Frequently Asked Questions
What is a compression curb stop valve?
A compression curb stop is a valve installed in the water service line, typically at the property line, that allows localized shut-off of water flow during maintenance or emergency situations. It uses compression connections to seal securely around the pipe.
Can this valve be used with potable water?
Yes. The valve is made from lead-free brass suitable for potable water service lines and meets recognized industry safety standards.
Which pipe sizes are IPS valves used with?
IPS (Iron Pipe Size) valves and fittings are commonly used for larger service lines such as 1-1/4″, 1-1/2″, and 2″ diameters.
Do you need insert stiffeners for plastic pipe?
Yes. Insert stiffeners are required when connecting compression curb stops to flexible plastic piping such as HDPE to ensure a proper seal and prevent pipe collapse.
Is special equipment required for installation?
No special equipment is typically required. Standard tools such as wrenches are used to tighten the compression nuts. Proper installation requires clean, square pipe cuts and correct gasket seating.
Where is this valve typically installed?
It is typically installed underground at the property line, near where the public water service connects to the private service line.
What pressure can this service valve handle?
Curb stop valves in this class are commonly rated for approximately 300 PSI, suitable for most residential and commercial water service applications.
Can this valve be used above ground?
While primarily designed for underground installations, it may be used above ground if installed according to local code requirements and protected from environmental damage.
