Lead Pot Spout Leakage

Leaking from the valve on a Production Pot is usually caused by dirt in the valve seat.  Another reason for leakage is that the pot had lead in it before being heated up.  During the heating process, the lead in the pot expands and temporarily pulls the valve stem out of the spout.  This results in spout leakage until such time as the lead turns molten and the valve stem reseats.   Usually, twisting the valve rod side to side with a screwdriver in the slot provided at the top of the valve rod will solve the problem.  

The only home remedy that can be used is to lap the valve rod in place with valve grinding compound. This is available at automotive supply stores. Remember also to keep the melt clean by frequently fluxing. This will limit the amount of sediment that finds its way down to the valve seat. Due to the corrosiveness of lead alloys at elevated temperatures, it is quite difficult to keep the valve in perfect leak proof condition.

A slow drip can be considered normal after some use. If it is excessive, we can reseat the valve. Return your pot along with $8.00 to cover the cost of shipping and handling.
