Abstract: A method and apparatus for admitting liquid from a draining surface into a drain conduit and for preventing discharge of waste gas from the drain conduit into the atmosphere in response to a higher pressure in the drain conduit than at the draining surface. The method and apparatus typically are for use draining floors, basements, roofs, countertops, exterior paved areas, and surfaces draining into line that could discharge waste gas back into the environment. The invention provides floor drain assemblies and check valves with good drainage performance with out the use of P or U-traps, and is particularly well suited for use when drainage occurs irregularly. Floor drains according to the invention comprise check valves adapted for disposition within floor drains, the check valves generally comprising spring-loaded stops, elastic diaphragms, or sheath valves. Check valves according to the invention are preferably installable in existing drain structures, and are easily removable.

Abstract: A water closet fitting installation assembly for installation and optional testing of a water closet fitting within a poured, permanently set floor. The assembly permits the fitting to be rapidly and efficiently installed flush with the floor surface, without risk of fouling the drainage system or blocking drainage of water from the system with slopped or mispoured floor material such as concrete; facilitates mounting and placement of a water closet stool. Optionally the system further facilitates pressure testing of the drain system after the fitting has been installed, without the necessity of placing permanent structures or other blockages in the drain system.

Abstract: A water closet fitting comprising a removable test baffle allows a water closet drain system to be tested for fluid tight integrity after the fitting has been installed in a poured, permanently set floor such as concrete. The test baffle is removably attached to the fitting, preferably by interfering fit between the test baffle and the fitting, for efficient installation, and comprises means for removing the baffle entirely from the fitting and the drain system after the completed system has been permanently installed and successfully tested. A preferred embodiment of the baffle is flexible, has a diameter greater than that of the central drain system, and comprises a central dome to enhance its pressure resistant characteristics. The flexibility of the baffle allows it to be removed through the installed drain system after the system has been tested successfully.

Abstract: An improved system for the non-destructive testing of the fluid tight integrity of an installed fluid transfer line such as a drain pipe or vent and wastewater system of a building. A removable test baffle is held in place between ends of adjacent sections of an installed fluid transfer line to isolate a portion of the line for testing. The test system comprises a baffle carriage, a removable test baffle, and a sleeve adapted to engage the outer surfaces of the adjacent sections to seal the junction and the test installation from leaking and optionally to provide one or more gaskets between the section ends and the baffle carriage. In optional preferred embodiments of the test system the baffle carriage is an integral part of the sleeve. Preferred baffles for use with the invention are flexible, of larger diameter than the fluid line, and comprise dual-gasket sealing means and means for removal of the baffles from either side of the test seal.

Abstract: An improved system for the non-destructive testing of the fluid tight integrity of an installed fluid transfer line such as a drain pipe or vent and wastewater system of a building. A removable test baffle is installed in a seat extending radially into the sidewall of a pipe or other fluid transfer line to isolate an installed portion of the fluid line for testing. The test baffle comprises a pair of gaskets to improve the effectiveness of the baffle in sealing or isolating the line and a domed central web to facilitate testing at increased pressures. The test baffle optionally further includes a lightweight, low cost ribbed construction and a means for removing the baffle from either the convex or concave side of the dome without leaving behind any portion of the baffle to impair fluid flow within the line. On removal, the baffle is flexed into a saddle shape and removed from the line without need for dismantlement of the line.

Abstract: An isolation diaphragm assembly designed to be installed in a standard tee, Y or coupling in a conduit to isolate one portion of the conduit from another. In its initially installed condition, the isolation diaphragm assembly provided a seal for isolating portions of conduit systems for pressure testing. Once the testing procedures are complete, the test diaphragm, being larger in diameter than the interior diameter of the conduit, is flexed into a saddle shape to permit its removal from a gasket and due to the decreased dimension, may then be drawn out of the conduit, leaving a fully unobstructed flow path.

Abstract: A conduit isolation baffle assembly designed to be installed in a conduit system such as a vent and wastewater system of a building. The flexible baffle is installed in a groove having a sidewall and seat formed in the interior surface of a conduit to isolate the system for testing. Once the testing procedures are complete, the baffle is flexed into a saddle shape so that it is removable from the conduit without disassembly.
