Pool Drain & Restart Service in Fresno, CA

Sometimes the only fix is a fresh start. NTS Pool Services drains, cleans, and refills your pool, so you're working with clean water again.

When Chemicals Alone Can’t Fix Your Pool


There are situations where no amount of shocking, balancing, or algae treatment can bring a pool back to a safe, swimmable condition. When your water chemistry is too far gone—high TDS (total dissolved solids), extreme calcium buildup, severe algae that won't respond to treatment, or simply years of accumulated chemical imbalance—a full drain and restart is the most effective and often the most cost-efficient solution. NTS Pool Services handles the entire process for Fresno homeowners and commercial property owners: draining the pool safely, cleaning the shell, and refilling with fresh water so you're starting from a clean slate.

Industry guidelines recommend draining and refilling your pool every 3–5 years under normal conditions. In Fresno's hard water climate, it's often needed sooner. A drain and restart is the right call when:

Signs Your Pool Needs a Drain and Restart

High TDS levels


Total dissolved solids above 2,500 ppm make it nearly impossible to maintain proper water chemistry, no matter how many chemicals you add.

Severe or persistent algae


Black algae and extreme blooms that don't respond to chemical treatment often require draining, scrubbing, and an acid or chlorine wash before refilling.

Extreme calcium hardness


Fresno's hard water causes calcium to build up over time. When levels are too high, scaling on surfaces and equipment becomes unavoidable.

Routine water replacement


Even well-maintained pools accumulate dissolved solids over time. A scheduled drain every 3–5 years is standard industry practice for long-term water quality.

Cyanuric acid overload


When stabilizer (CYA) levels exceed 100 ppm, chlorine becomes ineffective, a condition sometimes called "chlorine lock" that only a drain can fix.

Purchasing a new home


Inheriting someone else's pool history is a gamble. A fresh drain and restart gives you a clean, verified starting point you can trust.

What’s Included in Our Drain & Restart Service

Every drain and restart is performed by a highly trained NTS Pool Services technician following industry-standard procedures to protect your pool shell, equipment, and surrounding property.

Pre-drain inspection


We assess your pool's condition, surface type, and equipment before draining to determine the right cleaning approach and protect your investment.

Acid or chlorine wash (if needed)


For pools with heavy staining, deep-set algae, or significant calcium deposits, an acid or chlorine wash is applied to restore the pool surface before refilling.

Safe, controlled draining


Water is pumped out safely and directed to appropriate drainage to comply with local Fresno water disposal regulations.

Refill & startup chemistry


Once refilled, we test and balance all chemical levels—pH, alkalinity, calcium hardness, stabilizer, and sanitizer—for a safe, properly balanced fresh start.

Pool shell cleaning


The exposed pool surface is scrubbed to remove scale, staining, and any remaining algae, leaving a clean surface ready for fresh water.

Equipment check


Pump, filter, and circulation equipment are checked before and after the refill to confirm everything is running correctly with the new water.

Important: pools should never be left empty for extended periods, especially in Fresno's summer heat. An empty pool shell can crack, blister, or pop out of the ground due to hydrostatic pressure. Our team works efficiently to minimize the time your pool is empty.

Why Fresno Pools Need Draining Sooner Than Most


Fresno's municipal water supply is notably hard—high in calcium and magnesium—which means dissolved solids accumulate in pool water faster than in softer water regions. Combined with intense UV exposure, long swim seasons, and high evaporation rates that concentrate chemicals faster, Fresno pool owners often find their water chemistry becomes unmanageable sooner than the national average. Many local pools benefit from a drain and restart every 2–3 years rather than the standard 5. If your water has been feeling rough on skin and eyes, leaving white scale on surfaces, or simply refusing to stay clear no matter what you add, it's probably time.

Start Fresh, Then Keep It That Way

A drain and restart gives you a perfect foundation: fresh water, balanced chemistry, and a clean pool shell. The best way to protect that investment is consistent weekly maintenance. NTS Pool Services' weekly pool service keeps your water chemistry in check year-round so your pool never gets to the point of needing another drain. Many customers pair their drain and restart with a weekly service plan for exactly this reason.
