Hot Tub or Spa Losing Water? How to Find a Spa Leak in Murrieta

A spa or hot tub runs warm water, so it loses some water to steam and splashing. But if you top it off every few days, there may be a leak. Spa leaks often hide in the jets, the pump or the pipes under the deck. This guide explains how to tell if your spa is leaking, a simple test you can run and when to call. Our pool and spa leak detection team answers 24/7 at (951) 299-3473.

How much water should a spa lose?

A covered spa should lose only a little water over a few days. Warm water, an open cover, wind and splashing all raise the loss. If the level drops fast, the cover stays on and no one has used the spa, a leak is likely.

Murrieta's dry air and warm days speed up evaporation, so keep the cover on when the spa is not in use. That alone can cut down on refilling.

What are the signs of a spa leak?

Common signs are a water level that drops even with the cover on, wet ground or puddles near the spa or equipment, a pump that runs loud or pulls in air, damp wood or panels around a hot tub, and water stains on the deck. Rising water bills from refilling are another clue.

  • Water drips under the hot tub cabinet or around the pump
  • The heater shows errors or shuts off from low flow
  • Soggy soil or extra green grass near the spa
  • Cracks in the spa shell or loose tile at the waterline
  • The spa that shares a pool spills over less than it used to

How can I test my spa for a leak?

Run a simple two-day test. On day one, fill the spa to its normal level, turn the pump off and mark the water line with tape. Check it after 24 hours. On day two, refill, run the pump as usual and check again. If the level drops more with the pump on, the leak is likely in the pressure side plumbing. If it drops the same either way, look at the shell, lights and jets.

  1. Keep the cover on and do not use the spa during the test.
  2. Mark the water line with tape at the start of each day.
  3. Day one: pump off. Day two: pump on as usual.
  4. Measure the drop each day and write it down.
  5. Look for wet spots near the pump, heater and pipes.

If your spa is attached to a pool, also read our guide on pool leak or evaporation.

Where do spa leaks usually hide?

Common spots are the pump seal, the unions and fittings at the equipment, the heater, the jet bodies, the light housing and the buried lines between the spa and the equipment pad. In-ground spas can also leak through cracks in the shell or the spillway into the pool.

In a portable hot tub, take off the side panels and look with a flashlight for drips, white crust and wet foam. In-ground spa lines are underground, so they need a pressure test and listening equipment to find. Learn more in our guide to how leak detection works.

Can I keep using a leaking spa?

A small, slow leak is not usually an emergency, but it should be found soon. A leak near the equipment can damage the pump and heater, and water under the deck can wash out soil. If water is near electrical parts, turn off the spa breaker and do not use it.

A leaking spa also raises your water bill. See our high water bill guide for how to check.

Frequently asked questions

Can you find a spa leak without draining it?

In most cases, yes. Dye, pressure testing and listening equipment let us test with the spa full.

Why does my hot tub only leak when the jets are on?

When the jets and pump run, the plumbing is under pressure. A leak that only shows then is often in a jet, union, pump seal or pressure-side pipe.

Do you test spas that are attached to pools?

Yes. We test the spa, the spillway and the shared plumbing and equipment.

How long does a spa leak test take?

It depends on the spa and how many tests are needed. Many visits take a few hours. We explain the plan before we start.

Prices are approximate estimates for planning. Your final price depends on your property and is confirmed before work begins.
