New member with questions

I am new to this forum and am excited to connect with others who are in similar situations. I am 67 years old and was diagnosed with MAI/Bronchiectasis in 2013. At that time my ID and Pulmonary docs suggested a "watchful waiting" course of action as my sputum cultures were not consistently positive and my CT scans did not show advanced disease. However the disease did progress and I started therapy with 3 antibiotics 9/2018 (Azithromycin, Ethambutol and Clofazimine. ( I had a febrile reaction to Rifampin hence the Clofazimine as a 3rd drug replacement.)
I take all the usual precautions to prevent micro aspiration and I now have an an odd question: My dentist recommended I start using a Waterpik water flosser (for reasons completely unrelated to the MAI diagnosis) and I am wondering if any of you have heard of any concerns about micro-aspirating of water with use of a waterflosser?
Another question I have is: I tend to not produce sufficient sputum for a specimen until evening and by then my lab is closed. I'm wondering if it's possible to keep a collected sputum specimen overnight and take it in the next day? And if so should it be refrigerated? I have asked this question of my MD and he wasn't sure and just said that I should take it in the same day but he didn't have any specific information to support that.
Thanks in advance for any helpful responses!

@julez I am responding only to the question of keeping sputum sample in frig overnight. My Mayo pulmonologist says it's fine to do that and I've done it at least 10 times over the last couple of years and it's been fine.
