Check valve required?

[jccams]

I am going to remove a leaking tablet feeder from my pool plumbing (don't use it anyway). Currently there is a check valve between the feeder and the heater I assume to prevent high concentrations of chlorine from reaching the heater. My question is whether or not I need the check valve in this location any more since there will be no chlorinator.

Unless you have a solar heater, you can remove the check valve.

Just a good ole gas heater, thanks Jason that's what I thought.
