Re: Plumbing inspection failed 8Mar 28, 2014 7:55 pm Check valve, one way valve, all the same. http://www.duralirrigation.com.au/Categ ... alves.html Back flow prevention regulations are to prevent a device from syphoning contaminated water into the mains water supply should the mains water be down and there is negative mains pressure. For a hand held shower rose, the prime example is for its length to not be long enough to somehow drop into a toilet or basin (or put there by a child) but if the shower base drain is blocked or back flows, it can also retain contaminated water. 3in1 Supadiverta.

Re: Plumbing inspection failed 9Mar 29, 2014 7:58 am Thanks for that explanation SaveH20. That's really interesting. In Snandan's case I think I would be asking Tradelink how much such a valve would cost and asking the builder if they can supply it themselves, or just changing shower roses as you say. Snandan certainly needs to know how much the valve will cost before agreeing to it. Do some shower roses have such a valve built in? Or is it always supplied by the plumber at the time of installation? And where does it go? Inside the shower wall? Re: Plumbing inspection failed 11Mar 29, 2014 8:47 am Just a few more questions if anyone knows the answers. In our municipality it seems we have backflow prevention at the meter (see below): https://www.citywestwater.com.au/docume ... dition.pdf (I notice that once again the onus seems to be on the homeowner!!) Does this mean you don't need it for individual fittings? Does Queensland do the opposite?

And where does it go? Inside the shower wall? The valve is usually fitted to the hose but the last thing a person would want is to have the builder raise a variation and have the plumber rip some tiles off to fit a valve to the pipe work. I would be extremely surprised if you couldn't simply buy and fit a shorter optional hose for the model depicted. Knocking it back because it reaches the shower floor is picky (although technically correct) but if the shower was over a bath, it would be justified. Things can get damaged if they are dropped and it isn't good to have the hose long enough to reach the floor in any case. The plumber probably hasn't fitted the connecting pipes high enough. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

Yes, this has already happened. The neck that holds the shower rose up started to droop within weeks of taking possession of the house and when it finally broke the shower rose hit the shower base and has gouged it. So Snandan you are better off with a shower rose that doesn't lie on the floor. Re: Plumbing inspection failed 14Mar 29, 2014 9:16 am Just thinkng about what SaveH20 said about the height of the pipes, the following picture shows how our shower is attached to the wall:
Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ So it looks like the pipes are set fairly low and the problem could have been prevented. Snandan - you may want to see how your shower rose was fitted to the wall.

Does this mean you don't need it for individual fittings? Does Queensland do the opposite? Back flow prevention is covered in AS/NZS 3500.1:2003 Section 4. You will be aware that when plumbers connect water tank pumps to the house mains water pipe, check valves have to be fitted to prevent the possibility of back flow contamination to the mains water supply. Some utility operators also fit back flow devices at the meter due to the increased popularity of water tanks in suburbia. EDIT 30/07/2014 The most serious situation would arise if there was sewage backflow into the shower base. This could, for example, happen during localised flooding if other plumbing safeguards were faulty. Sorry to hear about your shower base and the shower rose.

When I tell you that I woke at 4am this morning having nightmares about our plumbing -( I can't get it out of my head that there is some pipe somewhere leaking into the foundations) - you won't be surprised. Re: Plumbing inspection failed 17Mar 29, 2014 11:50 am I'm worried too!! Last night I dreamt that I was eating a huge marshmallow but when I woke up...my pillow was gone. 3in1 Supadiverta.

Re: Plumbing inspection failed 19Mar 29, 2014 5:25 pm Great to see some great questions from everyone. We did go to Tradelink and the guy there was surprised to hear what we told him. He said he has not seen any issues with the Flexispray we fitting in unless the plumber has fitted the unit too low or if it was fitted on top of a bath then and only then would it create an issue. We also asked about the valve and what it would costs to get them. The one he showed us was about $15 - $20. So would be less than $50 for the 2 we need fitted. We had another look at the hose in the shower; it does not lay on floor unless you physically put it on the shower floor. The other thing is that the shower is not on top of a bath so not sure what it will back flow unless the shower drainage is totally blocked which will mean the house will start to get flooded it.. I am very worried that they trying to cover their costs by charging us; knowing that we are a week away from handover. I had a look online about this so called valve they have talked about and yes, there are some fittings that come with it where it is necessary. I have no clue who did the inspection as I have not received any report; I will be asking for it before signing off on anything. I wish I do win lottery....LOL Re: Plumbing inspection failed 20Mar 29, 2014 6:55 pm We'll be all ears to hear the details snandan. Good luck with handover.
