The surface has signs of wear / blemishes present.

One seen in the mid deep end south east side. Steps have spider / check cracking.

Overall surface appears to be 15-25 years old. I would expect this surface to be on the last 20% of its life cycle.

The blemishes seen in the deep end is likely of issue and will require attention soon - it appears to be surface / delaminating plaster vs structure (but only can be determine once opening it up.

If just de laminating plaster - most likely , a re plaster will resolve issue. Re plaster of whole pool is approx 6-8k 15 year or 8-12k 30 year. If a structure issue, expect 1-4k if additional issues are present.

The cost to patch these areas ; steps and de laminating would likely run (2-3k+) but it would be wiser to re surface the whole pool as the best value.

The coping in the south section of the pool will need some grinding / mastic work to not be a toe hazard (500-2k+).

The water line tile has some hollow spots around the skimmer and may require attention ($500-1000+).

There is calcium present recommend cleaning ($550+).

The poor water quality may be related to it being older. Recommend a drain and re fill ($100+) for the easiest , freshest water vs treatments ($200+).

Cover is older and likely due for updates ($100+).

Note the Drian is not VGBA complaint.

The skimmer is original. Older. Likely due for update at re plaster stage ($1k+). Until then update the float , float o ring , weir , weighted basket , and maybe new lid ($300).

Working, poorly, sits in corner = Due for service, currenlty moving but internals / tires / are likely near expiration and due for service + wall adapter + hoses ($300+) note a new unit is $450 winter rate Amazon.

Due to poor water clarity (which may also be water / chemistry related) an element set is likely needed unless replaced in the past 1 year.

A new element set ($500), new pressure gauge (recommended) ($50), and painting the filter shell ($50) to avoid additional uv breakdown.

But in reality you can buy a high quality filter (35001 Aqua Star) for approx $700 and due to the condition of this low cost filter, I’d recommend replacement ($700+ install approx $600) over any service to this unit.

Working, there is only one leak in the pump lid o ring , recommend service ($50).

I would anticipate this pump working up to another 5 years.

A best option is the Pentair Superflo Vs ($1200) or a generic version is approx $600 on Amazon = like this pump.

Working on a prayer only, will expire any minute. Leaking at seal plate. Pump is approx $100 used or $500 new. Approx +$500 for install for hard plumbing vs current soft hoses.

Non GFCI , recommend adding a sub panel and GFCI s ($300 parts $350 electrician).

The equipment pad is heavily sun exposed recommend re plumbing new and fresh + re painting and re labeling the pad ($500+).
