall. It will need some minor adjustments probably less than $100 and the west light appears to be secured correctly. Both lights have a lot of organic matter buildup around the light niches recommend cleaning on both of them to assist with algae removal probably $200 and the east light also has more condensation present inside the light lens than the west light indicating that it may be nearing failure in the next 1 to 24 months versus the west light seems to have very little condensation present if at all again this is common with high chlorine level pools. The cost on a new light as this one is approximately $700 by Hayward color LED light plus install around $400

The filter is older and original. It is fairly sun worn but it likely has some additional life left maybe 5 to 10 different years left. Still the filter itself is leaking from its bottom. Hopefully it’s a simple fix with an O-ring and lubrication service on the bottom of the filter less than $100 in service or it could be a catastrophic issue where the filter has split and therefore the bottom half will likely need to be updated or replace that around $500 which I feel is the least likely but still possible option. Still the filter elements inside the filter are also going to need to be updated and replaced in the next time that we get all the algae out of the pool the cost of that filter element that will be between $300-$600 depending on quality of filter elements you get and then also at that same time recommend changing the filter pressure gauge maybe $50 for a liquid filled pressure gauge as well and also service to this filter will be around $150 in service cost plus everything mentioned previously.
Estimated cost grouping: Filter O-ring service less than $100 or split repair $500 plus elements $300-600 plus pressure gauge $50 plus service $150.

Recommend attaching a bonding wire ($200 or less).

Like new.

The board and timer is up next. It does appear to be a working Jandy Aqua Link system. It is working without issue. It is currently connected to a iAquaLink 3.0 phone control as well as a Jandy PDA handheld all appear to be working. I did not test the iAquaLink 3.0 via the app but all functions on the pool panel were operating. Additionally I was unable to get the PDA to connect which means that they likely removed its connectivity to allow you to connect via the app only. Also the safety updates I recommend are updating the breakers to GFCI Siemens at around $100 each times 2+ the pool light GFCI. I do have a GFCI plug which is fine but it would be wise the parts for the GFCI Siemens breakers are around $250 for the two and the light pool lights will likely run total of around $350 the electrician to install that will likely charge around $350 to $400 in labor.
Estimated cost grouping: GFCI breakers and parts $250-350 plus electrician labor $350-400.

The salt cell looks newer however it does not appear to be connected potentially as I’m not seeing any power going to the auxiliary controller for it even with the filter pump running indicating that there may be a additional issue. Worst case there may be some parts that need to be updated including a new power center or power supply of some kind that’s why I put the cost of $1400 even though it likely only needs between $100-$500 in repairs but it could be up to $1400. Recommend service ($205) to confirm.
Estimated cost grouping: Salt cell service $205 plus potential repairs $100-1400.

The valving on the waterfall pump has an energy bowl with an element that appears to be older and may be due for replacement recommend approximately $100 in replacement cost which will include a internal filter as well as a liquid filter pressure gauge. Next we have the energy bowl for the bottom cleaner. This should likely just be removed and re-plumbed around the filter for less than $600. Next we have a three-way valve for the suction on the pump. This is very hard to turn and showing signs of failure recommend updating this as well for less than $700. On the return for the salt cell this is working as far as hydraulically but it could be slightly improved and just simply adding a erosion chlorine tower dispenser for less than $500 installed would be a better choice here then either the floaters in the pool or the chlorine salt cell. I’d like to also repaint and re-label the equipment pad for less than $300 and then cover it from the sun using UV mesh for less than $50 and 95 to 99% UV mesh.
Estimated cost grouping: Waterfall energy bowl $100 plus bottom cleaner energy bowl $600 plus suction three-way valve $700 plus salt cell return dispenser $500 plus equipment pad repaint/relabel $300 plus UV mesh $50.
