Pumps, Wells, Tanks, Controls / Re: Considering a CSV - question

« on: October 13, 2013, 09:17:45 AM »

That makes more sense.  I had just glanced at it and it was probably sch 120 but when recalling it I was thinking psi.  I'll call them on mon to verify.  Same company that drilled it so they should have records.

One more thing that's interesting since the new pump was put in; and yes I believe it's the 12 gpm series, is now after say flushing the toilet it sounds like someone's doing a drum solo for about 15 seconds in the basement on the pipes.  That never happened before.  Ghost or water hammer?  Also the pressure tank is circa 1971 from montgomery wards.  I was going to check the pressure and when I unscrewed to valve cap water was dripping out of it.

So if I get a CSV I can get a smaller tank right?  Is there any harm getting a  bigger tank?  I did the math and normal size is about 80 gallons.  I would have peace of mind knowing I have some reserve in the tank if the power went out.

Thanks for your help on this one.

Pumps, Wells, Tanks, Controls / Considering a CSV - question

« on: October 11, 2013, 07:17:58 PM »

I just had a new pump installed.  The old 1 1/2 HP Red Jacket finally burned out after 18 years.  Replaced it with a 1 1/2 HP Stainless Steel Franklin Electric.

Well is 400' deep, pump sits at 360ish and static water is 250ish.

I watched them pull the old one out and I noticed the 1" PVC that is in there is rated I believe for 125 psi.

If that's the case and I put in a CSV, wouldn't the back pressure exceed that rating when I'm running say a sink or flushing the toilet?  The last thing I want is a burst line 300' down.  I'm already out $2,000 for the new pump and labor.

Is my concern valid when using a CSV?

Thanks for any info.
