I'm working on a fitting leak on my J-365 tub. It looks like the leak is down below the waterfall. It's a foamed tub, so I'm digging foam out, but a picture of the hoses and fittings in that area prior to foaming would be really helpful. Any ideas where I might find such a pic?
Thanks!

Theses pics are what's there give or take the actual waterfall itself. The barbed fitting and that white fitting are whats attached to the 3/4" line. Better chance the waterfall is leaking vs the fittings. But I have seen both.

Thanks for the reply, Jim! I tracked the leak to a split white plastic 2" fitting connected to the big 2" flex PVC line way down under the waterfall section of the tub. Looks like frost damage, as the tub sat empty last winter, but wasn't professionally winterized. Previous owner said he blew out all the lines with compressed air, but...she be leakin' :-[

I just fixed a leak in my tub and used an epoxy repair putty from Home depot, it was inexpensive, bonded with the pvc and after it hardened ( I gave it an hour) didn't leak. My tub is 10 YO and the part looked like a bear to replace ... Someone here mentioned using something like that and it did work great.
If you do use it just make sure you mix it really well, put it on where it covers the hole plus overlaps the area by about an inch or so and give it time to harden before setting it up. It does say it can work underwater but since you are talking possibly some pressure pushing out, I would give it ample time to bond and dry.

Hi Vinny, thanks for the ideas. It's miserable out right now, but I did manage to clear out the leak area a bit, and took a picture of the part. It looks like a PVC assembly that perhaps the ice pushed apart? Water runs out of the vertical crack. The picture in question is taken at the bottom of the tub on the waterfall side (opposite to the equipment side).

Not sure, but I think that might be a check valve to one of the main pumps? What size line is that running into it?
-
That's a big 2" line running into it. It looks like there's a seam in that fitting, and it's been pushed apart, presumably by ice action. Tomorrow after work I'll work on trimming back the foam better in that area. Just above that fitting there are some very small hoses, so I'll need to work slowly to avoid causing collateral damage!
-
We don't see a lot of Freeze damage, but any I have seen doesn't push, it cracks fittings. Most likely a bad glue joint. I think it's a check valve and that right end runs to a suction fitting in the foot well. Guessing you follow the other end and it will run to pump 1. Doubt any kind of putty type product will work, your going to need to cut that out and replace it with a new check valve. Honestly it's going to be a pain getting in there and replacing.
-
I thought 8t looked like a seam as well but was looking on a phone screen.
As far as the epoxy putty, it wouldn't hurt to try. The stuff at HD is about $3 for 2 ounces ... Buy 2 and you should have more than enough. It is rated for some pressure (I think like 120PSI, but don't quote me) and if it works great if not you wasted $6 and an hour or so of your time.
My repair was on an air valve joint, I used 3/4 of the putty to put all around the joint and spread it out a little, waited for it to dry, filled the tub and it held. Would I have gotten the same results if there was pressure IDK!
-
Put the epoxy on there to seal the crack, then wrap it with silicone "rescue tape" to keep pressure from blowing the epoxy off.
-
Here's the stuff I got:
http://www.homedepot.com/p/RectorSeal-EP-200-2-oz-Epoxy-Putty-Stick-97601/100124697
The MFG claims it holds up to 1200 PSI and 500 degrees.
I think if you can get a good bead around that pipe with a nice overlap it just may work. Maybe push some of the putty into the crack (small amount) making sure you have enough over it as well (don't think using it in a thin layer).
I'm sure glad Jaynen gave me that suggestion!
-
Thanks for the suggestions, guys. With a bit of work I managed to pull out that section. As it was split all the way around, I was worried about patching it. The fractured part is a check-valve. I've purchased a replacement, with connectors, and aim to get this fit in place tomorrow.
Assuming this is the last leak, any thoughts on what should be done with the wet foam underneath? The bottom few inches are pretty soaked.
-
What I did with mine was take out as much foam as I could and bought that rigid foam board insulation. I tried that great stuff in the can but it didn't work too well so that's when I went with the rigid foam. I only used an inch so that area only hàs an r4 value but its kind of a smallish area . there was a ton more insulation that was wet and I couldn't get to so I'm hoping it eventually dries out. I will say that I don't know if I should have left that wet foam in or not so hopefully someone else can chime in.
BTW, great job taking that out! We're there unions? Or was it a hacksaw type of job?
-
Sawzall and manual cutting with hacksaw blade got the broken piece out. Getting the big nut off the water inlet going through the side of the tub was the biggest challenge. There wasn't enough room to get a tool on it, and it wouldn't budge by hand. I ended up cutting notches in the edge of the nut, and prying it up with a pry bar against a wood block. Major PITA, but it's out now, and the replacement pieces installed.
Here's the butchered parts after removal. That check valve was split all the way around.

And here's the replacement parts. The local pool & spa guys didn't have the same style check, but they said this one would work. I had to replace the water inlet fitting also, but it's not shown here.

Job done. Hopefully the next trip to the spa shop is with a water sample, not another broken part...

Yeah!! It holds water! Now on to the next issues. There's a few small drips from a couple of the 3/8" PVC tees in the bypass circuit. The hose is pretty stiff, so I think I'll just replace, and use gear clamps rather than those spring-loaded jobbies that are pretty rusty at this point.
One other issue is the faulty flow switch. It seems to close when watching it visually, but I get FLO error on the panel. When manually shorting the leads, the heater starts properly, so I guess flow switch swap is the next step.
Oh, and to complete my show and tell, here's the other freeze-damaged hose I replaced. How's that for a nasty crack?

Sounds like you'll be basking in 100 degree water very soon!
-
Been there done that a bunch, good job renns. Couple contacts for parts and leads your in the business. That's how I got started. But being a plumber it seemed natural even though I wasn't plumbing for a few years (leadership).

Picked up a couple PVC tee's, and some 3/8" tubing, and replaced the last dripping bits. It was a bit of an adventure with a full tub. My son covered some open ends, I covered others while fitting the new parts. Power off, of course.
Good news on the flow switch front. I looked up the part number, and found the manufacturer's site (http://harwil.com/model-q-12/). The switch has a little finger that sticks up into the flow path, and moving fluid drags it over, causing it to actuate. The switch in my tub was mounted with the finger 90 degrees off the flow path. The little finger was quivering away in the moving fluid, but didn't move over to the actuated position. I rotated the switch body, to orient the finger properly, pulled the jumper out of the circuit, and the tub powered up and worked just fine. No more FLO error.

There's more issues to address - a couple jets need replacing, and the built-in stereo powers up but there's no audio. Those issues can wait. Need to finish a glass of wine, and eat some left-over candy - only a half-dozen kids this year. Usually we get 20-30.
Tman - The local pool and spa people were just great. They had lots of stock of parts, and were very encouraging, and free with advice. I'm sure they're looking forward to another customer for chemicals and supplies, and I'm quite happy to oblige. I'm no plumber, but have tackled a wide variety of home and auto repairs over the years, so the actual work wasn't bad. It just took time to familiarize myself with the equipment, as well as deal with the thick layer of foam hiding everything.
av8r - up from low 50's to 80 now. We'll bring a water sample in tomorrow or Monday and figure out what we can use from our big pile of spare chemicals that came with the tub.

Excellent!!

Great job on the repair!
I procrastinated on my leak and I think it led to my pump 1 making noise. I had repaired that pump, replacing a leaking seal, last year and I want to kick myself for letting that leak go especially now that I saw how easy a fix it was!
Jets should be easy, I have a few myself that need replacement and they are Waterway so in the Spring I will replace along with that pump repair.
Hopefully the no audio for you will be an easy fix. Enjoy the tub!!

We have it up to full operating temperature now. I put in the recommended shock dosage, plus the 150ml of 'Stain and Scale' that was recommended I stick in when first filling. The local shops are closed today, so no luck on water testing. Is there any harm in hopping in and enjoying the fruits of our labours for a few minutes tonight?

I did when mine came up to temp the first night. 40 minutes soaking. I'm still alive.
