POOL FILTER MPV TOP & O RING QUALITY ORIGINAL SERIES 2 Product Description: The Pool Filter MPV Top & O Ring Quality Original Series 2 is a replacement multi port valve top designed for compatible swimming pool sand filter systems, including Quality SuperFlo Series 2, SuperFlo MK2, Bluchem and Blue 52 filter models where the valve body and fitting match. The MPV top is the control section of the sand filter valve. It allows the pool owner or service technician to select how water moves through the filtration system. A working MPV top is important because it controls whether the system is filtering normally, backwashing the sand bed, rinsing after backwash, sending water to waste, bypassing the sand bed or closing the valve. Over time, the top section of a multi port valve can become worn, stiff, cracked or difficult to turn. The internal sealing surfaces and O ring area may also wear, which can cause leaks or poor valve selection. Replacing the correct MPV top can help restore normal filter control without replacing the full sand filter, provided the lower valve body and filter system are still in good condition. This Series 2 MPV top is supplied with an O ring, which helps create the seal between the MPV top and the compatible valve body when fitted correctly. Before installation, the old O ring and valve seating area should be checked and cleaned. The new O ring must sit correctly and must not be pinched, twisted or overtightened. The Filter position is used for normal daily filtration, where pool water passes through the sand bed and returns to the pool. The Backwash position reverses water flow through the filter to flush dirt out through the waste line. The Rinse position is used after backwashing to settle the sand bed and flush remaining dirty water to waste before returning to filter mode. The Waste position sends pool water directly out through the waste line without returning it to the pool. The Bypass or Circulation setting allows water to move without passing through the sand bed where the valve design supports it. The Closed setting shuts the valve and must not be used while the pump is running. Because MPV tops can look similar but differ in fitment, this product should be checked carefully against the existing valve. Confirm that it is the correct Series 2 type for your filter, not an MK1 or unrelated multi port valve top. Check the bolt pattern, O ring seat, selector handle layout, valve body shape and filter model before purchase. FAQs What is an MPV top on a swimming pool sand filter? An MPV top is the upper control section of a multi port valve. It allows you to choose different sand filter functions such as filter, backwash, rinse, waste, bypass or circulation, and closed where supported. What does this Quality Original Series 2 MPV top include? The product name states that it includes the MPV top and O ring. Which filters is it made for? It is designed for compatible Quality SuperFlo Series 2, SuperFlo MK2, Bluchem and Blue 52 swimming pool sand filter systems. Why must I check compatibility before buying? MPV tops can look similar, but different versions may have different bolt patterns, sealing surfaces, handle layouts and valve body shapes. Using the wrong MPV top can cause leaks or incorrect valve operation. Is this a universal MPV top? No. It should be treated as a Series 2 replacement for the compatible filter systems listed. Always compare the old part before buying. What does the filter setting do? The filter setting is used for normal daily pool filtration. Water passes through the sand bed, where dirt and sediment are trapped before cleaner water returns to the pool. What does the backwash setting do? Backwash reverses water flow through the sand filter to dislodge dirt and send it out through the waste line. What does the rinse setting do? Rinse is used after backwashing to settle the sand bed and flush remaining dirty water to waste before returning to filter mode. What does the waste setting do? Waste sends pool water directly out through the waste line. It is commonly used when vacuuming heavy dirt to waste or lowering the pool water level. What does bypass or circulation mean? Bypass or circulation allows water to move without passing through the filter sand bed where supported by the valve design. What does closed mean? Closed shuts the valve. The pool pump must not be operated while the valve is in the closed position. When should I replace my MPV top? Replace it when the top is cracked, leaking, stiff, hard to turn, not selecting positions correctly, or when the handle and sealing surfaces are worn. Can I install this myself? Some pool owners may be able to fit it, but correct seating and sealing are important. If unsure, ask a pool technician to install it.
