I inquired and the local pool & spa business in town said I needn't worry about that diverter, to simply leave it in place, and to drain from the pump end, and there should be no problem. I'll just have to keep my fingers crossed at this point! I will simply vacuum and blow air everywhere I...

Here are a few pix - the polyurethane insulation makes it a bit hard to see where the lines are going. But, that's what it looks like underneath. The diverter I'm having trouble with is the one on the left. Thanks in advance!

Hello fellow TFPers! It's great to be back to a site I haven't visited in ages. I am winterizig a Jacuzzi J480 - winters are way to cold up here near Montreal, Canada. I emptied the spa, and was able to remove all but ONE diverter. All the lines have been blown dry, except for this one...

A contractor doing work in our yard recently accidentally damaged the power chord going to the spa. We changed the power chord and subsequently I replaced a fuse, but the circulation pump didn't work. I jumped it, meaning I bypassed the electro-mechanical relay, and the pump does work now...

Problem solved! A very large fuse (barely visible, yellow tags, bottom left in previous post) had gone bad. I replaced it, and voilà! spa is now running ... Nearly :confused: Every thing works, the display panel, lights, jet pumps, ... only the circulation pump isn't working. I measured...

Thank-you Jim for your quick response. It's raining cats & dogs today in Montreal - I'll only be able to check voltages between TP401 & TP404 tomorrow. I also need to replace a fuse that was damaged when trying to see if it was still intact (red circle in pic below). Ron Montreal

Folks, I fear the worst. To make a long story short, in the course of routine yard work, the power cable to the spa (240V, 3 lead) got damaged. The GFCI tripped, and the control panel was blank. I switched power to that circuit off from the home circuit breaker panel. Prior to replacing the...

Oh, good news, it's neither the board, nor the pump. It has to do with a "summer logic" consideration. My water is at 95°F and set temperatures is at 90°F (we're not using the spa for a few days). Voilà, circulation pump won't trigger under those conditions. It really helps to read the book...

Thank you Jim. I had forgotten to mention, indeed I am running in standard mode. Let's see what the voltage at the pump reads when it turns off! Thanks for the insight! Ron

Hello group, The circulation pump had been running fine, according to scheduled parameters (starting at midnight, running for 12 hours, per mfg suggestions). A couple of days ago, I noticed it was not running in the morning hours, at it is supposed to, till noon, that is. When I manually...

Thanks guys, I'll adjust TA first and go from there! Ron

This post relates to a friend's pool - not our hot tub! Volume of pool: 60,000 liters; water is sparkling clear. Numbers this morning using Taylor test kit: FC: 8.5 ppm pH: << 7 (below bottom end of color scale pH (according to pool store, notoriously unreliable) 6.8 Base demand: 10 drops...

Hello Will, I struggled with TA & pH the whole first season we had our spa. Long story short, through info gleaned on this site, I finally found that lowering TA (from usual recommended levels) helps in keeping pH in check and prevent it from rising so quickly. I lower my TA all the way down...

OMG, now I'm embarrassed! Time to have my Alzheimer's meds adjusted. I sincerely apologize for my confusion! Thanks a million for guiding me to my original post! Ron

Hello forum managers! Late last November (2017) I put up a post in the Salt Water Chlorine Generators (SWG) section. I was interested in designing a simple SWCG board, and control it with an Arduino microprocessor. I received one or two very interesting responses. For some reason this post has...

Thank you for your replies. I have these pictures of the filter - a Jacuzzi Laser 192. For the pump, I am not at the pool now, I'll have specs for it tomorrow. A friendly neighbor who helped early on in the season told me she occasionally changed the multiport valve position without first...

Hello, Our 24' pool has a sand filter. Debris (dead algae, DE) flow back into the pool from the filter. Never having seen this before, I wonder whether to consider this normal or if something is wrong. A bit of history: the pool came with a house we bought; we have no history of how the...

Hello group, I've found our spa relatively easy to manage for about one year now; the pH typically slowly drifts upward from 7.3 to 7.8 over a period of 10 days before needing adjustment. So now, the water in the tub is 60 days old, and twice this week, the pH has jumped from 7.3 to 8.0 in...

We're looking forward to taking our spa out of hibernation within the next couple of weeks or so. We did a line clean & purge (with Ahh-Some) just before winterizing. Is it advisable to redo a purge with Ahh-Some again upon restarting the spa? Ron Montreal

I just found a schematic - don't know if this helps. I have a sneaky suspicion that no 120V service is available from this controller. Regards - - - Updated - - - Thank you for your replies. JoyfulNoise: you are right on all points. My SWG does have that jumper, allowing it to operate on...

Hello TFP members! Our Sundance Cameo hot tub came with an add-on SWG - which is awesome! The spa is serviced with 240V; a power cord carries current from the main controller panel to the SWG unit, which also runs at 240V. Once the snow finally melts, :kim: I am planning a minor change to the...

Thanks for your kind replies. I was considering increasing borates to 50 or 60 ppm. Now I'm happy to see going even up to 80 is worth considering. Also I won't be so fussy about lowering pH - i'll wait till the water hits 8, then adjust to no lower than 7.6. But all that will have to wait till...
