If a guy is earning 60K a year, but is unthrifty with his money, the next guy on 50K a year who haggles, sacrifices, and saves, ends out being the winner: actually saving more (and thus earning more than the 60K pa guy).

Besides, Homebrand do not resell the food essentials like Foie Gras, Caviar, Truffles, Lobster or Wagyu.
I read an article in the paper about dumpster diving. Apparently lots of food from the supermarkets gets tossed. Perhaps stop the clock should try that.
It depends on the type. Some do, some don't.Happy said:Does gas hot water system have anode too?
Smurf1976 said:It depends on the type. Some do, some don't.
Any gas water heater without a storage tank does not have an anode that needs to be replaced so no need to worry if you have one of those. Same with electric instant water heaters (no tank) although they are not common in residential use.
For storage tank water heaters, it depends on the type of tank.
If it is a low pressure type made of copper (not common these days) then it does not have an anode since the copper tank doesn't need one. Saxon tanks with a heat exchange coil inside (reasonably common in Queensland and have been sold elsewhere) also do not have an anode. Neither do stainless steel mains pressure (or low pressure) tanks - these are mostly used on some types of solar hot water system.
But if you have one of the popular "Rheem", "Dux" or similar tanks (including Quantum and most SolaHart tanks) then it DOES have an anode. The tank itself is made of steel and coated with enamel. Steel is cheap and strong but rusts easily in water so a sacrificial anode is fitted to provide protection against this.
Without being too technical, it sets up a small electrical current (literally like a battery) to prevent corrosion. It is NOT a chemical additive to the water as many wrongly assume so nothing to panic about there. However, the principle of operation is to transfer the point of corrosion from the tank itself to the replaceable anode. This means that the anode will be gradually eaten away until there is none left. Once it's gone, the tank rapidly corrodes and in due course you end up with it bursting.
The same principle is commonly used to protect bridges, oil rigs, pipelines etc against corrosion. Indeed around some cities you'll see little plates on the ground showing the location of anodes protecting water and gas pipes etc.
Strictly speaking, it is a job for a plumber to replace it but I'll post the details of how to do it if anyone wants to know. Cost is about $50 for the anode plus labour.
Physically, the anode is a long rod about the same thickness as a broom handle and nearly as long as the tank's height. You'll need space above the tank roughly equal to the height of the tank itself since the anode will NOT bend and can NOT be taken out at an angle (a small hole in the ceiling will do if the tank is installed in a cupboard and you don't need to enter the roof - I'll post the details if anyone wants to DIY- takes about 15 minutes).
Changing the anode greatly prolonges the life of a water heater that has one. Mine is 28 years old and still going fine whereas it's common for them to fail after 7 - 10 years if the anode is not replaced. Since it costs you $1000 or so and causes considerable inconvenience when the tank fails, maintenance is worthwhile.
Another point on water heaters, if possible you should drain and flush the tank every year or so to remove sediment. Most new ones have no facility for doing this but on older units there is often a bolt that unscrews on the side near the bottom. This is simple DIY as long it's not inside (you'll be draining ALL the water out). I'll post details if anyone wants to know how. The point is to remove sediment which is corrosive (applies regardless of what type of tank it is). You'll be truly amazed at just how much filty brown water comes out if it is a few years old and has never been flushed.
For mains pressure tanks (Rheem, Dux, Quantum etc) you could just turn the power / gas off and turn a few hot taps up full until you've flushed about 3 times the volume of the tank through. Assume a flow rate of about 15 litres / minute if the pressure is reasonably good. This will stir up and remove most of the sediment but obviously you're going to waste 500 - 1200 litres of water so not recommended in areas where water is scarce at the moment. Leave the power / gas off for an hour or so after turning the taps off so that any remaining sediment settles (otherwise it could block the relief valve).
On the subject of relief valves, it should drip ONLY when the water is actually being heated. If it's dripping all the time then it needs replacing (you're paying for all that wasted hot water).

I used to have tightwad friends.
One day, one of them bought something from a store nearby for $11.70. The next day, their junk mail showed a store across town had them for $9.70. What did they do? They took the first one back for a refund (used $1 in petrol & wasted 35mins driving to the shop, parking, walking in & waiting for refund) then.... drove 20km across the city to buy the cheaper one (used $4 in petrol & wasted 2hrs 25mins).
He was so proud of himself cos he saved $2 on the item.
I asked him how much he would have made by going to work for those 3 hours.....he said about $45....then I told him to add on the $5 in petrol.....hey presto, you just spent $50 to get $2 back.......what a legend.....can I be a stupid tightwad like you?
On two occasions I've been to Wollies and walked out with what I wanted without paying a cent. Just have to catch them at it and then it's free...money tree said:we get shafted at woolies at least once a week but they get away with it cos its too much trouble.....unless you catch em in the act, then the item is free
