ok i have a boxxer 421 and for some reason i cant find the problem on why is it dumping water as soon as you fire it up water starts to flow into the recovery tank ive clamp down on the line hi temp control 180 and water still flows into the tank then i clamp down on the line that gos to the dema solenoid and still water flows to the tank the unit runs good and dose the test with temperature adjustment when it hits its temp the pressure will drop then back up again the way its suppose to do also keep in mind that chemical jug is going empty fast these are the two things that are my issue its causing me very low heat and i dont even need to open the flow meter and it will draw chemical from the jug i already put a new diaphragm new hi temp180 valve also the two new check valve so my next move is to replace the 3 way valve can any one tell me whats going on thank you
