Re: Capped water point unusual cost ($5000) 17Aug 27, 2021 5:54 pm So our builder is insisting in installing an RPZD from the water mains (and supplying to the WHOLE house) if we are to get capped water points in the each of the 3 toilet for future Bidet/Douche seat installation. Doesn't the RPZD 'supplying to the WHOLE house' from the mains beats the purpose of the requirement of the RPZD valve? My limited understanding is that the valve is required to prevent any backflow of contaminated water from the bidet into the mains and water lines to rest of the house. So in case f there is a pressure drop on the mains supply, the RPZD valve will stop any backflow of contaminated water into the pipes. But if the RPZD valve is supplying to the WHOLE house, then if there's a pressure drop on the mains supply, there is the RISK that contaminated water from the bidet may backflow into on of the taps around the house when its turned on. So question is should the Capped Water points in toilet (for future Bidet/Douche) installation be connect through a separate pipe line from the mains with the RPZD valve? Or RPZD valve connected at the mains and supplying ALL water points in the house including the capped water points in the toilets....? Any clarifications from experts (or those who have an understanding of RPZD valves) would be appreciated. Thanks in advance Re: Capped water point unusual cost ($5000) 18Aug 27, 2021 6:05 pm I didn't proceed with the proposal from builder as it seemed unreasonable the dumbest part was builder had their own line of toilet suite with built in automatic bidet seats that did not require any such rpzd value solution. It's just that they quoted premium price for the upgrade from standard. When I asked why their own would not require rpzd value, they said its because they are doing the installation and all points will be terminated at the connection point for the suite. I did arrange for a garden tap just outside the exterier wall of where master room toilet is so when I decide I want to upgrade I can ask plumber's help to do a pass through point from there. good luck. Re: Capped water point unusual cost ($5000) 19Aug 27, 2021 6:22 pm Gees...WOW at some of the tricks these builders try to play. Good on you for rejecting their ridiculous 'solution'. That is some great out of the box thinking in getting an external garden tap opposite the ensuite toilet! Lucky your house layout was such that this was possible. Not so lucky for me as two of the toilets are behind internal walls. Cheers Re: Capped water point unusual cost ($5000) 20Aug 29, 2021 10:44 am Any Bidet or hand held shower hose in baths should have RPZ valves fitted by law to comply. The bidet shop dont always tell you all the info as they want to sell products but if you check with plumber or regulations yourself you will find you are obligated to install the valve. The water company that feeds your home will also need to be notified as if there are any issues with the mains and you dont comply it can be hefty fines. The valves can be retrofitted either beside the toilet or on the external wall outside the toilet if applicable so it protects the rest of the house as nobody wants particles coming out of their kitchen taps. If the nozzle of the bidet spray goes below the top rim of toilet bowl than cross contamination will occur, hence the need for these valves. You can put one on the mains at the front but that is only protecting the mains and your neighbours its not protecting your house. The are strict rules n regs on bidets for a very good reason to stop cross contamination in the home Hi all, Our boundary perimeter fences need replacing (3 sides).
