Drainage valve pipe tap assembly

A drainage valve and pipe tap assembly comprising:

• a valve body;
• the valve body having a first end and a second end;
• a passageway located in an interior of the valve body, the passageway directing the flow of water from the first end of the valve body to the second end of the valve body;
• a screen located between the first end and the second end of the valve body, the screen having multiple openings sufficiently small to prevent the flow of dirt and other contaminants from flowing therethrough but sufficiently large to permit the flow of water therethrough;
• a resilient drain plug located within the drainage valve body between said first screen and the second end for blocking off the flow of water under a water pressure through the body and against the drain plug and for allowing the draining of water through the body and out the second end when the water pressure is cut-off thereby allowing the drain plug to open;
• a male thread, the male thread located on an exterior of the valve body for rotational engagement;
• a pipe tap, the pipe tap having a first end and a second end,
• a chamber connecting the first end of the pipe tap to the second end of the pipe tap;
• a female thread, the female thread located within an interior wall of the pipe tap for engaging the male thread of the valve body;
• and
• a cutting tube having a tapered end, located proximate the tapered end is a water inlet for receiving water therethrough, the cutting tube securely attached to the first end of the pipe tap, the cutting tube having at least one tooth located proximate the tapered end for cutting the sidewall of a pipe.

A method of assembling a drainage valve and pipe tap assembly comprising the steps of:

• providing a drainage valve having an inlet, an outlet, a passageway, and a resilient drain plug located therein;
• providing a pipe tap having a first end, a second end, a hollow interior, a handle having a hollow interior located at the second end of the pipe tap, a cutting tube located at the first end of the pipe tap;
• placing a screen between the first end and the second end of the pipe tap;
• and
• attaching the drainage valve to the pipe tap by inserting an end of the drainage valve into the second end of the pipe tap to thereby form a freeze proof drain thereby allowing the drainage valve to move between an open and closed position when the water pressure is relieved and applied against the drainage valve.

An in situ method of assembling a freeze proof drain comprising the steps of:

• attaching a housing to a pipe;
• attaching a pipe tap to the housing;
• forming a hole in a sidewall of the pipe by rotationally driving a cutting tube of the pipe tap through the sidewall of the pipe;
• placing the cutting tube so that a screen located on the cutting tube is positioned within an interior of the pipe;
• and
• inserting a drainage valve having a resilient drain plug located therein into a chamber in the pipe tap to form a freeze proof drain thereby allowing the drainage valve to move between an oven and closed position when the water pressure is relieved and applied against the drainage valve.

An in situ method of assembling a freeze proof drain system comprising:

• attaching a tap housing to a pipe;
• extending a tap having a screen thereon through a sidewall of the pipe;
• and
• inserting a drainage valve into the tap to form a freeze proof drain system thereby allowing the drainage valve to move between an open and closed position when the water pressure is applied against the drainage valve.

A tool for forming a hole in a plastic pipe consisting:

• a hollow shaft having a first end and a second end, said shaft having a tapered body;
• a cutting tooth located at the first end of the shaft for cutting a sidewall of a pipe;
• a screen located between the first end and the second end of the shaft, said screen preventing a flow of dirt and other containment therethrough while simultaneously allowing for a flow of water therethrough;
• and
• a handle, said handle to the second end of the shaft, said handle enabling a user to grasp and rotate the shaft to form a hole in the sidewall of the pipe.
