Where would I add a winterization kit or use an existing fitting to add antifreeze to my system? Is the white plastic circle to the left of the pump a filter? Thanks
Where would I add a winterization kit or use an existing fitting to add antifreeze to my system? It has to be added on the inlet side of the pump. If you get another hand threaded fitting and about 4 feet of appropriate sized hose, you can switch out the filter side with the short piece and stick the hose in a jug of RV antifreeze.
