SPA LOSING WATER? POSSIBLE SPA LEAK
If your spa keeps losing water faster than normal, there may be a leak somewhere in the spa structure, plumbing, fittings, or spillover system.
Spa leaks are common because spas operate under high pressure, high heat, and constant circulation. Even a small leak can waste water, damage surrounding areas, and affect pool/spa performance over time.
WHY SPAS DEVELOP LEAKS
Spas have multiple components that can eventually fail due to heat, pressure, movement, and aging materials.
Common spa leak causes include:
- Cracked spa plumbing lines
- Leaking spa jets or fittings
- Spillover or overflow issues
- Structural cracks in the spa shell
- Light niche or conduit leaks
- Air line leaks
- Underground plumbing leaks near the spa
SIGNS YOUR SPA MAY HAVE A LEAK
Look for these common symptoms:
- Spa water level drops quickly
- Spa loses water while the pool stays normal
- Air bubbles or low jet pressure
- Wet areas near the spa or equipment
- Water level stabilizes at a certain height
- Autofill runs more often than normal
- You constantly need to refill the spa
QUICK CHECKS YOU CAN DO BEFORE CALLING A PRO
1) Mark the spa water level
Turn the system off and monitor the spa water level over 24 hours.
If the spa loses noticeable water while isolated, there may be a structural or plumbing leak.
2) Watch where the water stops
If the water repeatedly stabilizes at the same level, the leak is often located at or just below that elevation.

3) Check the spillover system
On attached spas, water can sometimes drain into the pool if:
- a check valve fails
- plumbing leaks occur
- the spillover system malfunctions
4) Perform the bucket test
This helps confirm whether you’re dealing with evaporation or an actual leak.

WHY SPA LEAKS SHOULD NOT BE IGNORED
Ignoring a spa leak can lead to:
- Higher water bills
- Wasted chemicals and heat
- Underground plumbing damage
- Structural cracking over time
- Equipment strain from constant refilling
Spa leaks also tend to worsen faster because of heat and pressure fluctuations.
HOW PROS CONFIRM A SPA LEAK
To pinpoint the source, pros may use:
- Dye testing around spa jets, fittings, and lights
- Pressure testing of spa plumbing lines
- Isolation testing between pool and spa systems
- Inspection of spillover/check valve systems
- Structural crack assessment
Once confirmed, we recommend the proper repair based on the actual source of the leak.
WHEN TO SCHEDULE LEAK DETECTION
Schedule professional pool and spa leak detection in Tampa if:
- Your spa loses water rapidly
- The spa drains into the pool when off
- The water level repeatedly stops at the same point
- You suspect underground spa plumbing issues
- You want the leak pinpointed before damage worsens
If you’re in Tampa and your spa keeps losing water, we can pinpoint the exact source quickly.

FREQUENTLY ASKED QUESTIONS
WHY IS MY SPA LOSING WATER BUT THE POOL ISN’T?
This often points to a spa-specific plumbing leak, fitting leak, spillover issue, or structural crack.
CAN A BAD CHECK VALVE DRAIN MY SPA?
Yes. A failed check valve can allow spa water to drain back into the pool when the system shuts off.
DO SPA JETS COMMONLY LEAK?
Yes. Spa jets, fittings, and surrounding seals are common leak locations due to heat and pressure.
DO YOU HAVE TO DRAIN THE SPA TO FIND THE LEAK?
Not always. Many leak detection methods can be performed without fully draining the spa.
CAN YOU CONFIRM THE EXACT SOURCE OF THE SPA LEAK?
Yes. With professional testing, we can determine whether the issue is structural, plumbing-related, or equipment-related.
