I do have an overflow - but appreciate the observation.Looks nice and neat. Is there a way to drain water? I don't see an area where you can connect a vinyl hose to in order to drain water if needed. You may have an overflow built in in which case no big deal (a pump would be used for larger volumes of water drainage if needed).
Revised following input Not 100% but directional improvement made Almost 3 feet from Heater, SWC Vertical 10 inches straight before SWC By-Pass for heater and by-pass for SWC. Thank you to TFP members for the guidance.
Thank you - will get that setYou need to have a check valve on the output side of the heater before the T. As it is now your bypass will work as long as your heater holds pressure and does not leak. If your heater leaks and does not hold pressure without the CV water will flow through the bypass and back into the heater output and out the leak.
