Hot Tub Pumps & Parts

Hot Tub Pumps & Parts FAQs

• What does a hot tub pump do?

  A hot tub pump is responsible for circulating water through the heater, jets, and filtration system. It ensures even heating, proper water flow, and strong jet pressure for a great hot tub experience.

• How do I know if my hot tub pump needs replacing?

  You may need a replacement hot tub pump if:

  • Your jets have low or no pressure.
  • The pump is making loud noises (grinding, humming, or squealing).
  • The pump is leaking water from the seals or fittings.
  • The motor won’t start or keeps tripping the breaker.
• What are the different types of hot tub pumps?

  There are two main types of pumps:

  • Circulation Pumps – Runs continuously at low speed to filter and heat the water.
  • Jet Pumps – Provides high-speed power to run the jets and massage system.

• How do I choose the right hot tub pump?

  To find the correct hot tub pump:

  • Check the voltage (usually 230V in the UK).
  • Match the horsepower (HP) to your existing pump.
  • Check the speed (single-speed or two-speed).
  • Measure the plumbing connections (e.g., 1.5” or 2”).
  • Check the frame size (48-frame or 56-frame).
• What are wet ends, and do I need to replace them?

  The wet end is the part of the pump that moves the water. If your pump motor is working but leaking or lacking pressure, you may only need a replacement wet end instead of a full pump.

• Why is my hot tub pump making a loud noise?

  Common causes of a noisy pump include:

  • Airlock in the pump – Try bleeding the air from the system.
  • Clogged filter or low water level – Check water flow.
  • Worn bearings or motor issues – The pump may need replacing.
• How long should a hot tub pump last?

  A well-maintained hot tub pump lasts 4-6 years. Regular cleaning, keeping water chemistry balanced, and checking for leaks can help extend its lifespan.

• Why is my hot tub pump running but not moving water?

  Possible causes include:

  • Blocked filter or plumbing – Check for debris.
  • Airlock – Bleed the air out of the system.
  • Broken impeller – The wet end may need replacing.
