Model 5000-NL 2” Flushing Hydrant/Sampling Point

Product Description

The model 5000-NL Flush and Sample hydrant provides both 2” flushing capabilities as well as a ½” sampling tap. The unit will fit in our model 104 lockable polyethylene enclosure for security and aesthetics.  The optional enclosure is available in both blue and green colors and is locked by a standard pad lock.

The unit is 100% non-corrosive; constructed from brass, bronze, stainless-steel and schedule 80 PVC.

The flushing outlet is 2” NST fire hydrant threads and may also provide limited fire protection. The 2″ outlet has a protective cap with a brass retention chain.

The sampling tap is a 1/2″ bronze spigot with no threads to harbor bacteria.

The 5000-NL operating valve stem is protected from direct ground contact by a PVC housing.  The main valve is operated with a standard curb key wrench. The ball valves are high-quality American made Apollo valves. The upper ball valve comes standard with a stainless steel locking handle. The inlet connection is 2” female NPT.  Inlet connection maybe customized by special order.

Freeze protection is accomplished by pumping the barrel free of water using a standard hand pump. Standard depth bury is 36” with any depth bury available.

For sample collection, the operator opens the main valve with curb-key or similar wrench.  The unit is then flushed by opening both the top 2″ ball valve and the sampling tap.  When flushing is complete, the top ball valve is closed or throttled down, and the water sample is collected through the sampling tap.

When sample collection is complete, the operator uses the curb-key wrench to close the main valve.  Then, if freezing temperatures are expected before returning to the hydrant, the operator must manually evacuate the standing water in the barrel using a suitable hand pump.

Note that “self-draining” hydrants are not allowed in situations where water samples will be collected, as the drain hole opens the unit to contamination.
