ServicesPool Drain and Refill

Pool Drain and Refill in Guadalupe

When your water stops responding to chemicals, a fresh start is often the fix. We drain the pool to the right outlet, keep hoses and water off your patio and plants, and refill with water balanced from day one.

Why old pool water eventually has to go

Every time water evaporates from your pool, the minerals and chemical leftovers stay behind. Each top-off adds more. After a couple of years, calcium hardness, stabilizer and total dissolved solids climb high enough that chlorine works poorly, scale forms faster and the water looks dull no matter what you add.

A drain and refill resets all of that at once. It is usually needed every two to three years in our hard-water area, sooner if the pool sees heavy use or has been through a stubborn algae bloom.

We treat it as work at your home, not just a pool job. That means planning the hose route before the pump starts, protecting your pavers and planters, and leaving the deck rinsed and the equipment area clean when we finish.

What the drain and refill includes

Water testing first

We test hardness, stabilizer and dissolved solids before recommending anything. If a partial drain will do the job, we tell you so.

Draining to the proper outlet

Most cities in the area require pool water to go to the sewer cleanout, not the street or a neighbor's wall. We locate your cleanout and run the discharge hose there.

Protecting the shell

We open the hydrostatic relief valve in the main drain so groundwater pressure cannot push on an empty pool. We also keep the time the surface sits dry as short as possible, since bare plaster can crack or stain in the sun.

Cleaning the empty pool

Leaves, grit and the sludge that settles in the deep end come out by hand and get bagged, not hosed onto your landscaping. We rinse the walls, floor and steps before the refill begins.

Refill and start-up chemistry

Once the pool is full, we balance pH, alkalinity and calcium and add stabilizer and chlorine in the right order for fresh water. New water is soft, so this step protects plaster and tile grout from being etched.

Cleanup on the way out

Hoses get coiled and removed, the pump area is wiped down and the deck is rinsed. You should not find mud tracks, stray hose clamps or puddles where we worked.

Signs your pool needs fresh water

Chlorine will not hold
High stabilizer locks up chlorine, so you keep adding it and the water still turns hazy or grows algae. Dilution is the only real fix.
White scale keeps coming back
If the waterline crust returns weeks after a tile cleaning, the water itself is carrying too much calcium.
Cloudy water that will not clear
Balanced readings plus a running filter should give clear water. When it stays dull, high dissolved solids are a likely cause.
Stains or a recent green pool
Pools coming out of a Green to Clean Recovery, or ones due for an acid wash, often need to be drained anyway, so it makes sense to start over with clean water.
It has been three years or more
Even a well-kept pool builds up minerals over time. If you cannot remember the last refill, a water test will tell us.

How the day runs

  1. 1

    Quote and timing by phone

    We talk through your pool size, its surface and when you last drained it, then give you a free quote. We suggest the cooler months when possible, since draining in peak summer heat is hard on plaster.

  2. 2

    Set up and protect

    We place the submersible pump, lay mats under equipment and route hoses along the edges of walkways to the cleanout. Gates stay closed so pets stay safe.

  3. 3

    Drain and clean

    Most pools drain in several hours. While the last water comes out, we clear debris from the floor and rinse the shell, and we let you know if we spot cracks or loose tile worth a look.

  4. 4

    Refill

    We start the fill from your home's hose bib right away. Filling usually takes a day or more, and we make sure the hose is secured so it cannot slip and flood a bed.

  5. 5

    Balance and wrap up

    After the fill, we restart the pump and filter, add start-up chemicals and recheck readings. The work area is cleaned and you get a plain explanation of what to expect over the next week.

What affects the cost

Every pool is a little different, so we quote after a short conversation about yours. The price depends on how much water there is to move, what the shell needs while it is empty and how simple the setup is. We list what is included so there are no surprises later.

Pool size and depth
More gallons means a longer drain, a longer fill and more start-up chemicals.
Work done while it is empty
Adding an acid wash or calcium removal and tile cleaning changes the scope. It is often cheaper overall to do it now than to drain again later.
Access to the sewer cleanout
A long hose run, a cleanout across the yard or a tight side gate adds setup time.
Condition of the water
Very dirty or green water may need treatment before discharge, and heavy sludge takes longer to clear by hand.

Drain and refill questions

Can I just drain part of the pool instead?
Sometimes, yes. If your readings are only moderately high, replacing a third to half of the water can bring them back in range. We test first and recommend the smaller job if it will work.
Is it safe to leave my pool empty?
Only for a short time. An empty pool can be pushed up by groundwater, and bare plaster can crack in direct sun. That is why we open the relief valve and start refilling as soon as the cleaning is done.
Where does the water go?
To your home's sewer cleanout in most cases, which is what local rules generally require. We check the requirements for your city and keep water off the street, your neighbors' property and your landscaping.
Do I need to be home?
Not the whole time. We need gate access and an outside spigot, and it helps to talk briefly at the start so we know where the cleanout and any sprinkler lines are.
When can we swim again?
Usually once the pool is full and the chemistry is balanced, often a day or two after the refill finishes. We will tell you when the readings are safe.
