ServicesPool Drain and Refill

Pool Drain and Refill in Chandler

When your water stops responding to chemicals, a fresh start fixes what weekly balancing can't. We drain to the sewer cleanout as local rules require, protect the plaster while the pool is empty and refill with water we balance carefully so your surfaces start clean.

When a Drain and Refill Is the Right Call

Every time pool water evaporates, the minerals stay behind. Add sunscreen, dust, stabilizer and chemicals week after week, and total dissolved solids climb until the water turns dull, chlorine stops holding and white scale builds at the waterline. At that point, more chemicals only add to the problem. Draining and starting fresh is the honest fix.

We test first and tell you plainly whether you need it. Sometimes a partial drain will do. If the water still has life in it, we will say so and suggest weekly pool cleaning or a filter cleaning instead.

The part most people don't think about is where the water goes. Pool water can't simply run into the street or a storm drain. It goes to your home's sewer cleanout, with chlorine brought down first. We handle that the right way so you never have to wonder whether your drain day broke a city rule.

What Your Drain and Refill Includes

Water testing before we start
We check calcium hardness, cyanuric acid and dissolved solids so the decision is based on numbers, not a guess.
Compliant discharge
We let chlorine drop to a safe level, check pH and pump to the sanitary sewer cleanout. We confirm current city discharge rules before the pump runs, and if your HOA has its own requirements we work within them.
Care for the empty shell
An empty pool in strong sun can crack or delaminate plaster. We keep the dry time short, open the hydrostatic relief valve when appropriate and watch the surface while it is exposed.
Cleanup while it's empty
We clear debris, scrub stains and look over the tile line, lights and fittings. If you want a deeper reset, this is the best moment for acid washes or calcium removal and tile cleaning.
Fresh-water startup
As the pool refills we add a metal sequestrant, then bring calcium, alkalinity, pH and stabilizer into range so your plaster and equipment start on good terms.

Signs Your Pool Water Needs Replacing

  • Chlorine won't hold

    You add chlorine and the reading drops within a day or two. High stabilizer often locks it up, and only fresh water brings it down.

  • Cloudy water that stays cloudy

    The filter runs clean and the chemistry looks fine, yet the water has a hazy, flat look that never clears.

  • Scale coming back fast

    White crust returns at the tile line weeks after it was cleaned. That points to calcium levels the water can no longer hold.

  • It's been years

    With our hard water, most pools need fresh water every few years. If you can't remember the last time, it is worth a test.

  • Surface work is planned

    Acid washes, tile cleaning and some repairs need the pool empty, so draining comes first.

What Affects the Price

Most drain and refill jobs follow the same steps, but a few things change the time and materials involved. We walk you through them during your free quote by phone and put every line in writing before we start, so the price you hear is the price you pay.

Pool size and depth

More gallons means longer pumping, a longer fill and more startup chemicals.

Access to the cleanout

A cleanout close to the pool is quick. A long hose run around the house or a buried cleanout takes extra setup.

Surface condition

Heavy staining or scale may call for added cleaning or an acid wash while the pool is empty.

Repairs found when empty

If we spot a cracked fitting or failed light gasket, we quote it separately so you can decide. Our ROC licensed work on repairs follows manufacturer warranties, between 1-2 years.

How Drain Day Goes

  1. 1

    Test and plan

    We test your water, talk through timing and explain what the city expects for discharge. Cooler months are kindest to an empty pool, so we usually suggest fall through spring.

  2. 2

    Prepare and drain

    We shut down and protect the equipment, confirm the chlorine and pH are ready for discharge and run the pump to the sewer cleanout. We stay with it and keep the hose secure.

  3. 3

    Clean and inspect

    With the shell exposed we clean the surface and look for cracks, loose tile or worn fittings. You get a plain account of anything we find, with photos, before any extra work is discussed.

  4. 4

    Refill and balance

    We start the fill right away so the plaster isn't left baking. When the water reaches the skimmer we restart the equipment and balance the new water over the next visits.

Drain and Refill Questions

Can't I just drain my pool into the street?

No. Local rules generally keep pool water out of streets, gutters and storm drains, because that water flows untreated to washes and retention areas. It belongs in the sanitary sewer through your property's cleanout. We set that up and lower the chlorine first.

Is it safe to drain a pool in the summer?

It can be done, but it is riskier. Plaster exposed to intense sun can crack or peel, so we keep summer drains short and prefer cooler months whenever you have the choice.

How long will my pool be empty?

Usually just long enough to drain, clean and inspect. The refill starts as soon as that work is done. Filling from a garden hose takes a while, so expect the water to rise over the rest of the day and into the night.

Will the new water stain my plaster?

Fresh fill water carries metals and minerals that can stain if left alone. We add a sequestrant during the fill and balance calcium and pH quickly, which is why startup is part of the job, not an extra.

What if you find a problem while the pool is empty?

We show you photos and explain what we found in plain terms. A cracked fitting or worn light gasket is easiest to fix now, and we can handle that pool repair for you. You will know the scope and cost before we touch anything.
