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
