Galvanised water pipes
« on: October 27, 2012, 02:12:34 PM »
I have a gas hot water heater (low pressure) that is severely leaking.  I want to change it to an infinity type water heater but have been told that before doing so need to change the water pipes under the house as well because they are galvanised and wont accept the change in pressure.  We also have water pipes coming around the outside of the house and one of them is rusty and just holding.  I approached a plumber about fixing it but he was unhappy to touch any pipes that go through the wall. 

Do i need to upgrade all the water pipes?
What is the danger with old pipes going through walls?  Am i looking for a specialist for some of this job or will any plumber and gasfitter be able to do the job?

Thanks

It would be pretty unusual for the hot water line to be galv they are probably in copper so they should handle the pressure change without a problem. The galv lines in cold therefore wouldn't change in pressure unless the whole property is limited. I would recommend installing a line strainer before the infinity if you wish to use the galv pipes as the rust particles will block up the infinity pretty quickly. Any competent Gasfitter should be able to do the job and remember to check that they are licenced to do the job.

hi Bakeit, yes you will need to replace all those rusty galv pipes, they will leak when you mains pressure the hot system, i suggest you get your plumber to price a complete upgrade too you pipe work, or you run the risk of leaks from old pipes for yours to come which will cost you far more.
Those pipes will be causing you all sorts of other problems with debris blocking filters and damaging any new tapware you have.
Do it once and do it right :D

I believe in doing a job once and right. !

And Bakeit, bear in mind that quite a large % of the plumbers price will be bouying up a corrupt industry Board..... who has recently tried to avoid paying tax by spending $24 000 of these law abiding plumber's annual contributions, on lawyers to hold on to its charity status,(yes a charity) which, as it is meant to be a "not for profit" organisation and you only pay tax on profit, is a misnomer if you don't make a profit....and they made heaps of profit this year.....unbelieveable but all totally true.

Remember to "ask for the card".....because it costs $4500 to get...

One year they paid for an all in partners included trip to Melbourne, funded by us tradies.....but ultimatly by the public because we have to pass on this huge cost.....do you know of any other jobs where you pay $4500 to go to work?

Did you know Bakeit that on average for each licence it costs an already fully qualified, time served, plumber, gasfitter or drainlayer $4500 each year, yes four and a half thousand dollars every twelve months for each licence... just to go to work, we are qualified, but can't work with out a licence.
You can't choose who you are.....but you are the sum of your choices.......

hi guys/Badger, that is a good idea using this forum to spread the word about the Board to individuals who use this site to get advice, they obviously do not understand what hoops/hurdles we tradespeople have to go through/jump, and the cost just to be able to carry out our skills that we have trained in for many years just to be told that we are not competent to work unless we attend expensive up-skilling courses so as to be able to buy a (very expensive) licence to work, cheers

Mate, every one who contacts us for free advice(which I don't mind giving) should know why we charge what we do and what crap we must go through.....just to go to work to feed our families, if the public knew all this they would last about a week.

thanks to all of you for the replies although contradictory in nature - yes change all pipes or no because the galvanised ones wont be affected?

It is great that we can get advice from members of this board but the reason we need to is that there are some unscrupulous tradies who charge the earth to not do the project properly and I've been stung before and even as seen in the replies i have from the forum you lot cant agree .  As members of the public we now need to get information to arm ourselves against tradies who don't do the job right and won't fix it when it is wrong.  Hence i understand the need for industry registration and upskilling but agree that the cost of doing your job is a killer.  I myself have a qualification and to use it have to do 200 hours upskilling a year and pay for it along with a licence in an area which the government can make changes that severely affect our income.  It is hard on a family to find the extra upskilling hours and the money while still trying to keep a job.  Good on you for complaining and letting us all know about the cost but unfortunately the "regulators"  will just keep doing what they want  so I feel we have the choice to get in and be a voice of change in the system that delivers the education so that it meets your needs and not the bodies need or just get on with it because tomorrow you might not be around.

I understand what you are saying Bakeit - but it is hard to give advice on a forum like this without seeing the job.  If there was a forum for doctors and I put some symptoms up, I'd bet that I'd get plenty of different opinions about what was wrong with me - there is nothing like seeing a problem to help diagnose it.

The best advice I can give when choosing a tradie is to ask around amongst your mates and see who they have used and if they were happy, to check that if it is a trade that is regulated (e.g. plumber, gasfitter, drainlayer, electrician) then check they have a current licence, and that they have insurance cover.  Check up on any of the consumer websites that are available and see what feedback there has been, but meet with them and also get a quote which clearly shows what is and what is not included.  If you do this then you should not have any problems.  Also be aware that cheapest will not always be best.  You get what you pay for, and you pay for what you get.  Most tradies want a customer for life, they want to be your plumber, gasfitter or drainlayer of choice, they want you to use them again, and they also want you to tell all your mates what a good job they did - the unscrupulous ones often are not licensed, or qualified but just advertise as such. 

Have you learned lessons only of those who admired you, and were tender with you, and stood aside for you?  Have you not learned great lessons from those who braced themselves against you, and disputed the passage with you?  (Walt Whitman 1819-1891)  American Poet
