Hot Tub – Heating problems / Low pressure issues?



To properly heat and maintain the water in your hot tub, efficient circulation is needed throughout the system. With excellent water flow, your spa will heat up quicker and take full advantage of the equipment inside the tub. Stagnant water allows for bacteria to build up and contaminate your spa which would require excess chemicals and reduce the quality of your water.

Is the topside control panel displaying HH or dr? There may be an airlock in the system or dirty or blocked filters reducing flow to pump.

To ensure that your spa maintains its circulation, follow these tips:

  • Be sure to keep your water level topped off above the highest jet to keep your water flowing.
  • When filling up your tub with water, try placing your hose inside the filter to reduce the chance of air bubbles being created
  • If you notice that you aren’t receiving pressure from a specific jet, the jet may be clogged with something. Remove it by twisting it counter-clockwise and clear it out.
  • A clogged filter can reduce the water circulation, be sure to keep them clean and change them every 4-6 months.
  • Low flow could also be caused by failing circulation pump or low speed pump.

Efficient water flow is crucial for the upkeep of your hot tub, and ensures that you receive the best experience from your spa.
