Nutone CH515 Vacuum Hose Replacement Guide

Nutone CH515 Vacuum Hose Replacement Guide

What Kind of Hose Does the Nutone CH515 Use?

The Nutone CH515 requires a 1.5 inch diameter crushproof hose. The hose needs to be made of a durable PVC or vinyl material so it can withstand the suction power of the unit without collapsing. Many standard vacuum cleaner hoses are too thin and flexible to work properly with a central vacuum system.

Nutone recommends using their branded hoses for optimal performance and longevity. They manufacture 1.5 inch diameter hoses in 7 foot, 12 foot, and 20 foot lengths. The hoses have a crushproof blue vinyl exterior and a gray cloth interior liner. This construction prevents clogs and allows smooth airflow.

Where Can I Buy a Replacement Hose?

You have a few options when it comes to purchasing a new Nutone CH515 hose:

  • Direct from Nutone – You can order directly from the Nutone website or contact their customer support line. This ensures you receive an authentic OEM part.
  • Local vacuum specialty store – Check vacuum repair shops in your area. Many carry supplies for major brands like Nutone.
  • Online retailers – Search Amazon, eBay, or other online stores for Nutone central vacuum hoses. Compare prices carefully.
  • Big box hardware stores – Stores like Home Depot and Lowes may have universal crushproof hoses that will fit the CH515.

I recommend purchasing directly from Nutone if possible. The hoses are not too expensive, usually $30-$60 depending on the length. This guarantees compatibility and the right fit for your model.

How Do I Know if I Need a New Hose?

Here are some signs that it’s time to replace your Nutone CH515 vacuum hose:

  • Major cracks, holes, or damage – Obvious tears or perforations will degrade suction power.
  • Hose has collapsed or flattened – If the round shape has become oval, airflow is restricted.
  • Reduced suction strength – If your vacuum can’t pick up debris as easily, the hose may be blocked.
  • Loud whistling sound – This indicates a significant air leak in the hose.
  • Clogs frequently – Damaged inner liner causes more debris buildup and clogs.
  • Hose is over 5 years old – General wear and tear means it’s time for a new hose.

How Do I Replace the Old Vacuum Hose?

Replacing the vacuum hose on a Nutone CH515 involves just a few simple steps:

  1. Unplug the central vacuum – Make sure the system has no power to avoid electric shocks.
  2. Remove the old hose – Detach it from the wall inlet and vacuum power unit. You may need to press down on the inlet tabs.
  3. Attach the new hose – Push it firmly onto the inlet nozzle and power unit connector until it clicks into place.
  4. Test suction – Plug the central vacuum back in and turn it on. Make sure the new hose has strong suction.
  5. Check for leaks – Run your hand along the hose while the vacuum is on to feel for any air leaks.
  6. Clean the hose – Use the central vacuum to suck up a mixture of water and mild detergent to remove any debris inside the hose.

Take care not to damage the new hose during installation. Make sure all connections are secure and airtight. It’s a quick and easy DIY fix to get your Nutone central vacuum working like new again.

How Can I Prevent Hose Damage in the Future?

To maximize the life of your new Nutone CH515 vacuum hose, follow these tips:

  • Be gentle when handling the hose – Avoid excessive bending or twisting.
  • Inspect regularly for leaks or cracks – Replace at first signs of wear.
  • Keep away from hot surfaces – Heat can damage the vinyl.
  • Prevent punctures – Keep hose away from sharp objects and don’t run over it.
  • Don’t pull too hard – Tugging on the hose can detach it from the inlet or vacuum.
  • Check for clogs – Clear any debris buildup to maintain smooth airflow.
  • Hang up properly – Use wall hooks so the hose doesn’t get stepped on or crushed.

Taking proper care of your central vacuum hose will help it last 5-10 years or more before needing a replacement. Be mindful of how you use the hose and address any issues promptly to get the most out of your Nutone CH515 vacuum.
