Hi, Will this suck the detritus from a sump that’s at floor level to a faucet that’s 3.5 ft higher and 20 ft away in the same room?

If I purchase the 50 foot length does it have a 25 foot extension included that can be removed or is it one complete 50 foot length? I need it to go to two locations and don’t want the extra hose length when not needed.
Question by: Brian Smithey on Feb 3, 2023, 9:32 AM
Thanks for the question! It will come with 50 ft!

I am trying to connect this to my bathroom sink faucet which has an embedded aerator that will need to be removed to screw in the Python, so the faucet has female threads with a thread specs of M21.5 x 1.5-6G (per Moen). Will I need an adapter to connect this to my faucet?
Question by: Ray Valentino on Aug 28, 2022, 10:20 AM
Hey there,
Thank you for reaching out to us. This comes with a brass adapter to change your faucet female thread to male thread.

Please let me know if you need anything further and take care!

What size is the tubing? If BRS sells the replacement tubing by the foot, then will you please post a link in the answer so I can buy it from BRS?
Question by: Fred Mentzel on Sep 6, 2020, 1:15 PM
Hey there,
Thank you for reaching out to us! The tubing is 5/8". Unfortunately, we do not sell it by the foot.

Please let me know if you need anything further and take care!

If the distance from my sink to my tank is 25 feet and then 25 feet from the tank to the sink, do I need a 25 ft or a 50 ft. I assume I would need two hoses, right?
Question by: Steve on Nov 21, 2017, 7:37 AM
Hey there,

The no spill water change system will allow you to drain discard water directly into your sink. For refilling with premixed water, you could either disconnect the hose from the sink and attach to a fill pump, or you could have an extra hose specifically for this purpose. Really up to you.

Have a great day!
Answer by: Zack on Nov 24, 2017, 11:04 AM
Will this work if you have the faucet connected in an upstairs laundry room with the tank being on the lower level 15/20 feet height differential at a guess.
Question by: Marc Upton on Apr 16, 2016, 10:38 AM
Great question!
It will depend on the water pressure from the source faucet however in most cases this can draw water up to 5-10 ffet up. Much higher on standard homes water pressure and the system is not able to reach much higher than 10'. Feel free to let us know if you have any further questions!

Question by: Roger Fagler on Feb 9, 2016, 2:20 PM

Can saltwater go into a septic system or will it cause issues? I watched tons of videos before starting and one was a professional cleaner showing how to clean a tank and she said it was bad. I have tried to find another source to confirm or deny but no luck and I like the idea of this hose.
Question by: Crystal on Jan 23, 2016, 9:19 PM
Great question!
In short, placing larger amounts of saltwater in a septic system would cause issues. We unfortunately are not qualified to answer directly however it would have a negative impact on bacteria and other elements in the tank. Overall another drain alternative may need to be found. Feel free to let us know if you have any further questions!
