Troubleshooting Series – My Hot Tub Is Leaking

Marquis Crown Resort Hot Tub

If you think your hot tub is losing water, then it could mean you have a leak. Here’s how to be sure, and what you should do.

How Do You Know If Your Hot Tub Has a Leak?

if you spot pools of water forming around the base of your spa, then this could be the signs of a leak. Likewise, a rapidly dropping water level could indicate your spa is losing water from somewhere.

Small amounts of water gathering at the base of the hot tub could be from rain or condensation, so be sure to pay attention to the water level before worrying that you have a leak. To be sure, make a small erasable mark on the inside of the tub at the water line, leave it over night and check in the morning. If it hasn’t gone down, then there’s likely no leak and what you’re seeing is possibly just rain water pooling or condensation. The exception is when the leak only appears during use.

Sometimes, your tub may only leak when in use or when the pumps or waterfalls are on, depending on where the leaks are coming from. If this is the case, you’ll see a drop in water level after use, so also be sure to check for this as any leak can be exacerbated or only appear when under pressure.

How to Find the Source

If you suspect you have a leak, the first thing you need to do is turn off the spa. Do this as soon as possible. Regardless of the source of the leak, it’s best to contact your dealer to fix the issue, or replace a part where necessary. However, it’s worth trying to find the source of the leak before you contact them, as this will increase their chances of them being able to bring the right parts or equipment on the first call out.

NOTE: The purpose of locating the leak is so you can better inform your dealer or technician, so they can gather as much information as possible before a call out. Don’t try to fix the issue yourself, as tampering with any of the parts could void your warranty, and could be potentially life threatening.

Some possible sources of leaks are:

  • The pump: this is one of the first places you should check, as it’s the most common cause of leaks. In some cases, it may be a seal that’s the issue, in others a replacement pump may be the only option, but a professional should be able to advise.
  • The heater: it’s possible the leak is coming from the heater, in which case you’ll need to call a professional to replace it.
  • Pipes/jets/connections: if it’s not the pump or heater, then it’s possible the leak is coming from a broken seal around the pipes or jets.
  • The shell: inspect the shell for any cracks or damage, especially in the area close to where the leak appears to be.

What to Do?

Whether you’ve managed to locate the leak or not, you’ll need to call in the professionals. Get in touch with your dealer/whoever does your hot tub servicing and repairs, and give them as much information as you can about the issue and potential source. If possible, take photos or video of the leak and share as much information as you can.
