Abstract
An adjustable P-trap for a sink is presented. The P-trap has a semi-rigid J-shaped tube with a diameter between one inch and two inches. The J-tube has a long end to connect to a sink drain and a short end to connect to a wall drain. When the long or short end do not reach the appropriate drain an extension tube is cut to length during installation. The long end of the J-tube has threads constructed to receive a threaded adapter and the short end of the J-tube also has threads constructed to receive the extension tube. When a first hose clamp (4a) to clamp the threaded adapter in the long end of the J-tube. When the extension tube is used, the extension tube is mated with the appropriate end and hose clamp is used to secure the two together. The extension tube is then mated to the sink or wall drain.
Description
- The present disclosure relates generally to p-traps used in plumbing, and more particularly to adjustable p-trap.
- The plumbing and construction industries have for a long time understood the necessity of employing a trap, to act as a vapor barrier, between an open drain hole in a sink, for example, and a conduit to a sewer system or septic holding tank. Such traps are configured to retain (trap) an amount of water in a U-shaped bend which is sufficient to form the vapor barrier against noxious sewer gases entering living space through an otherwise open drain. Such gasses are unhealthy and can cause sickness.
- A conventional P-trap is formed from generally tubular drain fittings, which may be fabricated from either metal or plastic. A conventional trap is typically formed with the U bend to which is attached, for example, a 90-degree elbow at the outlet leg of the U. This elbow defines a generally horizontal outlet which can then be connected to appropriate drainage tubing which is in turn connected to a sewer or septic system for the disposal of liquid wastes. For P-traps made from plastic fittings the inlet leg of the U is typically solvent welded or frictionally coupled to a drain pipe which may for example extend down from a sink or bathtub drain.
- Typically, between the 90-degree elbow and the U is a joint which may be either a solvent joint or may be a detachable joint held together by a threaded connector. The other outlet end of the elbow is also typically solvent welded to the outflow drainage conduit.
- Ideally such a P-trap is installed as follows. First the drain pipe from the sink and the drain conduit connecting the sink to the septic or sewer system are roughed in to an approximate location. The ends of these pipes will be generally in the same area, but not attached. Then the P-trap is installed between the free ends of the two pipes. The P-trap, comprising the elbow and the U-shaped tube tightly threaded together, is first solvent welded at one end and then solvent welded at the other end. Then the threaded joint can be undone or relaxed if needed for further manipulation of the pipes.
- However, what more typically happens is that the installer positions the P-trap in place between the free ends, and then trims the ends of the pipes to an appropriate length to accept the P-trap there-between. The location of the trap is often very awkward; the pipes may be crammed together under a sink in a vanity cabinet for example. So, typically, the installer will undo the threaded connection, and then solvent cement or glue or solvent weld, individually, the separated elbow and the u-shaped tube to respective free ends of the pipes. Then, the installer uses the threaded connector to draw the two components into a sealing relationship. While easy, this method is problematic. It is very difficult to ensure the two fittings are both attached perfectly in the same plane.
- Further because they are separated at the time they are attached, it is difficult to ensure that the ends are sufficiently close to permit the connector to easily couple the two ends together. As a result, it can be difficult to make a leakproof joint at the connection between the U-bend and the 90-degree elbow, because to do so requires precise positioning of the two solvent welded fittings relative to one another at a time when they are separated. According to preferred procedures, the threaded connection should be made tight between the elbow and the U-shaped bend before welding the components in place.
- However, where the elbow and U-shaped pipe are disconnected and each independently solvent welded onto their respective drain pipe connections misalignment usually occurs. The threaded coupler can compensate slightly for misalignment because of the compression provided by the threaded coupler onto a seal and the slight resiliency of a plastic pipe system. To rely on the inherent resiliency of the pipe system however essentially introduces a strain into the system.
- A P-trap joint which is under pressure may not seal properly or worse, it may seem sealed but over time due to the strain introduced by misalignment may fail later. Alternatively, if the misalignment is large, the pressure generated by the threaded coupler as the components are clamped together can be enough to cause a cracking or opening of other drain pipe connections in the piping system. What is required, therefore, is a P-trap assembly which couples or connects to form a good liquid tight seal even when the components are slightly out of alignment without creating unacceptable stresses in either the P-trap assembly or any other part of the plumbing system.

FIG. 1 shows the prior art P-trap assembly. The P-trap is a J-tube 50. The J-tube 50 as a long end and a short end. The long end of the J-tube is anupper squeeze coupling 51. The short end of the J-tube has alower squeeze coupling 52. Theupper squeeze coupling 51 of the J-tube is typically connected to the drain of a sink (not shown). Thelower squeeze coupling 52 of the J-tube 50 is typically coupled to a pipe leading to the sewage system to remove waste and waste water from the sink. The J-tube 50 when in place and water is flowing into the J-tube 50 forms a P-trap to keep odors and gases from leaking back through the sink. - One problem is that the prior art, as shown in
FIG. 1 , requires an exact length between the sink drain and the wall drain. If the J-tube 50 needs to be altered in length, the J-tube must be cut and either or bothupper squeeze coupling 51 and/orlower squeeze coupling 52 will be removed. The threaded coupling for theupper squeeze coupling 51 and/orlower squeeze coupling 52 would be removed and a coupling to either the sink drain or wall drain would be compromised. -
