I am new here to the forum and owning a pool. We moved into a house with a 18,000 gallon or so pool which hadn't been used for 25 years (appx). It is an enclosed concrete pool with a fiberglass liner. Long story short, the previous owner (father in-law) used it one year and then never again for the last 25 years or so. We had some delamination issues repaired and are now tackling the mechanical systems. The mechanical system is in the void between the pool foundation and the foundation of our home. We reach it through and old basement window which was removed to access the pool equipment.
It has a Swimquip HRP sand filter, Swimquip XV VI pump, and Coates electric pool heater. I added some pictures FYI.
My questions are:
1) Should we start by just adding some water to pool and then starting pump to check for leaks? If so, how much water? Just enough to pull from the bottom drains? Should we have the sliding valve on backwash when we do this?
2) Or should we replace sand first since it has likely been in there for 25+ years. If this is the case, it looks like we have to remove all of the bolts on the middle of the casing to replace the sand. Anyone with tips on this? What to watch out for, so as not to break anything etc.
3). The sliding valve appears to be sticky, what can we lube this with? WD-40, pool lube?
4). Is there anything on the pump which needs to be lubed/checked before attempting start up?
5). Any other suggestions ?
I know lot's of questions, I hope you all have lots of answers.
