Clear Swing Checks

Simple glue or threaded valves simply connect to surrounding pipe line and cannot be taken apart. True union style swing check valves can be removed from the line and replaced later using the two union nuts on either end. This is ideal for applications where repairs and unclogging may need to take place down the road. Our Spears brand PVC swing check valves are made to last, and will stand up to years of use without corrosion or pitting.

PVC is a durable and economical material for pipe lines, especially for water handling in applications like ponds, pools, spas, and aquariums. PVC does not rust or corrode, and it is lightweight for easy shipping and installation. While the same valves are available in white PVC, many users choose clear because it benefits them to be able to see what is happening in the valve. This allows you to see when media is flowing and if the swing check is functioning correctly in your installation.
