I just sold my Pinnacle featured in this video, so it was in-use for about 8 months and the Kohree was flawless. Never had any issues with the Kohree and it was much quieter than the Shurflo I replaced it with.
So, I have the same issue as you in a 2023. That pump sounds like a hammer going to town. lol. I feel it is the same issue as you... too much pressure being forced into such a small line. I wish you had noise levels from at the sink. How much quieter is it at the water point? Good info and glad to know we are not the only ones with this annoyance.
@ 22:34 you can just barely make it out in the coach, but huge improvement. I'd say the modifications done in my first video (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YSlJXLKExOo.html) take the noise from 10 (worst) to about a 5 with Shureflow pump, and then the Kohree pump swap goes from that same 5 to a 3 (1=completely unoticeable). I think ultimate solution would be to re-plumb in 1/2 pex after 24" flex line, but I'll probably wait to do that till I have to take apart underbelly. It's a great idea Jayco has there...I think they have a patent on it, but the execution leaves a lot to be desired. Hopefully they'll listen to owner feedback to make some improvements to it eventually.
