Your first 30 days with a pool should start with documentation, not chemistry. Week one is an inventory of the equipment, week two is four water numbers and the pump schedule, week three is the filter and the equipment’s age, and week four is deciding who does the work.
The order matters because a pool is a slow system: a month of ordinary attention can’t break it, but a month of none in a North Texas summer can quietly ruin it. The CDC’s home pool guidance tells owners “it is your responsibility to regularly check the chlorine concentration and pH.” For a new owner, that means one real water test in week one and a baseline to measure everything after it against.
If you haven’t closed yet, checking a pool before you close on the house comes first, while you still have leverage. This article starts the day the keys change hands.
Week one: find out what you own
The week-one inventory pays off every time something goes wrong for the next decade.
Photograph the equipment pad
Photograph every box on the pad, and every label close enough to read the model and serial number. Sunlight bleaches those labels blank within a few years, and they’re what a technician, a warranty claim, or a parts counter will ask for. Put the photos somewhere you’ll find them again.
Then put a name to each component. Our guide to everything on the pad walks the loop in the order water travels it, which is the easiest way to make sense of it.
Find the four things you’ll need in a hurry
- The breaker that kills the pump, in the panel, labeled or not. Label it today.
- The valves at the pad, and which way they currently sit. Photograph them in their normal running position so you can put them back.
- The autofill and its shutoff, if the pool has one.
- The timer or controller, and specifically whether freeze protection is configured, which is the setting that matters most between December and February here.
Get one real water test
Get one real water test, not a strip. Take a sample from elbow depth away from the returns to a pool store for a free panel, or buy a drop-based kit. You want free chlorine, pH, total alkalinity, calcium hardness, and cyanuric acid (CYA), sold as stabilizer. Write the numbers down with the date, because this is your baseline and you’ll want it in three months.
Do not drain the pool to start fresh
Draining the pool to start fresh is a common instinct and the most expensive one in Collin County. Our expansive clay holds groundwater that pushes upward on an empty shell, and a drained plaster pool can lift or crack, which is a structural repair rather than a resurface. Exposed wet plaster also crazes within hours in real heat. Whatever is wrong with the water, there’s a way to fix it with the water still in it.
Week two: learn four numbers and set the pump
Pool chemistry comes in week two, and there’s less of it than the wall of products at the pool store suggests.
| Reading | Target | What it controls |
|---|---|---|
| Free chlorine | Read against your CYA: at least 7.5% of it, or 5% on salt | Whether the water is sanitized at all |
| pH | 7.4 to 7.6 | Whether chlorine works, and whether the water scales or corrodes |
| Total alkalinity | 80 to 120 ppm | How violently pH swings between doses |
| Cyanuric acid (CYA) | 30 to 50 chlorine, 60 to 80 salt | How much chlorine you need to hold |
The relationship between free chlorine and CYA catches many new owners. Chlorine is judged against your stabilizer level rather than an absolute number, so a pool reading 3 ppm of chlorine can be sanitized or unprotected depending on a number many owners haven’t tested. Why chlorine reads fine and the pool still goes green explains the ratio, and the chemistry guide covers all four with the order to correct them in.
Work out your volume, then set the schedule
Pool volume for a roughly rectangular pool is length times width times average depth in feet, times 7.5, in gallons. That number determines dosing, turnover, and every product label instruction you’ll read.
Then set the pump for one full turnover a day rather than for the eight-hour rule many people repeat. On a variable speed pump that usually means running longer at a low speed, which moves the same water for a fraction of the electricity because power draw falls with roughly the cube of speed. The North Texas run time guide has the arithmetic and the seasonal adjustments.
Week three: the first filter clean and the equipment inventory
Week three has two jobs, one physical and one financial.
Clean the filter, and note the clean pressure
Whatever the previous owner told you, assume the filter hasn’t been serviced recently. Tear it down, clean it according to its type, reassemble, and then write down the pressure gauge reading with everything clean. That number is your baseline forever: roughly 8 to 10 psi above it means it needs doing again. Sand, cartridge, and DE (diatomaceous earth) are serviced differently, which the filter comparison covers.
Age the equipment and build the reserve
Using the photographs from week one, work out roughly how old each component is. Then apply realistic lifespans: pumps 8 to 12 years, salt cells 3 to 6, cartridges 3 to 5, gas heaters 5 to 10, plaster 7 to 12. Divide each replacement cost by its remaining years and you have the monthly reserve the sale didn’t mention.
That reserve is the running cost of the asset you bought. Equipment lifespan in Texas heat and what it costs to own a pool in Collin County do the arithmetic in full.
Week four: decide what you’ll do
By week four you know the pool, the numbers, the schedule, and the likely bills. The last decision is who does the work, and it turns less on money than on July.
Doing it yourself is achievable and plenty of people enjoy it. The routine is roughly two to four hours a week in summer: skim, empty both baskets, brush including the waterline, vacuum or reposition the cleaner, test, dose, and glance at the pad. The chemicals cost real money at retail, and you’ll need somewhere safe to store them.
The failure mode isn’t choosing to do it yourself. It’s choosing to do it yourself in April, when the water is 68 degrees and the whole thing is pleasant, and then discovering in late July that you haven’t tested in three weeks. A Texas pool goes from clear to green in roughly two to three days once free chlorine reaches zero, and a recovery costs several times a monthly service rate. The DIY versus hiring comparison lays out both columns.
The middle option: split the work
You don’t have to choose between everything and nothing. Plenty of owners handle skimming, brushing, and basket duty themselves and buy chemistry and equipment monitoring, or run the pool themselves through the mild months and take service from May to September. Ask for the arrangement you want rather than the package on the page.
Two things to do before your first summer, whichever way you decide
Check the barrier
Check the pool barrier by walking the fence line. Gates should self-close and self-latch from any position, latches should be out of a small child’s reach, gaps under the fence should be minimal, and nothing climbable should be sitting beside it. For a private backyard pool in Texas the requirement comes from your city’s adopted building code rather than from the state statute many articles cite, and what applies to your backyard covers that. Ground movement over a winter regularly puts a gate out of alignment, so this is worth checking annually rather than once.
Set up chemical storage before you buy chemicals
Store pool chemicals somewhere cool, dry, ventilated, off the floor, out of the sun, and out of reach. Keep each product in its own labeled container with its own scoop, and keep chlorine physically separated from acid. Chlorine plus acid makes chlorine gas, cal hypo plus trichlor can start a fire, and both happen by accident rather than by experiment. Chemical safety and storage covers the rest in five minutes.
If you would rather start with somebody who knows the pool
An inherited pool is the situation an equipment inspection is designed for: someone ages the pad, reads the chemistry properly, and tells you what has one more season in it and what doesn’t. Pools are often neglected between listing and closing, and then the first job is a green pool recovery rather than a normal visit, and any company quoting you a standard monthly rate for that hasn’t looked at it.
After that, weekly service is published with its pricing and can be stopped anytime, so a new owner can try it for a season and stop.
If you have moved here from somewhere with a real winter, read the North Texas pool year next. Our calendar doesn’t look like the one you grew up with: nothing gets closed here, and that one difference is behind much of what surprises people in their first twelve months.
