Spa & Hot Tub Leak Detection in Las Vegas
A hot tub that needs topping off every few days, or a damp cabinet under a portable spa, usually means a leaking union, jet body or heater fitting. We test built-in spas and portable hot tubs alike, isolate each component and find the leak so you can soak without refilling.

Tracking Down Spa and Hot Tub Leaks
Why does my hot tub keep losing water?
Steady water loss in a spa or hot tub usually comes from leaking pump or heater unions, worn jet gaskets, a cracked heater manifold or a drain valve that does not seal. Testing the equipment, shell and plumbing separately shows which part is leaking.
Spas run hotter and at higher pressure than pools, which is hard on gaskets, unions and jet fittings. In a Las Vegas backyard, sun and heat speed up that wear. Our spa leak detection covers both in-ground spas attached to pools and portable hot tubs with internal plumbing, using thermal imaging to spot warm water escaping around heater lines.
For built-in spas, we test the shell, spillover, jets and the plumbing shared with the pool, often alongside pool leak detection so both bodies of water are covered in one visit. Portable tubs get a component-by-component check of pumps, heaters and unions. If the water loss is also showing up on your bill, our high water bill investigation can confirm whether the spa is the only source.

Backyard spasWhere Spas and Hot Tubs Usually Leak
Most spa leaks come from a short list of parts that take the most heat and pressure.
Pump and heater unions
Loose or cracked unions drip inside the cabinet or at the equipment pad, sometimes near an underground line leak.
Jet bodies and gaskets
Worn gaskets let water seep behind the shell.
Heater manifolds
Heat cycling can crack heater fittings over time.
Spillover and shared lines
Built-in spas can leak where they connect to the pool plumbing.
Drain valves
Drain plugs and valves that do not seal fully.
Shell cracks
Hairline cracks in acrylic or plaster from heat and settling.

How We Find a Spa Leak
Measure water loss
We compare loss with jets on and off to narrow the search.
Inspect equipment
Pumps, heaters and unions are checked for drips.
Test the shell
Dye testing around jets, lights and fittings.
Pressure test lines
Buried or internal plumbing is isolated and tested, using acoustic equipment for underground lines.
Spa Leaks Found Fast
A leaking spa wastes heated water and chemicals. We focus on the parts most likely to fail so the visit is efficient and the answer is clear.

Spa & Hot Tub Leak FAQ
Why is my hot tub losing water?
Evaporation accounts for some loss, but steady drops usually come from leaking unions, jets, heater fittings or drain valves.
Can you find leaks in a portable hot tub?
Yes. We open the cabinet and test pumps, heaters, unions and internal plumbing.
Do you test spas attached to pools?
Yes. Built-in spas are tested together with the pool, including the spillover and shared lines.
Is a leaking spa expensive to fix?
Many spa leaks are simple fixes such as unions or gaskets. Finding the exact source keeps the repair small. Check your water loss first with our leak calculator.
How do I know it is not just evaporation?
If the water level drops faster with the jets off and the cover on, it is very likely a leak.
