Plumbing Materials
If your pump draws water from the same level or above its own level, a check valve must be used on the suction line. A check valve must also be used on the discharge line.
If your pump draws water from below its own level (negative elevation), a foot valve must be used to prevent air ingestion.
To protect your pump from debris during suction, you can purchase a Y-strainer.
