Common questions

Before you order.

If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.

What if I'm not sure this is the right product?

Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
