The Dielectric Union
how come I wasn't told about this
This is a dielectric union. This device electrically separates the water heater from the household piping. http://www.hammerzone.com/archives/p...n_de/intro.htm |

We normally just don't spout off information unless asked! Someone a while back had commented on the corroded mess he had on the water line of his water heater. I recommended dielectric unions then.

The Dielectrics have a union? What sort of benefits does it offer its
members? |

Lots of good info and photos, very useful for the amateurs. The book is part of Taunton's series "For Pros By Pros" but I'm not sure the pros would actually need it. "The Complete Guide to Home Plumbing" by Black & Decker is also nice for filling in some gaps from the first book (e.g. extensive rundown on pipe types and uses). Both books are dirt cheap compared to potential repair bills. |

This is just a nipple with a plastic sleeve, that will not insulate from the current. You can check this easily with a DMM. Simple continuity test. Granted I am sure it would not corrode nearly as quickly, as a unlined nipple. But as soon as water gets between the sleeve and the nipple. There is a space between the plastic and the nipple from molding. Plastic shrinks as it cools from the molding process. It will start corroding. Rick R. |

I've been looking for a solution to the galvanic corrosion for many years. My very hard water after softening is a very conductive electrolyte. Using brass nipples supplied with a water heater, I got galvanic corrosion of the tank near the nipples and early tank failure. Switching to galvanized nipples, the nipples soon corroded at the dielectric connection. The short path across the insulation is apparently easily bridged in conductive water. But this is an improvement -- better to replace nipples every year or so than an early failed heater. Plastic lined nipples seem to be new to the market. They do provide a much longer conductive path though the conductive water. I installed a pair a year ago. The early signs of corrosion I experienced with the previous steel nipples have not appeared and I am hopeful that this will be a substantial improvement over the previous solutions. It will take some time to conclusively prove their value but I am hopeful. SJF |
