Valterra Slide Valve Washer 3"
These are the internal washers that can eventually become worn, displaced, or weakened. These are interchangeable and suited for the Valterra Slide Valves. Seals can be replaced easily. First, turn off your pumps and isolate your valve as much as possible to prevent the pond from draining. Loosen and separate the two sides of the sliding valve by undoing the bolts made of stainless steel. On each side of the 4 inch/110mm valve, you must also remove the top self-tapping screw. Clean the valve blade and internal body, remove the seals, and replace them with ones; once reassembled, apply silicon lubricating oil to facilitate movement.
