Hot Tub Leak Detection & Repair

Slow leaks are the trickiest spa repair to nail down. Water moves, foam soaks it up, and the actual source can be six feet from where you see the drip. We find leaks others miss.

What this service covers

Spa leaks fall into three buckets: plumbing leaks at fittings or unions, equipment leaks at pumps and heaters, and shell leaks through cracks or jets. The diagnostic approach is different for each, and most home-DIY fixes only work when the leak is exactly where it looks like it is. We use pressure tests, dye traces, and direct inspection to find the source and fix it once.

  • Pressure testing of plumbing lines
  • Union, fitting, and slip-joint resealing
  • Pump seal and wet-end repair
  • Heater manifold and tube replacement
  • Jet body and o-ring replacement
  • Drain valve and weir leak repair
  • Shell crack repair on acrylic and rotomolded spas
  • Foam removal for cabinet leak access

Problems this service solves

If your spa is doing any of these, this is the right page.

Water level drops every few days

A classic slow leak. Could be plumbing, equipment, or shell — pressure testing isolates it.

Wet ground around the pad

Plumbing or shell-side leak. Where the water sits doesn't always match where it's coming from.

Damp foam under the cabinet

Means the leak is somewhere in the equipment bay. Foam removal exposes the real source.

Drip at a pump or heater

Mechanical seal, union, or heater manifold. Each has a specific repair path.

Leak only when jets are running

Pressure-side leak — usually a jet body, manifold, or a hairline crack in a plumbing line.

Leak only with heat on

Heater tube or heater union. Common as spas age and PVC contracts and expands.

Frequently asked questions

How long does leak detection take?

Most leak diagnoses are wrapped up in 1 to 2 hours using pressure tests and dye traces. Repair time depends on the source.

Can a hot tub shell crack be fixed?

Yes — acrylic and rotomolded shells can be repaired. The repair is permanent when done correctly, though cosmetic match isn't always perfect.

Do I need to drain the spa first?

Sometimes. For an equipment-bay leak we can usually keep it filled. For a shell or jet leak we drain to the level of the source.

Why didn't sealing additives work?

Liquid sealers only fill very small leaks and often clog filters and heaters in the process. We don't recommend them and don't use them.
