Question:

Do smoke detectors expires?

You know the inexpensive, 9 volt battery operated smoke detectors. Should they be replaced on a regular basis? When I push the test button the alarm does sound, but should you still replace them every once in a while?

Answer:

make the threads and drill the stainless the size as needed to accept the copper pipe the fittings are not necessary if you do that you may have to braze the copper elbow to mate an elbow or some type of fitting to accommodate the column .. instead of buying all that brazing equipment find a welder that will do those short jobs take you fittings to the welder [[ it costs less for you to go to his shop ]] . enjoy the spirits [[ you will have to give it away as the sale of the moon-shine is against the laws and ATF will not like you .
