Frequently Asked Questions

Oil-filled motors can leak oil into the pond if seals fail, harming fish and plants. Epoxy-fill eliminates this risk entirely.

No — the Pond-Mag 250 (PM250) does not include built-in adjustable flow control. All other Pond-Mag models include this feature.

Can this pump run continuously?

What type of fittings does it use?

Standard NPT (National Pipe Thread) fittings for compatibility with most pond and irrigation plumbing hardware.
