Let me correct my statement. ....there are acutally four valves - hot, cold, bypass ball valves and one check valve on the COLD side of the water heater.
Also, let me give a word of advice.... DON'T USE BLUE HAWK COMPRESSION FITTINGS WITH PEX UNLESS YOU ARE ONLY USING THEM IN A FEW LOCATIONS!!!! I tried to replace all my ball valves and water line (including bypass) at the water heater with those fittings and leaked, leaked, leaked!
I didn't have a lot of room to work so I didn't want to use the crimp fittings. I ended up removing all my ball ball valves to minimize the fittings and all seems good now. ...of course I'll have to blow out the lines this fall.
