Fellow Practitioners Update / Fellow Practitioner Issue 385 Dated 8 November 2019
« Last post by Wal on November 08, 2019, 06:31:52 AM »
This week we start looking at the regulatory governance (what the Plumbers Gasfitters and Drainlayers Board and Government do) and where does industry representation come from. Is there a chance anticompetitive behaviour is being supported by legislation?

Ask Plumbers (Public) / Re: Silicone around a cistern?
« Last post by Plumber on October 22, 2019, 11:34:17 PM »
Will it do the job? probably. Is this the proper method ? probably not as most toilets have the ability (Two holes back of cistern) to mount up against the wall (check the toilet manual) assuming the walls are straight. So really, its circumstantial and the plumber will typically decide what method is best used to achieve a workable outcome.

BTW toilets are notoriously known to require extremely straight floors and walls to fit, look and function correctly. Often they need to be wedged up off the floor to accomplish a flush fit up against the wall to enable correct mounting but this could result in the pan "wobbling" over time if not done correctly.

Its not uncommon to run a bead of silicon along the cistern top (one horizontal line between cistern and wall)  before the lid goes on. This adds additional strength and maintains hygiene behind cistern. Also it can also be easily cut if the toilet ever needs to be removed. 

So, if the plumber used silicone he was either experienced or lazy. That is something you will need to evaluate based on your installation environment, toilet type etc. I hope this helps.

Ask Plumbers (Public) / Silicone around a cistern?
« Last post by Lisaeh on October 18, 2019, 11:45:00 AM »
We recently had a back to wall toilet installed.  We noticed the toilet rocked and asked plumber to return.  He said it was the seat but when we told him we thought it was the cistern, he siliconed around the cistern on the wall?  Is this a normal procedure to fix this problem?

Q & A - Hot Water Cylinders / Re: HWC and Valve questions
« Last post by blitzn on October 16, 2019, 06:32:46 PM »
Hi, Thanks for the prompt reply on this. Will leave the system as is for now. Currently hunting around to go mains pressure as you said. Think this will be the best option over all. Cheers

Q & A - Hot Water Cylinders / Re: HWC and Valve questions

Hi Alan,

Obviously any recommendation and information provided cannot be taken as an absolute and will depend on various onsite conditions and knowledge which are not available to me. As such, before you endeavour to be "hands on" please get a registered plumber to have a look and confirm, even carry out any plumbing changes.

To answer your questions:

1) No, if you add 7.6 and the relief valve is rated below this it will start leaking (relieving pressure). You need someone to calculate total possible pressure in the system VS total achievable pressure and both valves (incoming and relief) need to match. Where the fixtures are within that available head also plays a role.

2) No, As per #1 you risk the overflow running or even exceeding the total system pressure which worse case scenario will result in your hot water cylinder bursting.

3) relief valves are not installed at the road, you may have this wrong and may be referring to the limiting valve? In any case this reinforces that you should  get someone to look at your conditions and provide professional advice.

Another thing you may want to consider if you are looking for higher pressure is to simply replace the cylinder with a mains pressure tank. They are as cheap as 1900 installed these days. Any money you spend on valves etc could be going towards a new system.

I hope this helps.

Q & A - Hot Water Cylinders / HWC and Valve questions
« Last post by blitzn on October 15, 2019, 06:30:37 PM »
Hi All

I have a 135ltr 7.6mtr head, low pressure Reeem hot water cylinder in my house. I currently have a 3.6 KPA nefa pressure regulating valve under the house? I have a 4 mtr high (from the floor) copper line running out through the roof with a pressure relief valve attached. there are no markings or stickers on the pressure relief valve and is 15 years old im assuming it is a 3.6kpa one? This is not dripping or leaking water.  I have attached a pressure gauge to my hot water line and it is only reading 4psi with outlets off (28kpa)

Questions are...

1 should i have a 7.6kpa Pressure Regulating Valve to match for this cylinder?
2 If i should have a 7.6kpa valve can i increase the 3.6kpa nefa valve to around 8-9psi (62kpa to be safe) on the hotwater side? 
3 is it worth me replacing my relief valve on the rood to ensure it is a 3.6kpa valve?

Any help here would be appreciated
Cheers
Alan
