Test tee

A hydrologic test tee for a piping system comprising:

• an inlet having a bell at the upper end,
• a barrel below the inlet,
• a chamber below the barrel,
• an access port located on the side of the chamber, the circumference of the access port having a threaded surface,
• an access port plug, the plug having a threaded circumference capable of interacting with the threaded circumference of the access port,
• a threaded surface on the internal surface of the barrel at the top of the chamber,
• a test plug test plug having a threaded circumference capable of interaction with the threaded internal surface of the barrel,
• the test plug capable of passing through the access port into the chamber, the test plug capable of blocking the lumen of the barrel when attached to the threaded surface of the barrel,
• a test port located on the barrel above the threaded surface,
• a nipple inserted into the test port,
• a valve controlling fluid flow through the nipple, and
• a spigot having a hose connector attached to the nipple.

The process of hydrologic testing of a piping system using a test tee having an inlet, a barrel, a chamber, an access port, an outlet, comprising the steps:

• a. removing the access port plug,
• b. inserting a test plug into the chamber,
• c. closing the lumen of the barrel with the test plug,
• d. closing all drains in the piping system located above the test tee,
• e. filling the piping above the test plug with water to the highest point in the piping system,
• f. observing the water level in the piping at the beginning and at the ending of a predetermined period of time,
• g. concluding that the piping system above the test tee has integrity if there is no significant difference between the two water level observations,
• h. draining the water out of the piping,
• i. removing the test plug from the lumen of the barrel and the chamber, and
• j. replacing the access port plug.
