Yes indeed. I suspect it is not long for this world.

I think you want the NXT2 timers.

Maintenance of Fleck valves... Ugh.

Never, never, ever run a procon pump dry. You'll destroy it in short order. Pressurized feed to the pump is ideal. Russ

Yep - some of the things that go into recommending a certain capacity RO (in gpd) include: *minimum winter water temperature *capacity factor (essentially how many hours of the available time do we want the RO to have to run to keep up with demand), and *size of the storage tank. The "Gallons...

I agree with Waterboy - "Recovery" and "Rejection" are two critical metrics when operating an RO system, and they are understood by very few car wash managers. A little jargon to help understand this: Feedwater: The water delivered to your RO system - after any pretreatment like a carbon tank...

I have a list somewhere around here

Be advised that as of the end of 2024, Fleck (historically, the most common brand of water treatment equipment in carwashes that I am aware of) discontinued production of about 2400 parts. The very long list includes some replacement parts for more than a dozen water treatment valves. Some of...

As of about 3 weeks ago, Fleck sent out a message to their distributors identifying a large number of parts they will no longer be making. I can get more info/specifics on this if people are interested. Russ

We've had good luck with Axeon membranes over the years. We stock their 4040's @ 225 psi, 150 psi, 100 psi, and 80 psi. We also have the full lineup of Filmtec membranes.

If you get up on a ladder and look at that DM2 inline TDS meter on your RO, here's what you'll see. This meter has cables running to two separate TDS probes. Typically, one is mounted on the RO feedwater (which should be after your carbon tank and softener), and the other is mounted on the...

Rather than add a DI tank to your set up, I'd concentrate on tweaking your RO system so that it produces permeate with a lower TDS. I don't like where this is mounted because you need to be keeping tabs on what the gauges tell you, and what the DM2 inline TDS meter (the small white box at the...

Maybe this will help. A twin tank alternating softener is installed so that the softener can produce softened water 24/7/365 without interruption. Components of the softener and carbon tank valve need periodic maintenance.

We have a customer on well water in South Dakota - he reports 2400 ppm TDS. :oops:

Making assumptions about a bunch of variables, here's some comparative info with ballpark $. The old Fleck 9500 is a 1.5" brass body, metered, twin valve. The cost of that valve and associated parts (not including tanks, media, etc) is about $3200. An assembly of Clack parts (two brass 1.5"...

I'm happy to quote whatever you need. Russ

There are much more cost-effective solutions for the same equipment they provide.

So you must be dosing an anti-scalant?
