I have a 6' x 8' in-ground gunite spa with bluestone around. My spa cover is about 9 years old and waterlogged, ripped, rusting ,etc. and weighs about 150 lbs! It has 2 hinge points (3 sections) 2 sections are permanently connected and the other section has velcro. I need to replace it but can't...

Ha! OK- Have some results: First ran the filter pump all night but turned the SWG OFF Tues 9:50 pm FC= 5 Wed 6:35 am FC= 4.6 So overnight I lost .4 Next I ran the filter pump all night with the SWG ON @ 100% power (skipped a day because of low salt) Thurs 10:20 pm FC= 3.8 Fri 7:30 am FC= 4.2...

OK I’m going to do the OCLT

Never thought about it but maybe the algae is overwhelming the salt generator- I will test it. Only problem is a few hours ago the low salt light started blinking- no surprise with all the rain. So, I had to throw in a bag of salt. Does high ph indicate there might be algae? It keeps climbing...

Dirk- agree, I'm past the expected life Jim R.- I ran the test. Turned the power to 0, then set it at 40%. The cell light was on 1:45, off 3:14, on 1:45, off 3:14, etc. Wow! I never knew it did that! Still, I've had the thing on for weeks at 100% and my chlorine has not gotten above 2 unless I...

I've had this Chlorinator for about 10 years and it has worked well, but this season I noticed it has been producing no chlorine. I cleaned it with muriatic acid, I ran the diagnostic that showed it was 60% used up. All the lights are green- good salt level, good flow, good cell. I understand...

ahhsome- thanks for the info. I did leave a message with Be-lite- waiting to hear back. They do have a different approach with the aluminum frame and all- looks like a quality product.

Hi have a 6' x 8' in-ground gunite spa that is flush with the pool and spills into it. My original cover (7' x 9') had 2 folds with hard foam in the middle, vinyl cover. It's about 8 years old and has gotten so heavy I can barely manage it- want something new. I took out the foam and see they...

JamesW looks like the bypass valve is OK. I will take the steps you recommended; cleaning the filter, descaling, etc. Hopefully that will bring my stack temp down some. Appreciate all your help and good tips and information! Thanks!

JamesW: OK I'm back with photos and updates... I put in the new regulator and the heater ran without stopping. The pump speed was level 3, 2495 RPM and the stack temp maxed at 420F- but it didn't go above that and didn't stop. I consider that "working" but I know that stack temp is too high so I...

Oh sorry- missed a few replies. Will follow up tomorrow.

I will give that a try and report back. Thank you again for all the help!

he filter may be dirty. the pump speed is level 3- 2495 RPM with 12 psi at the filter. at this setting BTW the stack temp I was getting was 436F I could bump up the speed to level 4 - 3270 RPM with 20 psi at the filter. I could see how the stack temp is then.

Wait- when you said entire system did you mean filter, heater, etc.??

I think I would have to disassemble more and the sun has set. Wish I had some kind of snake scope camera. I will have to take more apart tomorrow. Right now I've had the heater going for about 30 mins without the regulator and it stays on and heats the water properly- I got my spa from 70 to 90...

Thanks for the pic- I don't think I have an external bypass One more pic showing the area

OK removed the regulator and got the stack temp- it maxed out at 441 F and did not go higher and the heater did not shut off. I looked inside the hole where the regulator was and didn't see a spring This is all I saw

Do you mean remove he regulator spring etc -just leave in the black cap? And by stack temp you mean the same reading I got before by holding down SPA button?

JamesW thanks for the quick reply! It's funny because right after I posted decided to do his test, although I had read you hold down spa on and pool on at the same time. I wasn't sure what to expect but you just need to keep holding down- then you suddenly get a temp readout and it climbs and...

Hi all! I know I'm not the first one to have a broken down Mastertemp 400 with an SFS error LED on, but the earlier post didn't solve my particular problem. My propane heater has been working very well for the past few years. Installed in 2013, my first few years had mouse problems but I finally...

JamesW: I didn't think of the iron thing! Well- it's done. I left a hose with a low flow in there overnight and got the Ch below 4, Alk= 170, ph=8. I added 1 1/2 oz muriatic to lower alk and ph. The pool is big and partially empty so it had room for spillover. I would like try using the SWG on a...

JamesW thank you for your help. I'm just going to wait it out, keep running in the well water, keep it open and maybe by the end of the week it will be back in line. No point in adjusting anything until that chlorine is down. I should have thought of that dilution trick it's a good one.

It was running a few hours everyday but the water is cold- like 55F so I didn't think it was really generating much. Also, I forgot about it. I think I could use it if I put it very low and only put it on for a few hours before use but the best idea is probably no to use it at all- bad idea. I...

I like your idea of diluting the spa sample with distilled water. I will try that. I have a hose with fresh water going into the spa and just letting it spill over into the pool. I figured eventually it will dilute the spa water. I have some time.

Hi I have a 900 gallon in-ground gunite spa attached to my pool. The pool is closed for the winter but the spa is open and I have used it several times this winter. This is a saltwater pool/spa with a pentair salt cell generator that works during the summer. The salt level in the spa has been...
