Water heaters
Can you turn off the water to a water heater and not turn off the
pilot. I have a water heater where you have to physically light the pilot and it is a pain to restart when we get back from vacations (especially when we get back in during the night). So, I was wondering, any reason I can't turn off the water supply to the filled heater (so if it goes bad the damage is limited) while keeping the pilot on? |

I'd say that the danger of damaging the water heater is slim. But I wonder about your priorities. Shutting off the water to the heater will limit water damage to 20-50 gallons or so if a leak should develop while you're gone. The pilot, however, is an open flame. It would definitely be an unusual circumstance, but potentially devastating, if there was a gas leak. I'd be shutting off gas in my house before water if I was going to be gone for a great length of time. Jim |

When I leave I shut the water main open a main drain and open all faucets incase the heat goes out, I have 1/4 turn ball valves so it all takes a few minutes and no water will freeze, with no pressure your tank wont suddenly give away. |

i think the important thing to do if shutting water off and leaving
pilot on is to turn the thermostat all the way down on the w-heater and youll be ok. ---------------------------------------------------------------- http://www.minibite.com/america/malone.htm |

From 9+ years in the fire service (albeit 20+ years ago), my personal preference for a gas leak occurring would be while I was on vacation. Unless turning off the water will increase the likelihood of a gas leak, I view the gas leak as a random event with much lower odds that it would occur. For every gas leak explosion, there is probably 10 water heaters that break. The odds are even higher if you focus only on water heaters (and ignore the meters which tend to be high level offender, furnaces, etc.). I'd be shutting off gas in my house before water if I was going to be gone for a great length of time. This is just a couple weeks. |

That's the way I've been doing it for the last 10 years without problems - water off and thermostat to minimum. BTW, I've come back 3-4 weeks later and the water temp is comfortably warm (not hot) - thats a 40gal tank with a standard pilot and no input of cold water during that time. KC |

So, I was wondering, any reason I can't turn off the water supply to the filled heater (so if it goes bad the damage is limited) while keeping the pilot on? The only way I would do that is if you also turn the control to "pilot" so that the heater doesn't kick on. Otherwise when the heater kicks on and the valves are shut, it'll pressurize the tank and possibly release the T/P valve, thus causing the exact problem you're trying to avoid Personally I would turn the heater to "pilot" and shut off ALL the water to the house and drain it down that way if the furnace fails while I'm gone it won't burst any pipes. I wouldn't be worried about getting all the water out of the heater, *some* is good enough. I say this because the last time my house was unoccupied for more than a day or two my furnace apparently failed to light at some point during that time period and I came home to a 45 degree house (I think I had the thermostat set at 55) if it'd been below freezing, and I hadn't shut the water off, it coulda been ugly. Of course that has never happened since, Murphy's Law says that if a random, rare failure occurs it will happen of course when you're not around to correct it. nate |

KC theres tons of stuff that might be damaged in our home if it freezes, water lines, sewer traps, water lines with low spots, bottled water, chemicals and such in bottles, what about water trapped in dishwashers, washing machines, and fridge ice makers? just to name a few......... worrying too much about stuff like this can lead to ill health and early death, and then none of these trivial matters mean squat. read where a homeowner turned his water off before leaving on a trip. good safety move huh? well some kids lit a small fire on the fellows wood porch, a neighbor noticed the fire and attempted to put it out with the homeowners garden hose, which obviously didnt work since all water was off the fire got out of hand causing 50 grand in damages... that could of easily been prevented if the homowner hadnt stressed about leaving his home for the day and turning off the water. you cant be perfectly safe |

Yes you can - just set the gas valve to the "away" or "pilot" position. On a Unitrol gas valve there is a pilot position on the gas control and a "vacation" setting on the thermostat (which is for all intents and purposes "off". |

leaving the pilot going is not only ok, it's recommended. it helps keep the
burner plenum and stack dry. s "Kurt Ullman" wrote in message ... Can you turn off the water to a water heater and not turn off the pilot.

the reason was safety. the dum *******s that insisted on keeping a can of
gas next to their water heater caused this. Now they have combustible gas detectors and sealed chambers with spark ignition. There's no way a pilot uses ANY where near the amount of gas you were "quoted". steve "James Sweet" wrote in message ...

I've never had a disaster and I turn my water off every *every* time i leave
the house. Even if it's to go to the back 40 shooting range for an hour. If you only used 10,000 gallons in a 3 day leak, it must have been a small one. I used 18,000 when my garden hose blew up and we were gone for 23 hours. ('course i have 123 psi of pressure also, only on the frost free garden hose outlet out in the yard) The house is regulated to about 63. s "KC" wrote in message ...
