A valve assembly is constructed for use in a filtering system including a pump and a filter with an inlet and an outlet, for example those systems used in conjunction with swimming pools. The assembly includes a valve body with a pump inlet, a filtered output, a waste-water disposal outlet, a filter inlet, and a filter outlet. Pairs of a plurality of plunger heads are positioned within the valve body to provide a plurality of modes of operation, the pairs of plunger heads being positioned within the valve body in one of a filtering mode, a backwash mode, and a direct mode in which flow from the pump is directly into the waste-water disposal outlet. The pairs can be affixed on two different interchangeable plungers or moveably positioned on a single plunger.

The invention claimed is: 1. A method of operating a filtering system including a pump and a filter with an inlet and an outlet, the method comprising the steps of; providing a valve assembly including a valve body and a plurality of plunger heads positionable within the valve body; positioning pairs of the plurality of plunger heads within the valve body to provide a plurality of modes of operation, the pairs of plunger heads being positioned within the valve body in one of a filtering mode, a backwash mode, and a direct mode in which flow from the pump is directly into the waste-water disposal outlet; and the step of providing the plurality of plunger heads includes providing a first plunger with a first pair of plunger heads thereon, the first plunger being movable between the filtering and the backwash modes of operation, and providing a second plunger with a second pair of plunger heads thereon positioned in the direct mode of operation, and the step of positioning includes positioning the first plunger in the valve body for movement between the filtering and the backwash modes of operation and replacing the first plunger with the second plunger to provide the direct mode of operation. 2. A method as claimed in claim 1 wherein the step of providing a plurality of plunger heads includes providing a plunger including a first head movable with the plunger between first and second positions and a second head movable between at least three positions with each different position of the second head defining a different mode of operation and the step of positioning includes positioning the plunger in the valve body with the first head and the second head in one of the filtering mode, the backwash mode, and the direct mode of operation. 3. A valve assembly with a valve body for use in a filtering system including a pump and a filter with an inlet and an outlet, the valve assembly including a plurality of plunger heads positionable within the valve body, pairs of the plurality of plunger heads being positionable within the valve body to provide a plurality of modes of operation, the pairs of plunger heads being positioned within the valve body in one of a filtering mode, a backwash mode, and a direct mode in which flow from the pump is directly into the waste-water disposal outlet, wherein a first pair of plunger heads are affixed to a first plunger movable between a filtering mode and a backwash mode and a second pair of plunger heads are affixed to a second plunger so as to provide the direct mode of operation, the first plunger being interchangeable with the second plunger to provide the filtering mode, the backwash mode, and the direct mode of operation. 4. A valve assembly as claimed in claim 3 wherein the second pair of plunger heads affixed to the second plunger are integrated into a single cylindrically shaped member. 5. In combination with a valve assembly having a valve body used in a filtering system including a pump and a filter with an inlet and an outlet, the valve assembly including a first plunger with a first pair of heads positionable within the valve body into one of a filtering mode and a backwash mode, the valve assembly including the improvement comprising a second plunger with a second pair of heads positionable within the valve body in a direct mode in which flow from the pump is directly into the waste-water disposal outlet, the second plunger being exchangeable with the first plunger. 6. The second plunger as claimed in claim 5 wherein the second pair of heads of the second plunger are integrated into a single cylindrically shaped member. 7. The second plunger as claimed in claim 5 wherein the second pair of heads of the second plunger include a fixed head movable with the second plunger between first and second positions and a movable head movable between at least three positions with each different position of the second head defining a different mode of operation including a filtering mode, a backwash mode, and a direct mode of operation.
