Valve Tech / CSV1W new question

« on: August 09, 2016, 06:10:33 PM »

I have decided to replace/disable the discontinued CSV1W with one of the newer replacements.  It would save me alot of time and effort(because of the way my system is installed) if I could add the new replacement at a different location further ahead of CSV1W on the incoming line, IF it is possible to remove the guts of the CSV1W and leave it in place.  By removing the guts of the valve will it then just act as a straight thru item in the line without effecting flow?  Wanted to know before I tear into it and put a new one in place?  Thanks for your time.

Valve Tech / CSV1W questions

Noted TomR message on complete CSV1W failure and your response on what has happened.  I have had the valve installed for 2years almost exactly.  Run time has been much less because I shut my system down in the winter and drain all.  Use only from May thru early October for lawn, shrubs, garden, etc.  I have long drip runs that are pretty minimal but think they exceed the 1GPM minimum for the CSV to work.  Lately I have noticed the CSV will not maintain the 50PSI default pressure and pump/tank cycle back and forth between 40/50 on all my drip runs. 
I have the 40/60 switch.  The CSV will maintain 50PSI when I run large gpm draws like lawn sprinklers lines.  When I quit watering the pressure only goes back to 50PSI which seems strange?  Should it not run up to the 60 switch max?  I have been pulling what little hair I have(76 years old)out and would appreciate your thoughts.  I am hoping I will not have to replace the CSV.  Could the air pressure in the tank bladder come into play at all?  That is my next check for tomorrow.  Thanks.
