Water that will not balance
High stabilizer, high calcium and high dissolved solids that keep chlorine from working and keep scale forming. Fresh water resets all three.
Pool Acid Wash and Drain and Refill in Tucson
When years of hard water and chlorine tabs make the water impossible to balance, or stains have set into the plaster, a fresh start is the fix. We drain, clean, refill and start the pool up properly.
- Drain and refill, with or without an acid wash
- Drained to the rules for your jurisdiction
- Surface checked before any acid touches it
- Full chemical start-up after the refill
Tucson water builds up until it cannot be balanced
Pool water in Tucson does not stay the same water. The sun and dry air evaporate a lot of it, and every top off from the hose brings in more of Tucson's hard water. The water leaves, the minerals stay. Over a few years calcium climbs, total dissolved solids climb, and if the pool has been run on chlorine tabs, stabilizer climbs too, until chlorine barely works and scale keeps forming on the tile and in the equipment.
At that point no amount of chemicals will fix it, because the problem is what is already in the water. The fix is to drain it and start again with fresh water. That is a drain and refill, and for many Tucson pools it is normal maintenance every few years rather than a repair.
An acid wash is a separate step that can be done while the pool is empty. It strips a thin layer off the surface of existing plaster to remove stains and scale. It is useful, but it is not gentle, it is not right for every surface, and it is not a substitute for resurfacing. We look at the surface first and tell you whether an acid wash will help, whether a gentler cleaning is better, or whether the plaster is worn enough that it needs resurfacing, which is work we do not do.
What a fresh start fixes
Stains and scale on plaster
Organic stains from leaves and pods, and mineral scale from hard water, removed from existing plaster by an acid wash where the surface can take it.
A pool that has sat too long
A pool left stagnant in a vacant house, or one so far gone after a storm that draining is faster and cheaper than treating.
What a drain, wash and refill includes
Water and surface check
We test the water to confirm a drain is the right fix, and look over the surface to decide between an acid wash, a gentler cleaning, or neither.
Controlled drain
The pool drained with a submersible pump, with the water discharged the way local rules require for your property. Where and how pool water can be discharged is regulated locally, and we follow the rules for your jurisdiction.
Acid wash or clean, if chosen
On plaster that can take it, a controlled acid wash, worked section by section and neutralized afterward. Tile line scale removed while the pool is empty.
Refill and start-up
The pool refilled, the equipment restarted, and the water balanced from scratch, with extra attention in the first weeks while new plaster surfaces settle and fresh water comes into range.
How a drain and refill works
Test and inspect
We test the water and look at the surface, then recommend a drain and refill, an acid wash, both, or neither, with the reason.
Pick the timing
Spring and fall are best. Draining in the summer heat exposes the surface to harsh sun, and we avoid leaving a pool empty longer than it has to be.
Drain to local rules
The pool drained with the discharge handled the way your jurisdiction requires.
Clean or acid wash
The surface cleaned or acid washed as agreed, and the tile line descaled while it is dry.
Refill
Fresh water added, with the equipment off until the level is safe for the skimmer and pump.
Start-up and balance
The water balanced from fresh, sanitizer brought up, and the pool checked over the following weeks.
Why Tucson owners trust us to empty their pool
We do not drain a pool that does not need it. If your water can be balanced, we will tell you, and save you the refill.
We do not acid wash a surface that cannot take it. Every acid wash removes a little plaster. On thin, worn or older surfaces, that can do more harm than good. We look first and recommend the gentler option when it fits, and we say plainly when the surface is past cleaning.
And we treat the refill as a start-up, not an afterthought. Fresh water in Tucson still needs to be balanced carefully, and the first few weeks after a refill set the tone for the next few years.
Water that will not balance, or stains that will not budge?
Tell us what you are seeing. We will test the water, look at the surface and tell you whether a drain, a wash, or neither is the right call.
Acid wash and drain questions
How much does it cost to acid wash a pool in Arizona?
The price depends on the size of the pool, whether it is a drain and refill only or a drain with an acid wash, how much scale and staining there is, and the cost of the water to refill it. We quote a single written price after looking at the pool.
Can I acid wash my pool without draining it?
Not a true acid wash, which is done on a dry, empty surface. Some stains and scale can be treated with the water in, using stain treatments and careful pH control, and waterline scale on tile can often be removed without draining. A full acid wash needs the pool empty.
How many times can a pool be acid washed?
Only a limited number of times over the life of a plaster surface, because each wash removes a thin layer. Many pools only take a few before the surface becomes rough or thin. That is why we look at the surface first and use the gentlest method that will do the job.
Does acid wash damage a pool?
Done badly or too often, yes. Acid removes plaster, and on a thin or worn surface it can expose rough patches or leave the finish blotchy. Done carefully on a surface that can take it, it removes stains and scale without harm. It is not right for every pool, and it is not safe for some surfaces at all.
Can I acid wash a pool myself?
It is possible, but it is not a job to learn on. It involves strong acid, fumes, protective gear, neutralizing the residue and disposing of it correctly, and it is easy to etch the plaster or burn the surface. A mistake can cost more than the job. Most owners are better off having it done.
How long should it take to acid wash a pool?
The draining is usually the longest part and depends on the size of the pool and the pump. The wash itself is typically a day's work for an average residential pool, followed by the refill and start-up. We give you the expected timeline before we start.
