Installing a Gas Pipe Line is much more involved than installing a Water Pipe Line. Gas in Adelaide works on a relatively low pressure compared to that of water even though our main gas infrastructure pipes in Adelaide have done and are still continuing to be upgraded. When you consider that the average pressure of someones water lines to there home is approximately 500kpa on average and the average gas pressures to someones home is approximately 1.4kpa there is a huge differential and this is why it is more complex to design and install a new gas line.
When we as "licensed gas fitters" are looking to install a new gas line there are a few things to take into consideration: How many appliances are we going to be connecting onto? How much gas do these appliances consume and the location of the gas pipe work to be installed. Once these items have all been identified and answered the gas line can then be installed.
So firstly the size of the gas line. As you may have noticed around majority of South Australian homes that the water pipe lines are usually 20mm from the water meter to the house and then most of the time 15mm copper tube is then installed to the various fixtures such as WC's, Wash Basins, Showers, Bidets, Kitchen Sinks and Garden Taps to name a few. With Gas though because we just simply do not have enough pressure around the home from the gas meter you may very well notice that the pipe leading into the house from the meter is actually around 25mm to 40mm in diameter, this is due to the fact that we don't have high pressure into the house so we are therefore relying upon flow through larger diameter pipes.
The layout and amount of the appliances on site will depend on how far a large diameter pipe must travel, for example if a customer has a Gas Continuous Flow Hot Water Service installed towards the back of there home then a large diameter pipe must then be installed all the way to this appliance as a Hot Water Service such as this requires a large amount of gas as it is very thirsty for energy and can consume somewhere in the range of 150 mega joules. Keeping this in mind you also must take into account other items along the way to the Hot Water Service which may need connecting up such as a Gas Cook Top (38 mega joules), portable room heaters (18 mega joules) and Gas Ovens (50 mega joules) these all contribute to the overall size of the gas main as the pipe must have enough flow to supply these appliances as well as the Hot Water System at the end of the line. If the pipe line is too small when all the appliances are in operation they will be starved for gas and not operate to there maximum efficiency.
The materials which are most commonly used are either copper tube or galv pipe work. Majority of plumbers use copper tube as they are geared up to use this because it can not only be used for gas but also water so they are always carrying the various tools needed to install this system such as oxygen and acetylene and Viega crimping equipment. When supporting the new gas pipe line distances to the centres for brackets vary from 1.5m for smaller diameter pipes to then 2.5m for larger diameter pipe work.
Once a new gas pipe line has been constructed and bracketed to Australian Standards by our licensed gas plumbers at Mayfair Plumbing and Gasfitting it must be labelled correctly identifying that the pipe work is carry gas and then tested using a water manometer to ensure no leaks have occurred during the installation process. Once this has been done the various appliances must be commissioned and in most circumstances this is done by using a digital gas manometer. The digital gas manometer is a far more sensitive piece of equipment compared to that of the water manometer and is therefore the preferred method of setting final working pressures of gas appliances such as ovens, cook tops and barbecue's which have regulators that can be manually adjusted. Items such as continuous flow hot water systems and portable gas room heaters adjust there working pressures electronically and there fore do not require adjustment but do require checking with a digital manometer to confirm that they are working to the manufacturers specifications.
Performing the task of sizing a new gas main and then installing it can be daunting for many plumbers and they choose not to get involved with this particular part of plumbing, but with over 20 years of experience on various types of gas installations both domestic and commercial we like to think that our gas plumbers are experts at getting the job done in a professional manner for our customers every time and under budget.

It's been quite an interesting week in Adelaide for me as we head into winter, the phone has been ringing steadily with people inquiring about Hot Water Repairs and Installations Adelaide. Being the Hot Water Wizards we are always busy with Bosch Hot Water Services whether it be a new install or a repair on an existing Bosch Hot Water Service through warranty or just a service call, we do it all when it comes to Hot Water in Adelaide.
In this week's post I'm going to talk about the BOSCH 18e Natural Gas External Hot Water Service. I often get phone calls from my customers who have a BOSCH 18e Hot Water System and they tell me that the unit has stopped working or is leaking water, this is due to the fact that these units are all now at least 10 years old and coming to the end of their working lives. In most cases these are now being upgraded to a newer model called the BOSCH 17e, but that is not always the case as I'm going to explain this week.
A customer in Norwood, Adelaide, South Australia recently contacted with me because we are the "Hot Water Wizards of Adelaide" and wanted some advice on repairing his Bosch 18e, the unit was displaying an error code 14 on his temperature control pad inside the home, which indicates a faulty internal wrap around fuse, this device detects over temperature and causes the Hot Water unit to shut down to protect itself from catastrophic failure. This fuse is located at high level inside the Hot Water Service casing and wraps around the copper heat ex changer. It is approx 3mm in diameter and approximately 1m in length and gets wrapped around the heat ex changer 2 times, it is held in place by a series of stainless steel clips and is then plugged into its relevant terminal connections to communicate with the PCB.
When it comes to replacing a part such as this on a Hot Water Service of this age the most cost effective method of resolving this problem is to supply and install a new hot water service. The reasoning behind this is due to the labour which is involved with actually being able to remove the old fuse and then install a new one. In order to get to the fuse nearly every component of the BOSCH 18e needs to be carefully removed and if you have ever looked inside one of these units it's a mine field to say the least. My customer in this instance insisted on ordering the new part and repairing the existing Hot Water Service, so I did. Once the part arrived from BOSCH I made a time to attend my customer's house and start the repairs. The first components to come out of the unit are related to the gas burner and fan and are relatively easy to remove, it wasn't until I started on the sections of the Hot Water unit which relate to water section that trouble started appearing, corrosion had set in and it started making the removal of further components near on impossible, after much persistence I had to pull up stumps and tell the customer the bad news.
Unfortunately after much perseverance and patience the old BOSCH 18e could not be salvaged, my customer was very understanding and agreed that the only way forward was to get a new BOSCH 17e. As I previously mentioned there was a control pad already installed onsite, this is no longer compatible with the new units and therefore also needs replacing if the customer wants to have a control pad in the future, the wiring is compatible just not the control pad. Swapping over the old control pad with the new is probably the easiest part of the project as the fixing holes line up and the wiring is very simple for a licensed plumber/gasfitter Adelaide.
When it comes to installing the pipe work the configuration (when your standing in front of the unit looking at it) as far as hot on far left and gas on far right with cold in the middle is still the same, but the distances off the back mounting wall have slightly differed, so some adjustments will be needed when it comes to pipe work installation. The mounting holes are now also at slightly wider (centres) so new fixing holes will also be required, all pretty standard stuff when we talk about installing a new Hot Water Service Adelaide.
Once all the pipe work and control pad has been installed and tested including working pressures of the gas on the BOSCH 17e its time to enjoy your HOT WATER! With the new control pad installed my customer can now dial up the desired temperature of their shower or kitchen sink to do the dishes AND as a huge bonus the control pad can also be programmed to completely fill a bath to the desired height with warm water, amazing technology!
Finishing off this chilly week in #Adelaide if you do find yourself in need of some kind of Hot Water Repair please remember our licensed gas plumbers from Mayfair Plumbing and Gasfitting and visit us on the web at: http://www.yelp.com.au/biz/mayfair-plumbing-and-gasfitting-adelaide-3 or call Aaron on 0429 361 819 and discuss your next Hot Water project whether it be gas, electric, heat pump, lpg or solar we can help you.
How many times do I go to a customers house or business in Adelaide as a Class A Licensed Gasfitter with over 20 years of experience and find that some weekend warrior or home handy man has been tinkering with the Gas Pipe Lines, Oh My God! This is totally unacceptable and against the law - STOP IT you are putting lives in danger, if you are not licensed to work with gas then stop touching it NOW!!!! Its only a matter of time until someone or something is blown up and lives are taken through these un licensed people performing these tasks.
Some of the more recent examples I have come across are the following:
In closing this week I think my message has been clear, there is a very good reason why us Gas Plumbers are continually up skilling and have also done a lengthy amount of study to work with gas. People are either not understanding what danger they are putting themselves and others in or simply do not care, BUT which ever it is they need to stop cutting corners it will always catch up with you in life and if it is at the expense of another's life there is no worst outcome, so next time you are thinking anything GAS related in Adelaide call Aaron from Mayfair Plumbing and Gasfitting on 0429 361 819 or visit us at http://www.crunchbase.com/organization/mayfair-plumbing-and-gasfitting I hope you have enjoyed my latest BLOG about being safe with GAS its serious stuff and not to be messed with unless your a licensed Gasfitter Adelaide.
Introducing an AMAZING piece of Plumbing technology that's revolutionised the Plumbing Industry in Adelaide
Introducing an amazing piece of new technology to the Plumbing and Gas industry in Adelaide. There are a lot of Plumbing Companies which still use the traditional Oxy and Acetylene gas and torches to solder copper and brass pipes together and in some circumstances we still use this method at Mayfair Plumbing and Gasfitting when soldering a piece of copper tube, but in "Emergency Plumbing Adelaide" the VIEGA tool is king!
BUT in this weeks blog installment I'm going to talk to you about some AMAZING changes to way we as plumbers join copper and brass pipes together, its called "Crimping" or "Pressing" of copper and brass fittings. At Mayfair Plumbing we use a tool made by a manufacturer called VIEGA, there are now multiple other companies on the market today who also manufacture these tools such as Ridgid, Rothenberger and Kempress. The fortunate thing about these different manufacturers being on the market is that all of the copper and brass fittings for these machines are compatible with each other. In my short you tube video below I have filmed what the VIEGA Pressgun 4B looks like in action when it crimps a 15mm or 1/2" diameter water copper elbow and also some of the more common VIEGA and B Press fittings which we use day to day in our plumbing duties around South Australia.
So as you can see from this amazing video filmed right here in #Adelaide technology has really come a long way as far as the installation and repairs of copper and brass fittings especially in a Plumbing Emergency. As I mentioned in the you tube video these plumbing parts come in all different sizes varying from 1/2" all the way up to 4" in diameter and we at Mayfair Plumbing have the equipment and parts to cover you for all the varying sizes you might need installed.
One of the huge bonuses of the Pro Press and Crimping Technology is that a joint can be put together while there is still water in the pipe making this ideal in Plumbing Emergencies Adelaide if a customer hits there water main while doing a spot of gardening we can quickly attend, expose the copper pipe and slide a VIEGA joiner piece in and quickly crimp the fitting with a our Pressgun 4B. A typical task such as this would involve far more work if it were to be welded using an Oxy and Acetylene Torch and also the chance of a leak is much greater mainly due to the fact that the copper pipe in the ground is more than likely going to be dirty and full of water making it hard to solder up.
We believe that by using this AMAZING piece of new plumbing technology not only does it make helping our customers much easier but it is also saving our customers huge amounts of money as the labour time involved for a copper or brass joint to be performed is far less therefore we are on site for a smaller amount of time costing our customers a lot less in labour charges.
