Valve Tech / Re: CSV1Z pressure adjustment

« on: November 13, 2012, 04:38:23 PM »

The split pipe just occurred. Heck, with the split pump ran constantly and barely got to 40. Heated up the well from 55F to around 70F. With the cooling sleeve that was recommended, don't think the pump is hurt. IOW, that was a different issue I had to fix ATM so my wife will stop asking when she can flush the toilet. Since I was taking the time and having to drain, etc wanted solve the other issue at the same time.

Anyway fixed the pipe and also installed the gauge I was using for my test jig - one of those fluid filled ones. It turns out that the original pressure gauge is a POS - even if new. I'd put a note in your instructions to discard those cheap gauges. Not all that much more.

Yes, it now works as advertised. Happy. Don't think I need to remove the spacer. Only check valve is the one in the pump.

Thanks for the time and explanation of the plastic spacer. I don't think I need to remove that. I now have 60 PSI using my old cutout switch which I upped to 70.

I measured the flow first for the regular outdoor faucet I was using using a timer and a measured container that is exactly 3 gallons. It is under 3 GPM. Then did the adjusting. It went to 50 with some room left. Adjusting further all the way to the plastic stop it stayed at 50 (+ a litte).

I'm working on what I think will be a broken plastic pump pipe, so I thought I'd figure this out at the same time.

That repair is what I'm going to do the minute I send this. I'll double check what I wrote. If it's exactly the same or if somehow I messed up, I'll give you a call later. Thanks.

I actually got a regular 60-80 switch to do 60-70 (could be 75 though - been a while, I haven't installed it because of the pressure setting issue). That's what I was trying to explain about how I built a little test system that let me play with the spring adjustments. The low side has -0- tension on the spring.

Thanks

Valve Tech / CSV1Z pressure adjustment

« on: November 12, 2012, 08:12:30 PM »

I installed a CSV1Z 7/2011 and it works great, with one thing I can't figure out.

I though I was supposed to be able to adjust the pressure way past 50, but somehow I can't do that.

My valve adjustment has a plastic spacer about 1/2" thick where the adjustment bolt passes through. I have it adjusted all the way 'tight' to the spacer so it can't go any further. It could if the spacer was removed. Yet, the pressure (when tested using the procedure in the instructions with a flow) will not go over 50psi when drawing. When I shut off the water draw, pump goes up to 60 cutoff and everything shuts off. Pump is a grundfos 16s10-10 and my well is 50ft at the pumping depth.

Is the spacer supposed to be there? I see no mention of the spacer nor see it in any pictures. Can I remove it and just turn the adjustment down more?

That's the only thing that has me baffled.

I did see that the pressure band can be much narrower from another post.  I want to make it 60-70 and thus raise the CSV pressure along with it to at least 65. Now my switch settings are the standard 40-60. I built an air test system using a 60-80 switch where I could adjust the manual cutoff switch without having to actually run the pump, drain, etc. 

thanks for any advice
