  3. My Kitchen Sink has a garbage disposal – can I use PermaFLOW?

    Yes, the PermaFLOW™ drain can be used in conjunction with the garbage disposal. It basically replaces the U- piece in the P-Trap below the sink.

  4. How do I know which size of plumbing I have 1-1/2” or 1-1/4”?

    You can measure the outside diameter of the pipe coming down from the sink or the pipe going from the p-trap to the wall. In case of many plastic pipes – this is also etched on the outside. Usually kitchens are 1-1/2” and bathrooms are 1-1/4” plumbing.

    PermaFLOW™ drain is universal design and fits both kitchen and bath sinks. It comes equipped with appropriate gaskets to adapt to 1-1/2” or 1-1/4” piping. Please visit the page ‘Installation & Operation’ on our website for detailed installation instructions.

  6. Can I use drain cleaners in my PermaFLOW™ drain?

    We do not recommend that you use drain cleaners with the PermaFLOW™ drain. We have tested the  PermaFLOW™ drain with many common drain cleaners with no harmful effects, however, drain cleaners with Sulfuric Acid can stain the PermaFLOW™ drain. If you perform regular maintenance, there should be no need for chemicals.

  7. How often do I need to turn the paddle on my PermaFLOW™ drain?

    We recommend that you turn your paddle once per week but this will depend on how much you use that sink. If debris starts to build up in the bottom, turn on the water and rotate the paddle a few times.

  8. What do I do if my PermaFLOW™ drain gets dirty?

    A very effective cleaner is a common denture (false teeth) cleaner. Simply put two denture cleaning tablets down your sink or lavatory drain and leave overnight. The denture cleaner cleans most stains.

  9. How does PermaFLOW™ handle hair and hairballs?

    PermaFLOW’s unique construction generates significant turbulence to minimize the possibility of hair settling in the Trap area, unlike the accumulation of hairballs in traditional traps. Hair strands are released into the waste pipe and on to the main drain pipe. Regular release eliminates accumulation and the corresponding problems though out the plumbing system.

    Additionally, in case of any build-up at the bottom of PermaFLOW, turn the wiper clockwise to push debris into the direct path of incoming turbulent water to break up debris and assist release downstream. This further reduces the possibility of large accumulations plugging pipes downstream.

    Since PermaFLOW is clear, generates significant turbulence and offers the easy to rotate wiper to swipe and clean, basic routine maintenance allows the drain to flow freely.

  10. Will my PermaFLOW Drain Leak?

    PermaFLOW drain has been designed and tested extensively to prevent leaking. PermaFLOW drain comes with a 10 year limited warranty that includes free replacement.

  11. 5. What is the life of the Wiper inside the PermaFLOW Drain? Does it need to be replaced.

    The PermaFLOW wiper has been tested under operating conditions for over 100,000 revolutions. If you turn it a couple of times a day, it is over 100 years. PermaFLOW drain comes with a 10 year limited warranty that includes free replacement.

  12. Can I recycle the PermaFLOW™ drain?

    Yes. The PermaFLOW™ drain is made from ABS plastic and is fully recyclable.

  13. How often do I need to replace my PermaFLOW™ drain?

    The PermaFLOW™ drain should last for a lifetime. However, over time the PermaFLOW™ drain may discolor because of different materials that you put into the drain. You may wish to replace it..

  14. You talk about Drain Management. What is it?

    Drain Management is essentially performing regular maintenance before a problem occurs. Regular cleaning of the PermaFLOW™ drain by using the cleaning paddle will prevent blockages in the PermaFLOW™ drain and help prevent blockages downstream.

  15. My home was built to “Sustainable/Green” standards. Is the PermaFLOW™ drain ok to use?
