As long as the Sonoff can handle the current loads that it would be subjected to handling the load current in the heating circuit then fine but if it turns out that the Sonoff cannot reliably handle those loads then the way I've suggested is pretty much how he'll have to do it.

@Jrock817 Here are some things to think about when considering what kind of tub you want to buy. First of all, how much do you think you're going to use the jets and do you need a kajillion of them? I think a lot of people who are new to hot tubs tend to think they'll use their jets a lot and...

@wayner I am coming into this conversation late and even though I did skim over what was said in many of the previous posts, I admit that I did not read everything so I'm not sure what I'm about to day has any relevance or is redundant or whatever but FWIW, this is what I have to offer. I had a...

Thanks, @RDspaguy, I kinda figured that would be the case but I just had to throw it out there in case there was some clever trick out there that I just couldn't think of. Dang, I wish that tub had isolation valves either side of the jet pumps! It's -13C so I really can't drain it now... :(

Watkins makes their shells out of acrylic and maybe ABS too. My old Grandee is an acrylic over ABS shell, not sure what the newer ones are made of. If yours is Acrylic or Acrylic over ABS then Plast-aid will fix any crack you might have in the shell if you can get to it. Just V groove out the...

I filled my nearly 30 year old 1995 Hot Springs Grandee late this year. Got it filled just before the freezing weather hit. I've had it running for maybe a week now and I've noticed the wet ends of both jet pumps are leaking out the back (I suspect bearing seals have worn out). On one of the...

The Plast-aid product you used is only useful for bonding Acrylic, ABS or PVC. It doesn't work on any other plastics or materials. The liquid solution softens/ partially dissolves the acrylic and the powder that you push into the crack also gets softened/partially dissolved by the liquid. Then...

I'm looking at ordering a new cover for my hot tub and I notice that some of the vendors up here offer an alternative to the standard marine grade vinyl material that I'm used to using. One vendor calls it Weatherguard but the others I've looked at call it Atlantis and one vendor I've looked at...

@Groot, I have a 28 year old Hot Springs Grandee spa which predates IQ2000 but I have modified it to use an IQ2000 system. It has the new 6 KW heater in it instead of the original 5.5 KW heater which died a long time ago. Those 30A heater relays the IQ2000 systems use were barely sufficient to...

I see I'm too late to offer a suggestion but I would've recommended using Plast-aid instead. It would've given you a stronger bond than JB Weld could. JB Weld just gives you a mechanical bond but on plastics like ABS, PVC and Acrylic, Plast-aid actually gives you a chemical bond which is much...

I disagree with a lot of what you are saying about 24/7 circ pumps. The one on my Hot Spring runs 24/7/365 whether the heater is on or not. It is NOT less efficient from a system that uses a jet pump part time for circulating. It is, in fact, much more efficient. Trying to make a large electric...

@Daf-Tekno , I too am from Calgary and would like to chime in on the perimeter vs injected foam insulation question. I have a 27 year old Hot Springs Grandee tub that I bought used with a number of problems but now have running flawlessly. During the first couple of winters I had with that tub...

Wherever you decided to order from, id you haven't already seen it, I recommend you check this old thread of mine before you order... All Spa Owners Should read this: Valuable Lesson Learned: ALWAYS Pull hot tub cover cores out and check them when you receive a new cover

I have a 1,893 L (500 US Gal) tub. Over time, I have gotten to know how much chlorine my tub needs with regular usage so I just keep a set of plastic measuring cups (1/2 cup, 1/3 cup etc. size) handy beside the tub so when I get out of the tub I pour out roughly what I need into one of those...

Personally, I don't like many of the newer hot tubs that are out there because they're too molded with too many sharp ridges and contours and I don't like how they force you to have to sit in a specific place and in a certain way. You can't sit an inch over in any direction from where they want...
