New Pool

[BMerrill]

Having a fiberglass pool installed in about 20 weeks. Leisure Pinnacle 40, 17890 gallons, using totally Hayward equipment, cartridge filter, no heater at this time, but plumbing will be such one can be added in the future. .

First question, Pool equipment location:
Anything recommended to pipe, add, use, etc. where the equipment is located? Will be adding a flow meter, water temp sensor, air temp sensor. Have seen a few builds where a hose bib is adding in the piping, maybe a way to pump off water.

Welcome to the forum!
Most important items are to have a VS pump and SaltWater Chlorine Generator. Not sure what your flow meter will be used for but if you would like it, get it. The water temp sensor is needed if you will have a heater and the air temp sensor is standard for most automation systems. Be sure you have a 110V GFCI plug within 10' of the pool to plug your robot into for cleaning the pool.
I suggest you read ABC's of Pool Water Chemistry.

Thank you for the welcome.
The pump will be the Tristar 900 VSP, and yes, a salt system.

Flow meter will be used to finetune the pump speeds to achieve the recommended (3) water turnovers per day at a cost efficient means and using high, medium, and low flowrates.
I'm a technical type person.

See if my assumptions and calculations are correct in this example.

One Turnover filters about 63% of the water, 2 about 86% and 3 about 95%.
Need to stay above the minimum 11 gal/min flow rate for the salt system.
Pool has 17,890 gallons x 3 =53670 gallons minimum to filtered each day.
My KWh rate is $0.125

Pump will run 24 hours a day.
Flow rate and cost per hour. (flow rates at rpms and watts are from Swimming Pool Steve).

@ 1000 rpm =2.7ft/sec in 2" pipe = 28gpm: one turnover takes 10h 39m, 140 watts= $0.017/hr.
@ 2000 rpm =6.0ft/sec in 2" pipe = 55gpm: one turnover takes 5h 25m, 525 watts= $0.066/hr.
@ 3000 rpm =8.4ft/sec in 2" pipe = 86gpm: one turnover takes 3h 28m, 1530 watts= $0.191/hr.
@ 3450 rpm =11.2ft/sec in 2" pipe = 100gpm: one turnover takes 2h 59m, 2300 watts= $0.288/hr.

Pump will need to run at high, medium, and low flow rates during the day.
Possible schedule:
3 hours @ 3000 rpm = 15,480gal = $0.574/day
6 hours @ 2000 rpm = 19,800gal = $0.394/day
15hours @ 1000 rpm = 25,200gal = $0.263/day
This schedule will filter 60,480gal/day at a cost of $1.23 or about $37 a month.

recommended (3) water turnovers per day

Turnover is a myth. Chemistry keeps your water clean and clear, the filter simply removes things that fall into the pool.

Understand the myth of turnover rates.

.....but you had fun doing all that math, admit it!
Put the pool equipment in a spot that is out of view, or that can be hidden later by some plantings or camouflage. Yet easy to work in, you'll want a light in the space for night time adjustments.
Also you want them to add a water spigot nearby so you can water plants near the pool, or add water to the pool, or wash off the pool deck of spilled ice cream..... just really handy to have.
Also an outlet near the pool or equipment pad intended for use for a pool robot to clean the pool. A charge your phone......

Just some ideas.

Welcome to TFP. What color did you choose? I have a similar pool going in from Imagine Pools called Illusion. I too am going with the 40. I'm pretty excited! I'm going Storm Grey.

Crystal blue. Lighter color pools work better with lights.
