Check Valves slip to slip
$ 17.99
- Unfortunately many aquariums do not have these, although they should.

- If the power shuts off, and there are no check valves on submerged return lines, water will siphon from the aquarium down to the level of the return line, often flooding the sump.
- Use a check valve on each return line to prevent excess water from siphoning out of your aquarium if the power should shut off.
- Use with PVC pipe, or glue an MTP slip to barb fitting in each end and use with clear tubing.
