All Intex products are designed to be compatible with other Intex products. If you choose to connect a competitor's product to an Intex product, we cannot guarantee their proper operation or offer any parts to connect someone else's product. Intex filter pumps are primarily designed for Intex above ground pools. This concept is based on the fact that the bottom of the pool and the base of the pump are at the same level. If you place the filter pump below or above the level of the pool bottom, we cannot guarantee that it will function properly and will not, for example, over-aerate, etc. At the same time, Intex uses a standard connection with a diameter of 32 or 38 mm, which is designed primarily for Intex products. We do not offer adapters and reducers for other dimensions.
