I will have to call the PB on that. I was unaware of the need for a check valve.
Water care has been really easy. All that I’ve had to do is add a lil MA here and there. Spa jets bring pH up fairly quick. And yes the cover helps some
Thanks for the input. My wife decided not to add them, plus i think having the spa blower running from time to time will be more than enough aeration to mess with pH.
Trying to decide if i should add sheer descents in the coping? PB says they don't put out much sound if not elevated higher than the coping. Any truth to that to those of you who have them?
