Just Bought a House With a Pool? Start Here

Somewhere between closing on the house and unpacking the last box, it hits you: there's a pool in the backyard now, and nobody handed you a manual. That's normal. Most previous owners hand over a garage code before they hand over a maintenance log. Here's the calm version of what to actually do in your first week, first month, and first season.

Week one: figure out what you have

Before you touch a single chemical, spend twenty minutes just looking. You're trying to answer four questions: what kind of pool is it, what's the equipment, is anything obviously broken, and is the water currently safe to swim in.

• Pool type: chlorine, saltwater, or something else? A saltwater pool has a salt chlorinator cell inline near the filter, usually a black cylindrical housing with two cables running to a control box.
• Surface: plaster (smooth, painted-looking), pebble (textured, speckled), vinyl liner (a single continuous sheet, seams visible), or fiberglass (glossy, molded, few or no seams).
• Equipment on the pad: pump (the one always running, has a motor and a basket you can open), filter (sand, cartridge, or DE, usually the largest tank-like object), and a heater if you have one (looks like a small furnace, often gas-fired).
• Obvious red flags: visible cracks in the surface, a pump making grinding or screeching noises, a filter pressure gauge pegged in the red, or water that's green, cloudy, or has a strong chemical smell.

Get one water test before you do anything else

You don't need to memorize pool chemistry to get started, you just need one baseline reading. A test strip from any hardware store will tell you the basics; a liquid test kit is more accurate but not required on day one. What you're looking for:

If your numbers are close to these ranges, you're in good shape and can move on to the equipment walkthrough below. If they're far off, that's still fine, it just means balancing the water is your first real task. Start with pH and total alkalinity before worrying about anything else; most other problems get easier to fix once those two are in range.

Learn the equipment before you learn the chemistry

New owners often go straight for chemical dosing calculators and skip the equipment walkthrough, but equipment problems are usually more expensive to ignore than chemistry problems. A pump that's about to fail or a filter that's never been backwashed will cause chemistry problems anyway, so it's worth five extra minutes.

• Find the pump timer or automation controller and figure out the current run schedule. Most pools need 8-12 hours of circulation a day, more in hot weather.
• Check the filter pressure gauge. Note the number when it's freshly cleaned; you'll backwash or clean it when the pressure climbs 8-10 PSI above that baseline.
• If there's a heater, don't worry about it yet unless you plan to use it immediately. Heaters are usually the last thing to troubleshoot.
• Ask the previous owner (or the listing agent) for any equipment manuals, warranty paperwork, or a service contract, even after closing. It costs nothing to ask and can save real money if something is still under warranty.

Set a maintenance rhythm, not a maintenance panic

The pool owners who struggle are usually the ones who either ignore the pool entirely or try to perfectly optimize it from day one. Neither works well. What works is a light, repeatable rhythm: a quick visual check most days, a real water test once a week, and a slightly closer look once a month.

• Most days: skim the surface, empty the skimmer basket if it's full, glance at the water clarity.
• Weekly: test the water, adjust chemistry if needed, brush the walls and steps.
• Monthly: check the filter more closely, look over the equipment for leaks or unusual noises, review whether your maintenance schedule still matches the season.

This is exactly the kind of routine Skimmer is built to hold for you: it pre-loads a maintenance schedule for your pool type, tracks every water test and chemical dose, and reminds you before anything slips, so you're not relying on memory during your first season.

What to genuinely ignore for now

You don't need to research every possible pool problem in week one. Skip, for now: resurfacing timelines, whether to convert to saltwater, advanced water-balance indices like the Langelier Saturation Index, and any chemical you don't already own. Those matter eventually, not this week.
