Draining and refilling a spa is one of the most requested—and most profitable—services a pool and spa business can offer. Most owners avoid it because they don't know pricing, labor expectations, or how to communicate value to customers who expect it to cost nothing.
Why Spa Drain & Refill Is Gold for Your Business
Customers call for drain and refill work 2–4 times per year on average, depending on climate and usage. That's recurring revenue with minimal competition in many markets. Unlike equipment repairs that require inventory and certifications, this service relies on time, delivery logistics, and water disposal—barriers that protect your margins once you set up the infrastructure.
A single spa drain and refill generates $200–$600+ in gross revenue per job. Multiply that by consistent bookings, and you're looking at serious cash flow that scales faster than filter replacements or chemical balancing.
Pricing Structure That Sticks
Gallonage matters. Standard residential spas hold 300–600 gallons. A larger hot tub can exceed 800 gallons. Your first step is knowing the capacity and charge accordingly.
Most successful spa service companies use tiered pricing:
- Small spas (under 400 gallons): $250–$350
- Medium spas (400–700 gallons): $350–$500
- Large spas (700+ gallons): $500–$700
These ranges account for labor (draining, flushing lines, refilling), water disposal fees (often $0.50–$1.50 per 100 gallons in municipalities with disposal regulations), and delivery time. If you're using a truck with a water tank, add fuel costs to your baseline.
Don't undercut yourself. New companies often price at $150–$200 to win jobs. You'll burn out your team and damage market perception. Residential customers expect to pay $300 minimum because they understand the service complexity and logistics involved.
Operational Checkpoints
Water disposal is non-negotiable. Never dump spa water into storm drains without checking local codes. Many municipalities have stormwater runoff restrictions, especially if the water contains chlorine or bromine. Partner with a disposal facility or build disposal into your truck setup. This compliance step alone justifies higher pricing and protects your business from fines.
Labor timing: A straightforward drain and refill takes 45 minutes to 2 hours depending on hose runs, water source access, and whether you're flushing equipment. If the spa needs jet line flushing or chemical adjustment post-refill, add another 30 minutes. Build realistic schedules so you don't double-book or rush jobs.
Seasonal demand: Winter in cold climates drives drain work (freeze prevention). Summer in hot climates increases refill requests (water loss and chemical imbalance). Plan your crew and truck availability around these cycles.
Add-On Services to Increase Ticket Value
Once you're on-site for a drain and refill, offer complementary services:
- Jet line flushing ($50–$100 additional)
- Filter cleaning or inspection ($30–$75)
- Shell or acrylic deep clean ($75–$150)
- Starting chemistry after refill ($25–$50)
Customers already expect you there. These upsells feel natural and boost your average job value to $400–$750.
Getting Found and Booking Consistently
Your market probably has 15–30 pool and spa companies competing for attention. Listing your drain and refill service on platforms where homeowners actively search—like Mercoly—puts you in front of leads ready to book. You can showcase your service packages, upload photos of completed work, and collect reviews that build trust faster than Google alone.
Setting Boundaries and Protecting Margins
Document your service in a one-page quote template. Include water source requirements (access to hose hookup), disposal fees if applicable, and what's included (refill, basic flushing, startup). This prevents scope creep and misunderstandings.
Require a 48-hour cancellation window or charge a booking fee. Customers respect clear policies.
Frequently Asked Questions
Q: Should I charge extra if the customer has no nearby water access? Yes. If you're running a hose more than 75 feet or using a water tanker, add $50–$100 to cover logistics and setup time.
Q: Can I reuse the drained water for landscaping? Only if municipal codes allow it and the water is chlorine-free. Most spa water isn't reusable due to chemical content, so confirm locally before promoting this option.
Q: What's the best frequency to recommend drain and refills to customers? Most manufacturers recommend twice yearly for regular-use spas, quarterly for heavy use. Build these expectations into your service plans.
