The extra holes just allow a little bit more flow, completely optional.

I'm going to go with what Jason said. It would have to be stress related. Perhaps overtightened at one point ? Nice way to fix it however.

I would have to say Yes. Personally I think it would make things a bit hard to maintain. The 3/8" line gives more flow then I would suspect anyone would need short of a very large pool, in which case they would probably not be using a Liquidator. Just my opinion of course.

Aquaman95, just wanted to let you know I received the pinch valve today and I'm in the process of trying to get it all working again. The coil is still good, so there is hope without a doubt. It doesn't appear to be frozen, but the travel distance is very very short. I'll let you know how...

Wow, I would love to try and get that working again. I sent you a PM with my info. I can't see myself spending $165 on a new one as I haven't spent half that on my entire project so far. Thank you!

It's on the outlet side of the LQ and is normally closed. It's pretty much a spring loaded solenoid that covers a hole. When engaged it opens the hole and allows flow. The bad part is that it would have chlorinated water flowing around the stainless parts of the solenoid. Pinch valve...

I will do some research on this, I want to be sure this project works correctly.

With the right tools and experience it's not all too hard. I've been doing this sort of thing as a hobby for about 25 years. Chances are I'll just drop it, easy enough to remove it from the code and will free up a bit of memory. Ya, I was kind of thinking the same thing. Do you have any...

Very good point. I might also be able to compensate for this in software. Perhaps a settable overshoot offset that causes a delay. If you were targeting 650mv the software might shut off at 630mv and not check again for say half an hour. Once the time is up it could test and inject for 15...

I'm actually using a look up table. It will allow a non linear ramp. Pretty much instead of calculating on the fly I would like to use the table to just read a pre-calculated value. That's not to say an equation for adjustment could not be applied against that looked up value. Thanks for...

Hey I like that idea. So is there any way to even get in the ballpark with the ORP to PPM relation ? Not that I really need PPM, I just thought it would be nice.

Well I've been working this spring on my Liquidator automation controller. I just need some help from someone with some experience in the field converting mv to parts per million (ppm). Here is my project as it stands now, I've started to layout the circuit board for the project and I...

I'm no expert in the subject either, I almost ordered the wrong parts when I was first preparing the project. The whole 1/4 inch thing is very confusing. I can say however that the parts list I gave works. I think a few others can confirm this.

I used an Epoxy Appliance white. It holds up really well, just takes a long time to dry. I left a masked off strip down the side so I could see the level.

1/4" NPT is what you want for 3/8 ID line. It's much larger then 1/4". It's very confusing I know. See this page. http://en.wikipedia.org/wiki/National_pipe_thread
