Mastertemp 400 cuts off

cuts off after about 55 seconds and heater light flashes. No error codes. Ignites again after about 30 seconds and the process just repeats. It will still heat my pool spa to 100 in 45 minutes even w cycling.

I’ve jumped both sensors on sides of manifold and same result. Checked all grounds and they’re good. I’ve had propane pressure checked and it’s good.

Can anyone tell me what this part is on top of manifold?

My gut is telling me it’s a water pressure issue.

Pool Cover Cable Broken


Conversion to salt and help with testing

This has been a lot to take in but my pool is a mess. I tried to get it right last years but I could not figure it out.

For a quick recap I have

A sand filter with a chlorinator
a Hayward pump
vinyl pool with 25000 gillions

I am fixing to do all of the testing shortly and will post the results shortly. I have read through the pool school stuff but I need somebody to help me with a walk through because I learn better by doing as appose to reading.

Oh here is the SWG I am thanking about getting any thoughts? CircuPool Universal40 Saltwater Chlorinator | Discount Salt Pool

Any thoughts on dreame Z1

I have a Dreame for the house, it does a very good job. No idea on the pool cleaner. Looking at the website for this device, it does not seem like it has any features that make me like it more than an Aiper S1 which is half the price.
You have to watch the different ads, they aren't really doing the best job showing what it has, its similar to the beatbox aquasense ultra I believe without some of the bells and whistles. It has the sensor to detect the main drain and in theory go around it, they have that in a video. In theory it scans the pool using sonar or something similar so it can map the pool and actually get every part.

Need help on how to use my new spa

Jerry,

To turn on pump #2 you will need to turn on the "jets" circuit. You really should not be doing this while the spa is heating.. I would use the jets after the spa gets up to the initial temp you want. You can adjust the speed of pump #2 to match how you want the jets to work.

Just to be sure.. When you turn on pump #1, pump #2 should NOT come on.. Just want to make sure the two pumps have two different RS-485 addresses..

Thanks,

Jim R.
Really appreciate! Below screenshot is what I have changed based on your suggestion. Thanks!

A few follow up questions.
1. So what are each pump controls? Does pump #1 controls pool & spa, and #2 controls spa only?
2. What's the use of the Pool circut for (circuit function is Pool, and it's set in pump #1)? Is this used to circulate/filter waters in pool and spa, so I should run daily 6-8 hours at high speed? (and have spa spillover only work for half an hour twice)
3. I have in-flooring automatic cleaning system, which one control it? (I see there is a circuit function called Floor Cleaner, but no circut is using it)
4. There is an "Air Blower" curcuit (circuit function = Generic), but no pump is using it, what's this for?
5. What is "On w/Freeze", some is Yes, some is No. I live in Vegas, the temp don't usually go to below 32 degree in the winter.
6. There is another circuit "Aux Extra" with the name "AuxEx", function Generic, not seeing is used anywhere...

New pool proposal

3.5' is a bit too shallow. I'd suggest 4' for the shallow end.

6' is an awkward depth since it's too deep to stand, but too shallow for diving, etc. I'd suggest 5' for the "deep" part of your pool.


My reasons for the shallow is because I am 5’0” and not getting any taller (and will probably get shorter as I age). I can’t comfortably sip a cocktail standing in 4’ pool. This will be my probably forever home. I want to build this pool for me and not for the occasional guest. I understand that for most adults, this is a bit shallow.

As for the 6’ depth….we don’t dive but my boys love jumping in the pool. We stayed at a vacation rental with 5’ depth and we were hitting our backsides. I wanted to go to 6.5’ but the builder suggested not due to the slope. We have a friend with 6.5 and it’s perfect for the kids jumping in.

Funny you should mention sports pool. That was my first design though. I had 4 builders come over and all of them seem to hate sports pools unless they are large 20x40 or more. They said the slopes eat up the pool and there is hardly any flat surface left in a small 15x30.

Basically, I wanted to be able to walk in the shallow while the kids jumped in the deep.

Thank you for your comment and I will research further.

Pentair Intellicenter maintenance and failing connection

After this morning’s Intellicenter maintenance, my Pentair Pool app will not maintain a remote network connection with my Intellicenter. It connects and then shows connection failure after about 30 sec. Same result on both my IPhone and IPad. It connects via local network fine. I tried shutting off my Intellicenter and turning it back on with no luck. Just tried at 1350 EST. Anybody else having this type of issue?

Thanks!

New pool proposal

E,

Nothing to do with your proposal, but I don't like your stairs..

If you ever plan to do 'laps' in the pool, you only have one end..

I suggest that you add smaller stairs next to your sun-deck so that you can do laps.

And you also might think about going with a sports pool, so that you can do things like volleyball. Deep in the middle and shallow at both ends.

Thanks,

Jim R.
We have gone back and forth about the stadium steps. We love them and we don’t plan on doing laps. It’s more of a hangout pool. We were more concerned with the shallow area it eats up. Thank you for your input!

New equipment plumbing with lots of tight 90 bends?

Interesting. The check value is listed as “chemical resistant” - is that still expected to eventually fail? What is the alternative?

It is a saltwater generator pool, the tablet feeder is just a backup.

Feedback about a check valve instead of 3-way for the heater bypass is interesting, thanks to all who pointed it out.
I have a SWG but my PB also installed a tablet feeder "for free" which I thought I would use during the winter.

I've never used the tablet feeder, and I wish I didn't have it, as it's an unnecessary component which could eventually leak/fail. I'd ask your builder to remove it.
