solenoids

[Jack]

I know people that use the solinoid in conjunction with their RO/DI units for auto top-off but there is a warning: not reccomended for level control in the aquarium. WHY?



From J&L's website: (http://www.jlaquatics.com/cgi-bin/sh...gno=ro-kpfvkit)

Complete Float Valve Kit

The Float Valve Kit allows an RO to fill a reservoir to a desired level, then shut down water production completely.

This kit works from pressure only, no electricity.

Included within this kit is a pressure solenoid, float valve, check valve, a 1/8" elbow, a male 1/8" x 1/8" connector and 1 foot each of blue and orange tubing.

Not recommended for level control in aquariums. [/i]



I want one of these too. Can anyone answer why you can't use them for auto-top off? Too much on/off's for the solenoid?
