Pool Equipment Pad Replacement Cost (The Colony, TX)

The equipment pad is the part of your pool you never think about — until something on it fails and you realize that everything keeping your Colony pool alive sits on a 4×6 foot concrete slab behind the fence. The pump, the filter, the heater, the salt cell, the automation controller, the electrical sub-panel, the plumbing unions — all of it lives on the equipment pad, exposed to weather, humidity from Lewisville Lake, and the cumulative stress of running 8-12 hours per day for 10-20 years.

When a single piece of equipment fails, you replace it. When multiple components fail within a year or two of each other — common in Colony pools built in the 2000s and early 2010s where everything is aging simultaneously — a full equipment pad replacement becomes the more practical and cost-effective option.

For homeowners in Austin Waters, Stewart Peninsula, and The Tribute, here's what a full pad replacement involves, what it costs, and how to decide between replacing individual components versus rebuilding the entire pad.

What "Equipment Pad Replacement" Actually Means

A full equipment pad replacement means removing all existing pool equipment and replacing it with new components — typically upgrading from the original builder-grade equipment to modern, energy-efficient alternatives. The concrete pad itself usually stays (unless it's cracked or sinking), but everything on it is new.

Components typically included in a full pad replacement:

Pool pump (variable speed)
Filter (cartridge, sand, or DE — sized appropriately for the pool)
Heater (gas or heat pump — if the pool has one)
Salt chlorine generator (if upgrading to or already using saltwater)
Automation controller (Pentair IntelliCenter, Hayward OmniLogic, or Jandy iAquaLink)
Electrical sub-panel and GFCI protection
All plumbing connections (PVC unions, valves, fittings)
Equipment bonding and grounding connections
New union fittings for easy future service access

Component-by-Component Cost Breakdown

Variable Speed Pump

Cost: $1,000-1,600 installed

The pump is the heart of the system and the component where the upgrade from old to new delivers the most financial value. Replacing a 15-year-old single-speed pump with a variable speed pump saves $500-800/year in electricity — the pump pays for itself in under 2 years.

Recommended models for Colony pools:

Pentair IntelliFlo VSF: $1,200-1,600. Premium option with built-in flow sensor. Best for pools with spa combos or complex plumbing.
Hayward Super Pump VS: $800-1,200. Budget-friendly option. Reliable, simpler programming. Best for straightforward pool-only installations.

For a detailed comparison, see our guide on Pentair vs Hayward equipment.

Filter

Cost: $400-1,000 installed

Options:

Cartridge filter: $400-800. Simplest maintenance, no backwash line needed.
Sand filter: $300-600 plus sand media. Lowest maintenance, requires backwash discharge.
DE filter: $500-1,000. Finest filtration, most maintenance.

Sizing matters: The original builder may have installed an undersized filter to save cost. When replacing, size the filter for your pool's volume and pump flow rate — not just matching the old filter's size. An oversized filter runs at lower pressure, requires less frequent cleaning, and provides better filtration.

Gas Heater

Cost: $2,000-3,500 installed

If your pool has a gas heater and you want to continue heating, the replacement cost depends on the BTU rating:

200,000 BTU (up to 15,000 gallons): $1,500-2,200 for the unit
300,000 BTU (up to 20,000 gallons): $2,000-2,800
400,000 BTU (up to 30,000 gallons): $2,500-3,500

Add $500-1,000 for installation labor, gas line connection, and plumbing.

Upgrade option: If the existing gas line can be repurposed or extended, switching to a heat pump ($3,000-5,000 installed) provides dramatically lower operating costs for homeowners who heat regularly. See our guide on gas heater vs heat pump.

Salt Chlorine Generator

Cost: $800-1,400 installed (cell + control board)

If you're on a salt system, the cell and control board are replaced as a set during a full pad rebuild. If you're converting from traditional chlorine to saltwater as part of the rebuild, add $50-100 for the initial salt charge and $100-300 for any additional plumbing modifications.

Sizing recommendation for Colony pools: Oversize the cell. Colony's humidity and moderate calcium levels stress salt cells. A cell rated for 40,000 gallons on a 20,000-gallon pool runs at 40-50% output, generating less scaling stress and extending cell life from 3-4 years to 5-6 years.

Automation System

Cost: $1,500-3,000 installed

Automation is the upgrade most Colony homeowners add during a full pad replacement — and the one they say they should have had all along. An automation system lets you control the pump speed, heater, lights, salt cell, and water features from your phone.

Systems:

Pentair IntelliCenter: $1,800-2,500. Best integration with Pentair equipment. User-friendly app.
Hayward OmniLogic: $2,000-3,000. Best integration with Hayward equipment. Powerful but complex interface.
Jandy iAquaLink: $1,500-2,200. Best integration with Jandy equipment. Solid mid-range option.

Important: Match the automation brand to the equipment brand. Pentair automation with Pentair pump and salt cell. Hayward automation with Hayward equipment. Cross-brand automation works but with limited integration.

Electrical Work

Cost: $500-1,500

A full pad replacement typically includes:

New sub-panel or breaker upgrades to accommodate modern equipment (VSP and automation draw different loads than old single-speed setups)
Updated GFCI protection (if the existing GFCIs are original and past their 10-15 year lifespan)
Refreshed bonding connections (critical in Colony's humid environment where corrosion degrades bonding conductors)
New grounding connections

For Colony pools specifically, the humidity factor makes electrical work more important during a pad replacement than in drier inland cities. Corroded bonding connections, degraded GFCI devices, and moisture-damaged electrical components are common findings during pad teardowns.

Plumbing

Cost: $300-800

All PVC connections, unions, valves, and fittings at the equipment pad are replaced during a full pad rebuild. This eliminates aging glue joints, cracked unions, and leaking valve seals that have developed over 15-20 years.

Key detail: Install union fittings on both sides of every major component (pump, filter, heater, salt cell). Unions allow any component to be disconnected for service or replacement without cutting the plumbing. This saves significant labor cost on every future repair.

Total Cost: Full Equipment Pad Replacement

Component	Cost Range
Variable speed pump	$1,000-1,600
Filter	$400-1,000
Gas heater	$2,000-3,500
Salt chlorine generator	$800-1,400
Automation system	$1,500-3,000
Electrical work	$500-1,500
Plumbing	$300-800
Total (all components)	$6,500-12,800
Total (no heater, no automation)	$2,500-4,800

The realistic range for most Colony pool pad replacements: $5,000-9,000. This includes a VSP, filter, salt cell, basic electrical updates, and new plumbing — without a heater or full automation system. Adding a heater pushes toward $8,000-12,000. Adding automation pushes toward $10,000-13,000.

When to Replace the Whole Pad vs Individual Components

Replace Everything If:

Three or more components are over 10 years old. If the pump, heater, and filter are all original equipment from a 2012 build, replacing just the pump today means you'll be replacing the heater next year and the filter the year after. Three separate service calls, three separate mobilization fees, three separate plumbing disruptions. Replacing everything at once costs less total than replacing components one at a time over 3 years.

The electrical infrastructure is outdated. If the sub-panel, GFCIs, bonding, and grounding are all original and showing age, a pad replacement is the opportunity to bring everything up to current code and safety standards.

You're upgrading from single-speed to variable-speed. A VSP upgrade often triggers electrical changes (different breaker, different wiring), plumbing changes (different fitting sizes), and automation additions. If the rest of the pad is old, doing it all at once makes sense.

You want to change the pool's ecosystem. Going from a Hayward pad to an all-Pentair setup, or converting from traditional chlorine to saltwater, or adding automation that integrates with new equipment — these systemic changes are most efficient as a complete pad replacement.

Replace Individually If:

Only one component has failed and the rest are in good condition (under 8 years old, no signs of wear or failure).

Budget is tight. A $1,200 pump replacement is manageable now; a $9,000 full pad isn't. Replace the failed component, plan for the rest, and budget accordingly.

The failed component is the heater and the rest of the pad is relatively new. Heaters fail independently of pumps and filters — a heater replacement at year 8 doesn't mean the pump (also at year 8) is about to fail.

The Colony-Specific Considerations

Humidity and Corrosion

Colony's proximity to Lewisville Lake means equipment pad components corrode faster than in inland cities. During a pad replacement, inspect:

Sub-panel bus bars and breakers for oxidation
Bonding wire connections for green corrosion (copper oxidation)
Union fittings and valve stems for mineral buildup and corrosion
Motor housing bolts for rust

Replace any corroded components during the rebuild rather than leaving them for future failure.

Equipment Pad Drainage

Colony's higher rainfall and humidity mean the equipment pad stays wet more often than in drier cities. During a pad replacement, ensure the concrete pad slopes slightly away from the equipment (1/4 inch per foot is sufficient) so water drains rather than pooling around motor bases and electrical connections.

If the existing pad is flat or slopes toward the equipment, consider having a thin concrete cap poured with proper drainage slope — $200-400 and prevents years of moisture damage to new equipment.

Noise Considerations

Colony's newer neighborhoods have homes relatively close together. A full pad replacement is the opportunity to minimize pump noise — choosing a quiet VSP (Pentair IntelliFlo is notably quieter than most competitors) and ensuring the motor is mounted on vibration-dampening pads. Neighbors notice the difference between a 15-year-old single-speed pump screaming at 3,450 RPM and a modern VSP humming at 1,800 RPM.

Financing and Timing

Best Time to Replace

October through February. Equipment suppliers and installers are less busy in the off-season. You may get better pricing, faster scheduling, and more attention from the installer. The pool isn't in active use during winter, so the 1-2 day installation doesn't cost you swimming time.

Worst time: June through August. Peak season demand means higher prices, longer wait times, and the loss of swimming days during installation.

Financing Options

Some pool equipment installers offer financing through third-party lenders (Synchrony, GreenSky, LightStream). Terms vary, but 12-24 month same-as-cash financing is common for equipment packages over $5,000. This spreads the $8,000-12,000 cost into manageable monthly payments while you immediately begin saving $500-800/year in electricity from the VSP upgrade.
