Hi, Great to meet you! I have a 2006 Artesian Dove Canyon hot tub. Its been a pretty solid tub thus far. I think i went through 3 circulator pumps so far and a couple small parts. My tub has 4 dedicated pumps. I bought a Chlormaker sal****er system and also bought some Spa Guard system flush for cleaning the lines. I followed the directions and tried to drain the tub. The tub stopped draining with about 4" of water left. This has never happened to me before. I couldn't get it to drain so i started using my wet/dry vac to try and blow into the lines, and also sucking water out of them. That didnt work. So i ran a snake up the drain line and it did eventually drain.
I refilled and ran and was having pressure problems with one of the pumps that supplies 2 seats. After running it seemed to get about half pressure back. So ive been running my tub for about a month now. I turned that pump on yesterday and it didnt do anything but hum. I immediately turned it off. I turned it on again and it was pushing the jets about half strength. I also want to point out there are 2 air/pressure regulators for each pump. When i turned the air mix down i could hear a weird air sound ive never heard before.
So now i dont know what to do next. Could the problem be partial clog of the plumbing or my air pressure control is going bad? Should i try bleeding that pump?
