Found a check valve on my system when replacing pump/pressure tank etc. Ran new schedule 40 to it from pump & new 1.5 sch 40 adapter to screw into it. That was appx 2 monthes ago, today found adapter had cracked where threads end at junction of female / slip end of adapter. Suspect I possibly screwed it in too tight but unsure & that thru pressure fluctions & or expansion contraction of temp swings it cracked. Normally am very careful when screwing plastic into metal. Since I am going to replace thought I might as well replace check valve since it's well over 30 years old. Did some research & there are full port check valves made by US Valve co. but they run $250 - $ 300 dependant upon if you want stainless steel etc. I remember someone talking about a check valve that had a more laminer flow than the one I have and that it had some type of egg shaped seating device. The one I have on right now is the old conventional spring / disk seating type. Am trying to find the name of the one that has the egg or bullet shaped seating device.
