AHA! Slapped in the face by another senior moment. I should have figured that out on my own.

A pretty kitty cat/water taster-tester. If TFP would allow, I'd post more pics.

If it's good enough for them, it's good enough for me?

IMHO - It's a shame that they haven't figured out how to improve this app significantly. Modern smartphones have cameras so good that they rival even some DSLRs. This app should at least be a close second to other methods of testing. The first thing missing is a calibration procedure that uses...

I just put in a new 406. Same thing. Maybe more. What bothers me most though is the swing/differential/hysteresis/or-whatever-it's-called. The hot tub will heat and shut off in 15 or 20 minutes to what I feel is comfy. But before it comes back on it starts to feel too cool. I don't know if...

I'd like to see what's inside. If you're game for a little inexpensive experimentation ($10-20) a cheap Chinese/Amazon/eBay remote could work if it's on the right frequency. I use a four-button to control my pump speed and a single button to control the heater on/off.

Thanks for all the comments, folks. It looks like the noise and shipping damage are being overstated. I'm looking at the Raypak now, too. As for rodents, $700 will buy a LOT of mothballs.

I want very much to pull the trigger on a new, more efficient heater, the MasterTemp because the footprint is small and should be close to being a drop-in replacement. However, there are some comments that give me pause: 1) They seem to be prone to being damaged in transit. 2) They've also...

That's what I was seeing yesterday. Though I don't always expect it to be so. That would be me. It's a DIY black irrigation tubing affair. It sits on top of what we call the Ramada (a 6x28 corrugated steel roof over the equipment pad and propane tank). Maybe 4 feet higher than the filter gauge...

I'm playing with pump speed and watching the incoming/outgoing water temperature differences. I've learned from reading here that more volume is generally better than less. But too much flow can also be bad. Looking at it from a different perspective, do I want a greater delta or smaller delta?

That's my conclusion, too. I can set a minimum speed. I just can't set it to zero. No biggie. I can live with it.

Sorry. I should have been more clear. The instructions for the wireless relay state - 7. Add one function of ALL OFF : press two remote buttons at the same time ( sent Combination codes ),all the relays are disconnect. (I believe the language is called Chinglish.) I do know that in the...

I have an intellicomm II and a really cheap 4-channel wireless relay kit. It works well and does what I wanted but for one minor nit. According to the "instructions" I should be able to press any two buttons on the remote and issue a "ALL OFF" command. It doesn't work, but it's not a show...

Thanks, all. It's nice to be here. YippeeSkippee: CYA pegged at 250+ PPM on the strips my BIL gave me after he got his drop test. He offered to bring his kit over, but since he's on the other side of town, My TF-100 kit is due today or tomorrow. :D

We just bought our fourth home. The first with a pool and a spa. The previous owner used tablets for 10 or 12 years and apparently never addressed the issue of CYA buildup. I wouldn't have believed the level could be so high if I hadn't seen it for myself. Thanks to TFP and the collective wisdom...

This makes it look very easy, but has anyone tried to rotate the display\keypad 180? Another thing that looks easy would be adding an extension cable as a DIY remote keypad. Anyone? Thanks Rwhite692 for posting those pics! Very inspiring to my inner hacker.
