Abstract: An exemplary embodiment providing one or more improvements includes a piping system including a test tee, the test tee comprised of a cleanout tee having an access port, a plug for the access port, a chamber, a test plug which can be inserted into the chamber and removably attached at the top of the chamber thereby blocking the lumen of the test tee. A test port is located in the test tee above the test plug, and a nipple with a valve and a spigot with connections for a hose is inserted into the test port. In testing the integrity of the piping system, the test plug is inserted through the access port into the chamber and is attached at the top of the chamber, thereby closing the lumen of the system. Other drains in the system are closed, and water is inserted into the system, optionally through the nipple. After the integrity of the system is determined, the water is drained from the system through the nipple, the test plug is removed from the chamber, and the access port plug is replaced.
