The improved plumbing P-trap 100 (hereinafter invention) is a plumbing fixture. The invention 100 is configured to replace a traditional P-trap. The invention 100 is configured for use with a DWV 171 (Drain Waste Vent) of a plumbing system. The invention 100 is configured for use with a sink. The sink is further defined with a drain. The invention 100 attaches the drain of a sink to the DWV 171. The invention 100 transports gray water into the DWV 171 from the sink. The DWV 171 is discussed in greater detail elsewhere in this disclosure.

The invention 100 comprises a modified P-trap 101, a second clean out plug 102, and a snake guide 103. The modified P-trap 101 transports gray water from the sink drain to the DWV 171. The second clean out plug 102 is the modification to the modified P-trap 101 that provides access to the DWV 171 side of the modified P-trap 101. The second clean out plug 102 is intended for use with a plumbing snake 161. The snake guide 103: 1) opens the second clean out plug 102; and, 2) attaches to the second clean out plug 102 to guide the plumbing snake 161 into the DWV 171. The plumbing snake 161 is further defined with a drill 162, a rod 163, and a rod tip 164. The plumbing snake 161 is discussed in greater detail elsewhere in this disclosure.

The modified P-trap 101 performs the function of a traditional P-trap. The primary function of the modified P-trap 101 is to form a conduit that transports gray water from the drain of a sink to the DWV 171. Like a traditional P-trap, the modified P-trap 101 forms a seal between the sink and the DWV 171 that prevents gas from passing from the DWV 171 into a domestic space through the sink. The modified P-trap 101 is modified with the second clean out plug 102. The modified P-trap 101 comprises an inlet 131, a dip 132, a first clean out port 133, a seal 134, and an overflow 135.

The dip 132 is a U shaped structure that forms the lowest portion of the modified P-trap 101. The dip 132 forms the gas impermeable seal that isolates the DWV 171 from the domestic space. The seal of the dip 132 is formed by the accumulation of water within the dip 132. The use of a P-trap for this purpose is well-known and documented in the plumbing arts. The first clean out port 133 is a clean out plug that provides access into the dip 132 for the purpose of removing debris that accumulates in the first clean out port 133.

The inlet 131 connects the modified P-trap 101 to the drain of the sink. The seal 134 is the portion of the dip 132 that runs from the first clean out port 133 to the overflow 135. The purpose of the seal 134 is to provide enough of a vertical head to ensure that adequate water accumulates in the dip 132 to create the gas impermeable seal. The overflow 135 is the pipe and the connecting fitting that attaches the modified P-trap 101 to the DWV 171.

The second clean out plug 102 is a clean out plug that provides access for a plumbing snake 161 to be inserted into the DWV 171 for maintenance purposes. The second clean out plug 102 is a capped aperture that provides access into the DWV 171 through the overflow 135 of the modified P-trap 101. By placing the second clean out plug 102 in the overflow 135 of the modified P-trap 101 the rod 163 of the plumbing snake 161 can be inserted directly into the DWV 171 without having to negotiate the dip 132 and the seal 134 of the modified P-trap 101. The second clean out plug 102 further eliminates having to remove the modified P-trap 101 before using the plumbing snake 161 on the DWV 171. The second clean out plug 102 comprises a guide pipe 111 and a cap 112.

The guide pipe 111 is a readily and commercially available pipe. The guide pipe 111 attaches to the overflow 135 of the modified P-trap 101 in the manner of a cantilever. The guide pipe 111 provides an opening into the overflow 135 of the modified P-trap 101 such that items inserted into the free end of the guide pipe 111 can enter the overflow 135. The guide pipe 111 further comprises an exterior screw thread 113. The exterior screw thread 113 is an exterior screw thread formed on the free end of the guide pipe 111. Threaded connections, exterior screw threads, and interior screw threads are discussed in greater detail elsewhere in this disclosure.

The cap 112 is a cover that closes off the guide pipe 111 when access to the DWV 171 is not required. The cap 112 is a capped pipe formed in the shape of a hexagonal disk. The inner diameter of the cap 112 is greater than the outer diameter of the guide pipe 111 such that the cap 112 will fit over the guide pipe 111. The cap 112 attaches to the guide pipe 111 using a threaded connection. The cap 112 further comprises a first interior screw thread 114. The first interior screw thread 114 is an interior screw thread formed on the inner surface of the open end of the cap 112. The first interior screw thread 114 matches with the exterior screw thread 113 such that the cap 112 can be screwed on to the guide pipe 111 to form a threaded connection.

The snake guide 103 is a dual purpose tool. The snake guide 103 opens and closes the second clean out plug 102 to provide access into the DWV 171. The snake guide 103 further attaches to the second clean out plug 102. Attaching the snake guide 103 to the second clean out plug 102 allows the rod 163 of the plumbing snake 161 to be inserted through the guide pipe 111 into the DWV 171. The use of the snake guide 103 allows for better control of the plumbing snake 161 and prevents the rod 163 of the plumbing snake 161 from whipping out in an uncontrolled manner during use of the plumbing snake 161. The snake guide 103 comprises a snake pipe 121, a hex socket 122, and a guide fitting 123. The snake pipe 121 is further defined with a first end 141 and a second end 142.

The snake pipe 121 is a readily and commercially available pipe. The hex socket 122 and the guide fitting 123 are attached to the snake pipe 121. The inner diameter of the snake pipe 121 is sized such that the rod 163 and the rod tip 164 of the plumbing snake 161 insert into the snake pipe 121. The snake pipe 121 is an extension structure that moves the access into the DWV 171 to a more convenient location.

The hex socket 122 is a well-known and documented device attaches to the first end 141 of the snake pipe 121. The hex socket 122 is sized to fit over the cap 112 such that the hex socket 122 can be used to screw and unscrew the cap 112 on to and off of the guide pipe 111. The hex socket 122 is a hollow device that is sized such that the rod 163 and the rod tip 164 of the plumbing snake 161 insert through the hex socket 122 into the snake pipe 121. The hex socket 122 is a commercially available device that is discussed in greater detail elsewhere in this disclosure.

The guide fitting 123 is hollow cylindrical fitting that forms a threaded connection with the free end 111 of the guide pipe 111. The guide fitting 123 further comprises a second interior screw thread 124. The interior surface of the guide fitting 123 is formed with the second interior screw thread 124. The second interior screw thread 124 matches the first interior screw thread 114 such that the guide fitting 123 can be screwed on to the exterior screw thread 113 of the guide pipe 111 to form a threaded connection. The guide fitting 123 is sized such that the rod 163 and the rod tip 164 of the plumbing snake 161 insert through the guide fitting 123 into the overflow 135 of the modified P-trap 101.
