From experience, when the element in the cylinder blows, the fuse goes off with a hell of a bang. Also, you may need a very large box spanner if you have any thought of replacing the element yourself. Best to get an electrician to check things out first. Our cylinder was installed in 1960 and is still going strong. Elements nowadays don`t last anywhere as long as the old ones either. Cheers: pipercub |

If you open this valve you will need to loosen and remove the water pipe outlet at the top of the cylinder to let air in as the water exits. Failure to do this will collapse the copper cylinder due to the vacuum created. Good luck, with the correct tools and some common sense it is not a difficult job. :) | Richard (739) | ||
| 667609 | 2008-05-11 10:02:00 | And if you do decide to change the element, make sure you loosen the element SLIGHTLY BEFORE emptying the water. The reason for this, is the weight of the water inside stiffens the internal copper tank, if it's empty and the element thread is stuck, you can rip the side of the tank out and then you are up for a full replacement cylinder. |

| 667610 | 2008-05-11 14:22:00 | How much does it cost to get a new cylinder installed and hooked up to a wetback The wetback may prove a bit hard. A law was passed that to get a wetback you need at least 2 acres of land (so rural homes only really). It sounds silly but the argument was people tend to burn more wood if they have a wetback thus adding to the pollution and global warming. Which IMO is garbage as it "kills two birds with one stone" if you know what I mean. You'll have to check though, since you mentioned it is already installed just not hooked up you may be able to still get it done. |

| 667612 | 2008-05-11 20:52:00 | Thanks all I decided to call a plumber this morning (well at around 9am when they are actually at work), guess what I had a lovely hot shower, the shower controller had to be moved a shade further round than normal, but its hot again. I still going to call the plumber though as something is definitely wrong |

| 667613 | 2008-05-11 21:55:00 | It's probably the thermostat. Unless the rusted bottom of the tank was from water running down the vent pipe from the roof, ask him if the tank is OK. If the felt is damp plan to swap one of your children for another tank. |

| 667614 | 2008-05-12 01:05:00 | Just another thought Nigel. I had a problem about 3 years ago with similar problems to your's. It turned out to be the pressure contol valve on the hot water cylinder. The diaphragm had developed a bit of a crack and the large washer at the back was pretty well knackered due to sand and silt. Sometimes we would have hot water sometimes not. I drained the cylinder, replaced both the diaphragm and washer and have had no problems since. I might be wrong but I believe that unless you know a friendly plumber you have to replace the complete pressure unit, whether you are allowed to do it yourself is another headache. Being rural we learn to do these things ourselves. Just another though Nigel, check the overflow pipe on the roof, that could be an indication of a stuffed diaphragm allowing the hot water to be expelled and a constant flow of cold water coming in to the tank. |

| 667615 | 2008-05-12 02:43:00 | Hi again Nigel. Sorry I didn't see the photo's of the corrosion on the underside of the tank. From what I can see I suspect you have a leak somewhere above the actual corrosion point which may wicking down between the outer and inner sleeves. If you can't see any obvious signs of moisture under the tank try and look further up, even feel the cladding around the tank for moisture. Regards Gordon. |
