Hey guys been busy doing spring clean up around the house, so the other day i decided to clean my two stainless chimmeys, both are the supervent brand and in the spring and early summer months we get some pretty severe thunderstorms and when the rains get very heavy, water will drip in my interior stove pipes, It takes a powerful storm to do this and it's the wind that blows the water down the chimmey pipe so I took a 6ingav metal cap used and the heating and cooling industry. and placed the cap into the interior wall of the stainless pipe and put the chimmey cap back on it works perfect. I will only do this in the off season and remove the caps when time to burn again, just thought i would share this idea may help some one.
