How to soundproof the Lay-Z-Spa pump?

In this blog, we’ll look at several soundproofing strategies that you may use to reduce the noise of a Lay-Z-Spa pump so you can enjoy your garden and hot tub in peaceful bliss.

A hot tub is a great place to unwind and enjoy yourself. An engine that is a little too loud is the last thing anyone wants to deal with. It has the potential to destroy people’s moods and annoy them if there is no remedy in sight.

Fortunately, companies are devising ever-smarter ways to deal with a hot tub motor in general. Not only are motors becoming quieter, but there are now additional soundproofing options available for those who want to turn down the volume a little.

Most hot tubs produce noise levels of 41 to 67 dB in the air. The noise level is only 41 dB, which is about the same as a typical library, so this shouldn’t be an issue. 67db, on the other hand, is more like steady road noise or the sound of your vacuum cleaner running. It’s also a low-frequency hum, which might be more unpleasant to hear than louder, higher-frequency noises.

Also, keep in mind that even tiny sounds become considerably louder and travel further at night. Many tubs are programmed to heat and run filtration cycles overnight, amplifying the noise they create.

You should also be mindful that when in the tub, you will be conversing and probably listening to music, which will add to the noise level.

How to soundproof the Lay-Z-Spa pump?

If the sound of your hot tub is too loud for you, there are some things you can do to quiet it down. Here are some excellent and reasonably priced options for soundproofing the Lay-Z-Spa pump.

Why Reduce Lay-Z-Spa Noise?

A noisy hot tub is a problem if your children’s bedrooms face the rear garden and you prefer to relax in your tub after they go to bed. If the noise wakes them up, you won’t be able to relax for long.

The noise your tub creates may be audible to your neighbours, based on the scale of your garden. Some internet commenters claim to be able to hear it far louder than the tub’s owners. Soundproofing is an excellent choice if you don’t want to be a bother and maybe harm your relationship. This will prevent your delight from being ruined by the fear of annoyance from others.

Sitting in a hot tub with your partner, family, or friends can be a wonderfully sociable experience. It can ruin the pleasure if you have to constantly raise your voice to be heard over the pump and jets. It’s not ideal to have to choose between a friendly conversation and the relaxing massage your tub gives.

Use Insulation Mats

Insulation mats for hot tubs are fantastic! They accomplish two important tasks in one fell swoop: they maintain heat and reduce noise. As they’re composed of thick rubber, the vibrations and total noise that escapes the tub are reduced. This is especially handy if your hot tub is on a wooden deck or another non-concrete surface.

Insulation mats also do what they say they do: they insulate the hot tub. This reduces heat loss and, as a result, saves you money on power. They’ll also safeguard your hot tub from tiny scratches and other damage that could lead to significant problems.

While you might theoretically improvise improvised insulation, insulating mats for most hot tubs and Lay-Z-Spas are commercially available. They will often cost less than £150 and can be purchased through a third party or directly from the manufacturer.

Lay-Z-Spa Noise Reduction System

The Lay-Z-Spa company has developed a Noise reduction system that can be used with any of their hot tubs. It’s a stand-alone electrical gadget that’s designed to lessen pump noise when all of your jets are functioning. This option is standard on most new models, however, it can also be purchased separately for older models.

Fences and Blockages

Building a fence or planting shrubs around your Lay-Z-Spa is a simple option that needs little elbow sweat. Noise will be absorbed, seclusion will be provided, and wind will be blocked by the additional material surrounding it. I like this option because it comes with a lot of extra features that don’t cost an arm and a leg.

Optimise the Pump

It’s possible that the pump is louder than it should be if it’s not positioned right, is faulty, or has dirt and debris stuck inside it. There are a few things you can do to see whether they address the problems on your own.

The pump should be installed in the following location:

  • It should be placed on a hard, level surface. Move it if it isn’t already and see if it helps.
  • It is not recommended that the pump be put on any sharp surfaces, such as gravel.
  • Even if you don’t use an insulation pad, foam mats should always be placed beneath your pump to protect it and absorb part of the noise.
  • Avoid placing the pump against or close to any walls. If it’s already there, try moving it to see if the noise level improves.
  • Make sure your pump isn’t blocked or boxed in. You may have seen a method on our site for making a soundproof box, but if you want to try it here, the box must be much larger than the pump. The pump will overheat and perhaps break if it is too tiny. It’s also a good idea to carve some ventilation ports into the box’s sides.

To clear out debris, follow these steps to backwash the system:

  • To turn the pump off, press the On/Off button on the pump display.
  • Completely unplug your tub from the power source.
  • Inside the spa, place the stopper caps over the debris screens. Take out the pump.
  • Couplings A, B, and C must be unscrewed.
  • Flush water through the B coupling attached to the pump with a hose. It should be able to exit via the C coupler.
  • Allow two or three minutes for the water to run through your pump.
  • Reverse the process and run the hose so that the water enters through the C connection and exits through the B coupling.
  • Allow for a few more minutes of operation before removing the hose and reconnecting the pump to the couplings.

If the water sensors aren’t functioning properly, your tub may be working harder than it needs to. This is how you resolve the problem.

  • To turn the pump off, press the On/Off button on the pump display.
  • Completely unplug your tub from the power source.
  • Inside the spa, place the stopper caps over the debris screens. Take out the pump.
  • Firmly strike the pump’s side, and the sensor should return to its proper position.
  • Re-plug the pump after reconnecting it.

Last but not least, try bleeding the pump like you would your radiators. On the front of the pump, look for the bleeder screw. It’s commonly found directly beneath the hot tub’s pipe. Crank the tub on and turn the screw several times anti-clockwise with a screwdriver. Before screwing the bleeder shut, wait until the water starts to shoot out.


Since inflatable hot tubs lack an insulated covering to assist absorb sound, they can be louder when in use. Please keep the following crucial things in mind for optimal Lay-Z-Spa noise reduction:

  • Place your pump on foam protective pads and a hard, level surface. Place it away from any walls.
  • To reduce vibration noise, minimize heat loss, and prevent your tub from harm, use a rubber insulation mat.
  • If feasible, place your tub in an enclosed location surrounded by a fence or thick plants. This will prevent both sound and wind. Because of the added mass, your hot tub’s sounds will be muffled, and the tub will be sheltered from the elements and remain warmer.
  • If your pump is still making a lot of noise, you should conduct the above maintenance. If you’re still experiencing trouble, you might want to contact Lay-Z-Spa directly for assistance.

The motor bearings may be deteriorating if the noise is a screeching, high-pitched whine. Bearings can be replaced, or if the motor is really old (more than 5 years old), the hot tub motor should be replaced. Second, if the noise is low-pitched and growling, the pump may be running out of water.

Is it possible to leave Lay Z Spa outside in the winter?

If you leave your LayZSpa outside in the winter without using it and the temperature dips below 4°C, the water inside the pump may freeze, causing catastrophic damage. The quality of your water may decrease, and you may notice a buildup of unattractive mould.
