HOT WATER FLOW BLOCKED
House is 62 yrs old... Water heater went out. Replaced it.
Now, the hot water won't flow to the kitchen, bathroom sink, or bathtub. Cold water runs fine. The debris in the pipes has blocked the flow (water heater is running perfectly). Is there a way to back flush or blow the pipes out. Or, do I need to repipe? I now live in a cold water flat |

The debris will go back into your brand new heater but there shouldn't be much of it - you'll get rid of it next time you flush the heater in a few years. * Shut down the heater, especially if it's electric * Close the heater's cold water inlet valve * Do *not* open the pressure relief valve * Connect a garden hose to the drain valve at the bottom of the tank and put the other end of the hose into a toilet or outside where noone can come in contact with the hot water that will come out. * Open the drain valve * Go to the faucet that does not work and block it. If it has an aerator, you can unscrew it, put a dime coin and screw it back. Else just wet a rug and hold is against the faucet's outlet really tight. * Open hot water, then cold water at the faucet, both all the way. * It will probably take a just couple seconds of cold water entering the hot water lines through the mixer in the faucet to push any debris/sediment in the lines out. You should hear water rushing through the faucet, hopefully not much of it fountaining all over the kitchen -- * Close the cold water valve on the faucet but not the hot. * Restore the faucet (i.e. remove the dime etc.). * Close the drain valve on the heater, remove the hose. * Open cold water inlet on the heater and watch the water bubble out of the kitchen faucet. When the water flow becomes normal, close the hot water valve. * Turn the heater back on That should do the trick. ------------------------------------- /_/ ((@v@)) NIGHT ()::) OWL VV-VV |

Another option, since the OP implied that the water doesn't flow to any room, would be to open the pipe at the farthest point from the heater before it branches to the other rooms. One would assume that the blockage has to be before the first junction. Perhaps it could be snaked or rattled or back flushed from there. In my house, if I had no hot water to *any* fixture, there's only about 6 feet before the first branch, so I wouldn't have too far to look. Any chance that the debris is actually clogging each fixture? Perhaps the OP should check each aerator before screwing around with the pipes. |

I wondered about, but didn't question, the connection between replacing the broken hot water heater the subsequent appearance of enough debris in (only?) the hot water pipes to block them. I guess just banging them around could have caused it to happen. I think anytime you disrupt the normal flow of water whatever obstructions there are can then dislodge, travel down the pipe to a place where it's almost blocked, and lodge there. Kind of like what happens to us with coronary artery disease. I've seen houses where similar happened, like draining the water for winterization. In this case, the pipes were partially drained, air introduced, probably restarted with a surge instead of slowly, etc. producing turbulence, which then can dislodge all the debris inside. Another option, since the OP implied that the water doesn't flow to any room, would be to open the pipe at the farthest point from the heater before it branches to the other rooms. One would assume that the blockage has to be before the first junction. Perhaps it could be snaked or rattled or back flushed from there.

Very likely the aerators will need to be cleaned anyway, so taking them off to check now would be a good idea. |

However, shutting off the service valve to the water heater and opening the drain, THEN connecting from the hot to cold will do it. Just cap the laundry tub faucet, open the hot water tap, then open the cold, and the cold water fill force it's way back into the heater, forcing water out the drain of the heater (which you should have a hose on, running to the laundry drain). |

The term "cold water flat" may just be a blast from the past as that was a common term for low-end apartments here in the US. I could quote Wiki, but I avoid that at all costs, so I'll point you here instead: http://ask.metafilter.com/175061/Wha...coldwater-flat Cold water flats were common in the tenements of NYC, Chicago, Detroit, etc. in the early-to-mid 20th century. They were referred to as such. |

Back flushing won't catch that stuff. Try one at a time, easiest first and see how it works out. Once the facet is apart, open the shut-off valve and flush a bit of water before assembly to clean anything else in the pipe leading to it. |

I now live in a cold water flat You should be able to flush it out by reversing the flow. There's a good chance it will work since the blockage is very recent. The debris will go back into your brand new heater but there shouldn't be much of it - you'll get rid of it next time you flush the heater in a few years. * Shut down the heater, especially if it's electric * Close the heater's cold water inlet valve * Do *not* open the pressure relief valve * Connect a garden hose to the drain valve at the bottom of the tank and put the other end of the hose into a toilet or outside where noone can come in contact with the hot water that will come out. * Open the drain valve * Go to the faucet that does not work and block it. If it has an aerator, you can unscrew it, put a dime coin and screw it back. Else just wet a rug and hold is against the faucet's outlet really tight. * Open hot water, then cold water at the faucet, both all the way. * It will probably take a just couple seconds of cold water entering the hot water lines through the mixer in the faucet to push any debris/sediment in the lines out. But it will take longer to push debris back to the water heater and flush it from there. Probably more than twice as long as it takes for hot water to get to that faucet normally. |

If the heater connections are flexible, it could be worth disconnecting the hot water connection from the tank and flushing into a bucket rather than into the heater. |

Cold water runs fine. The debris in the pipes has blocked the flow (water heater is running perfectly). Is there a way to back flush or blow the pipes out. Or, do I need to repipe? I now live in a cold water flat You did clean out the aerators on those faucets, right? Those clog right away. If you dont know what they are, they're the screens on the ends of the faucets. They unscrew. Unscrew them and clean them. Let the water flow for a few minutes before you put them back on. If it's actually the pipes, shut off the cold water valve at the water heater. Unscrew the union for the hot water pipe above the tank. Hook your garden hose to an outdoor spigot, or laundry tub in your house. Hold the hose tight against the faucets, with the aerator removed, and faucet HOT turned ON, or use a hose with clanmps to get a tight seal. Have a helper turn the water on and off at the spigot (water source). Do this at all the faucets that are clogged. Besides the aerator, the other thing that regularly clogs are the shutoff valves under the sinks, and the supply tubes. Sometimes just removing them will solve it. Replace these shutoff valves and supply tubes if needed, or just unclog them. |
