Re: [RE-wrenches] Water system with Grundfos SQFlex

HI Brad, Is this off/on grid? And are the two wells near each other or they just join up at the tank and float switch? If you’ve got the power then I’d install just a standard AC centrifugal pump. Sure uses more power but lasts forever. And is maybe $500 vs $2500 And you’ve said minimal water

Re: [RE-wrenches] Water system with Grundfos SQFlex

OK, all of the fittings were just fine. After pulling the pump it was obvious that there was a total failure of the Grundfos SQFlex 3SQF-2 pump head, both the rotor and the check valve. Water just pours through it in reverse with no pressure. On the last test in place it would not produce more than

Re: [RE-wrenches] Water system with Grundfos SQFlex

Sorry Brad, It's been a long time since I did well work, and now, I can't find a supplier of the fittings.  The pics I sent earlier were just representative, but not exactly what I used in the past. What I had used were bronze compression fittings similar to liquid tite conduit male adapters.

Re: [RE-wrenches] Water system with Grundfos SQFlex

Those are the exact inserts that I've used. Here's the clamps: clamps I'm not too keen on buying from Amaz... so if you know of any other source for these clamps let everyone know. I have installed two clamps per ins

Re: [RE-wrenches] Water system with Grundfos SQFlex

Brad,For hand installation, especially with lower flow rates, my go-to solution, mentored to me by Windy Dankoff, was SDR9 high-pressure (140 psi max if I’m remembering correctly) flexible polyethylene pipe with bronze SDR9 compression couplers and connectors to MPT. They all used a stainless steel

And of course using a torch to soften the tubing just enough so that the barb fitting can insert and then grab into the plastic with the clamps. For 1” its not needed but helpful. For 1.25”- 2” its needed, or at least I’ve never been able to get a solid connection without heat. Jay > On May

Poly or pvc is very common here in Northern California, and I have seen threaded schedule 80 PVC which takes longer to drop or pull but is a pretty nice solution.Michael D NelsonMD Electric & Solar, Inc.707-684-0064 mobile707-884-1862 officewww.mdelectricsolar.comwww.facebook.com/mdelectricandsolar

Re: [RE-wrenches] Water system with Grundfos SQFlex

Ray, Do you have a US supplier for either of these fittings? The Jentro fitting looks great, the Blueseal16 does not look like it would have much of a pressure rating. I did not find a specification. What do you all use for drop pipes for well pumps? I have a 260ft deep well with galv, but the f

Re: [RE-wrenches] Water system with Grundfos SQFlex

Hi Brad; I've seen a lot of leaks with barb fittings on poly pipe. I just replace most of the poly plumbing at my place, because I just couldn't get it to stop leaking. Black poly pipe is the lowest cost per foot, but not quite bomb proof.   Barb fittings are really more suited for irrigation

Re: [RE-wrenches] Water system with Grundfos SQFlex

I had a similar pipe leak. I forgot how I located it, but I used a vaccumn gauge or pump and to determine how far down the well the the leak was and pulled the pump and pipe and found a crack. On Sat, May 25, 2024 at 8:41 PM Bradley Bassett via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrot

Re: [RE-wrenches] Water system with Grundfos SQFlex

Yes, lots of possibilities for leaks. I will be exploring them today. Thanks for the tips for finding the location. This setup uses 300psi 1" black poly pipe on a 25 ft drop, and then about 1200 ft run of the same pipe up 220ft elevation to the tanks up the hill with the house about 36ft below the

Re: [RE-wrenches] Water system with Grundfos SQFlex

Hi allYes the pump won’t go backwards but it’s possible there could be some leakage through the helical coil. But both check valves have to fail which is a low probability. I’ve seen pipe broken due to someone closing a valve and not having a pressure relief valve. Not knowing what kind of pipe/fit

Re: [RE-wrenches] Water system with Grundfos SQFlex

Brad, Windy might chime in at some point to back me up on this but I see no way for that pump to turn backwards. Reverse flow is likely a leak at the pump, the down well piping or at the pitless adapter if there is one. Roy Another old time solar and wind guy, hoping to be retired someda

Hey Brad, Sometimes shooting is best if you tell more on what you have done so far like using the SQF shooting guide, especially on a holiday weekend😉 Assume there is a CU200 controller and pump is in ground still, must be with 100ft head, sorry No high amps? It runs, How old? --Dave Dave An

Re: [RE-wrenches] Water system with Grundfos SQFlex

Hi Brad With 2 check valves leaking I’d look for a broken pipe or a corroded fitting. If there is anyway to isolate between the 2 check valves then you could measure the pressure drop on both sides which should point to the direction of the leak. Jay > On May 25, 2024, at 7:41 PM, Bradley B

[RE-wrenches] Water system with Grundfos SQFlex

I have a water system with a Grundfos SQFlex SQF3-2 pump. I'm getting water flow in reverse either through the pump or a leak up to the pump. My question is if the check valve on the top of the pump is not sealing, will the progressive cavity pump allow water to flow through the pump in reverse? I'
