Sorry, I was not clear. TDS for the RO water is 85 and the TDS for the pretreatment water which is an input to the membranes is 280 (Coming out of the Carbon + Sediment filter). Yes I am seeing the spots right now.

Is this the one that you are talking about Ozmosis XLE-4040 Reverse Osmosis RO Membrane for Water Filtration System 4"x40" ?

This message contains a lot of useful information, and I've learned quite a bit. I realize that I need to invest in a water softener and replace the media in my carbon tank. I also plan to measure the chlorine levels. Currently, the RO water measures around 280 TDS, but I haven't measured my...

Thank you, reject water from the RO, right? Also, what chlorine levels should I look for that indicate it needs a service?

I did not see anything on housing, as suggested here I plan to gasket to a hardware shop and get a replacement. Thank you everyone.

Hello: I am currently using KR membranes https://www.kleen-ritecorp.com/p-44539-kleen-rite-reverse-osmosis-membrane-4-x-40-inches-2500-gpd.aspx two of them on my JC unit. I end up replacing them every year, and my TDS meter is currently reading 85 ppm (due for change). I have a few questions and...

Hello, I have a JC system, and the blue sediment prefilter O-ring has worn out. Does anyone know the correct size for this gasket? A part number or a link to a suitable replacement from KR or Home Depot would be very helpful. Thank you!

Here is a good Youtube video for testing 3 phase motor:

If you have the latest iPhone Pro Max, it may help. I have got better results on my iPhone in enhancing such images.

I have the JC system installed, which includes the weep functionality. While I don't have check valves on the HP line, both the tire cleaner and Soft Free, which are connected via tee to the HP manifold in the bay, do have check valves. I've ensured that all the Soft Free check valves are...

Yes, good idea. I am going to give this a try.

Cool, thanks! So, my weep solenoids are supposed to be normally closed, right? I checked the poly line, and no water came out, confirming they're closed. Then, I tweaked the weep temperature, and they all activated, flushing out water. The mixture tank level stayed the same, though in my...

Yes I am based in Houston. I'm still trying to understand how my weep function operates on my JC system, as it's not something we frequently engage with or maintain. Currently, I've closed the ball valve that links the weep to the pump, which is accompanied by a check valve. Additionally...

The presoak, along with the soap and clear coat, is injected into the cat pump. The tire cleaner and Softfree, however, are fed through a separate line, which is teed on top of the bay. We are experiencing this issue specifically with the presoak others look good.

Thanks! That's what my initial thought was. I did look over all the solenoids, and I ended up swapping out a few that seemed rusty or had sticky stems. Others looked ok. I also added a check valve, just to rule out this issue. I thought it would be airtight, with no drops. I ignored the drops...

So, I've got this weird thing happening with my presoak mix tank on my JC super saver setup. It's acting all wonky - the mix seems watered down, and the white tank isn't sitting straight (attached pic). I've tried a few fixes already: Swapped out the old Hydrominder for a new one. Popped in a...

Thank you everyone for your input. I know what I need to get now.

Does anyone know what is the difference between these check valves Brass and Stainless Steel? Why is the brass one so expensive?Which ones do you guys use? TIA

Hey, thanks! No hot water tank here. Just to clarify, you're thinking the check valve in one bay's weep mizer is acting up. It's causing water to go backward when customers use that product (CAT pump's running + solenoid's open). If that's the case, it should have happened with other functions...

Hello - I've got Jim Coleman super saver stand, and I'm dealing with a bit of a glitch. It has a rinse tank and each bay has a ball valve and check valve. Right below the ball valve it T's into soap, wax, and presoak. The snag is when the brass plunger/stem gets stuck, the rinse water backflows...
