    What is recommended treatment for Iron with Iron Bacteria in well water these days?

    You can't get by cheaply, trust me. I spent a ton of time researching IRB (Iron Reducing Bacteria). You have to kill it in order to then properly filter it (remnants) and the iron. I have a shallow casing well: about 38'. Can't recall what the hardness of my water is but I know it's not very...

    Removing PEX expansion pipe from plastic manifold

    Unfortunately I don't have room for valves :(

    Removing PEX expansion pipe from plastic manifold

    I need to do a full house re-plumb in stages (this is only part of major renovation work). I am using expansion PEX with several plastic manifolds (all from the same manufacturer). I was thinking of just blocking off some of the ports that I won't be using until I can later run lines end to end...

    PEX pipe support for 90 degree directional changes under floor joists

    OK... Per Uponor's installation doc it says that the minimum distance w/o bend support for 1/2" pipe is 10" along/to the connector and 6" along/coming from the run of the line: 5" and 5" WITH bend support. For 3/4" it is listed as 16" and 12": 8" and 8" WITH bend support. I may need to include...

    PEX pipe support for 90 degree directional changes under floor joists

    Surprisingly I can't find much information here on such a subject. I am [re]plumbing using [1/2" and 3/4"] PEX under floor joists and will need to make 90 degree course changes occurring between two adjacent floor joists: piping running parallel along one joist then needing to turn to run...

    PEX retro - most direct path or "clean" routing?

    But... there's nothing clean-looking on the underside of this place! And all the ugliness is "hidden" under the belly-wrap. I was going to build a new (real) house but that plan fell through and I'm stuck dealing with what I have. To put things in proper perspective, the sinks in the bathrooms...

    PEX retro - most direct path or "clean" routing?

    Yes, hot water lines being the most critical/affected. Though I am not a professional I nonetheless like to do things that look professional. Just kind of struggling with the notion of running stuff diagonally across[under] joists and such.

    PEX retro - most direct path or "clean" routing?

    Replacing existing cvpvc in a manufactured home. The cvpvc is run _under_ the bottom of the floor joists via straight lines (parallel and perpendicular to the joists) with Tee'd lines feeding the various fixtures. I will be doing a trunk and branch topology using manifolds. Is there any reason...

    Uponor colored PEX degradation -- two leaks so far

    FWIW - I contacted supplyhouse.com, where I purchased the pipe from, and they are aware of the current litigation and said that I can return the pipe for a refund.

    Uponor colored PEX degradation -- two leaks so far

    I purchased Uponor pipe and fittings back in 2019 for a repipe project for my home but put that project on a back-burner until now.. My pipe is colored. After running across discussion like here I'm now considering tossing it in favor of non-colored. More poking around I see that Ferguson, a...

    Replacement for Fleck 7000 SXT?

    Is there a Fleck model that is electro-mechanical that allows for setting duration on the backwash and rapid rinse cycles AND would be a replacement for my 7000? The 3200 timer has this capability but I have no clue about this valve; is this commercial?

    Replacement for Fleck 7000 SXT?

    Hello to all the folks that are still hanging around here! Been a while since I've been here: all has been working great water-wise. Looking for recommendations for a replacement for my Fleck 7000 SXT. I only need simple backwash (that's all I'm using the Fleck for): BW tank is 10" x 54". My...

    Treating Iron Bacteria and low pH and moderate radon

    7 gpm flow is quite an ask*. I'd suggest revisiting this requirement. A burst rate of 7gpm, maybe, but for any length of time you're going to struggle to obtain proper results. * Obviously, it can be done, but, as they say, just about anything can be done/achieved given enough money. IRB has...

    H2S Slippage; SRB's in Centaur Carbon Bed

    Running too high of a concentration of H2O2 into the carbon tank is taxing the carbon- it'll degrade the carbon (that is my understanding): anything that works will expend itself doing that work. I've always heard that injection should happen AFTER the pressure tank. I have injection post...

    Filter order for drinking well water

    What is in your water? Really need to know that in order to identify a solution.. Need some numbers from a lab (or if you have water testing equipment).

    AIO vs just backflush - trying to sort the wheat from the chaff

    OP, you need to provide water reports. I'll support Reach4's endorsement of H2O2 for iron and sulfide removal. That's what I am using: Stenner pump injecting H2O3 into a contact tank (I have iron reducing bacteria which requires contact time) and a Fleck 7100SXT (older unit) backwash filter...

    Is it possible to manually/physically control valves on Fleck 7000sxt?

    Following up to conclude... My filter is a Filter only. The valve only has "S" for service, "B" for backwash and "R" for rinse. New circuit board was installed and programmed and I'm back in business.

    Is it possible to manually/physically control valves on Fleck 7000sxt?

    My unit isn't configured for softening, no brine. Interestingly, the manual that I have and the online manuals don't show the same gear drive mechanism that I have. Mine only has "S", "B" and "R". I cannot run too long of cycles because I am using a contact tank and I cannot overrun that: I...

    Is it possible to manually/physically control valves on Fleck 7000sxt?

    Yeah, that's kind of what I'm thinking. I suppose that I can try it, making sure that nothing is feeling like it's giving much resistance (not wanting to have more broken parts than I already have!). I have that manual. Looks like counterclockwise to first "B" (backwash) then to second "B"...

    Is it possible to manually/physically control valves on Fleck 7000sxt?

    Circuit board on my 7100sxt is dead and I'm wondering whether I can manually/physically operate the valves in order to limp along until I get a replacement board. This unit has been operating for 8 years without a single problem. This video seems to suggest that I might be able to do so (it's...
