The tenants also say in heavy rain one of the downpipe holes overflows. A contractor has said a soakwell has probably collapsed and they want to dig up the paving an put a polypropylene one in. This costs an extra $1500 and they won't redo the paving afterwards so I am not that keen. I am also doub...

Thank you for the added information and for adding the downpipes to the photo. I'll give a summary before I give course of action recommendations. Roof drainage regulations Victoria has a variation in the National Construction Code (NCC) that only permits roof drainage to be installed to the Austral...

I need the answer to a few questions before I can give some advice. I have a 30 y/o single story brick and tile house in Perth currently rented out. The gutters (~80 lineal meters) are corroded and need to be replaced. The tenants also say in heavy rain one of the downpipe holes overflows. https://f...

You don't have a warranty? What country are you in?

The downpipe just around the cormer is weird as it is connected to another downpipe by plumbing that downpipe across the wall and around the corner. The downpipe around the corner then goes underground to one would assume the vertical riser but maybe it connects to the storm water and the vertical r...

You have changed the numbers on a couple of the pipes. Just dig at the base of the 3 pipes near the corner to see where they connect. I also see that the pipes dump a concentrated flow of water above the submersible pump. Not good!

Pipe 1 is a vertical riser. A vertical riser rises from a subsurface pipe that is supplied by one or more remote downpipes. You have a downpipe just around the corner that is fitted with a cap (flush outlet) close to the ground. This downpipe should have being plumbed directly to the tank's meshed ...

Waiting.....:-? https://forum.homeone.com.au/u/38282_1704931099.jpg Information asked for is required before a full answer can be given. There are also other design issues that the owner is most probably not aware of.

Thanks for the photos. Your first two photos show a 'dry' system pipe that discharges into the meshed basket at the top of the tank. This downpipe should not be overflowing. You have said that two downpipes overflow from the top of the downpipes but the downpipes sit underneath leaf diverters. Do th...

We built a house with burbank in Melbourne. Initially it was connected incorrectly with the overflowing from the tank connected to the inlet pipe. Just when you think you have heard of everything.....:roll: Unfortunately, plumbers have no formal training in rainwater harvesting and numerous bad ins...

They look very close to your house, maybe check the roots are not going to cause problems with the house foundations or plumbing Plus having leaves block the gutter.

Good luck with it. I don't know what the cost of a nice bidet seat with a 25mm air gap will be but you are obviously deducting the cost of a RPZ valve and its installation from the seat's cost. The additional cost savings of the annual RPZ test will also be substantial.

I can't recommend anything, sorry, because I have nothing to do with bidets apart from advising people I talk to that their bidet isn't compliant when I see they have rainwater connected. Most of the time, those installations are also DIY and don't have a RPZ or even a DC at times. There are special...

A RPZ valve is larger than a standard DC valve due to it having the backflow discharge facility. A RPZ valve is also mandated to have annual inspections. Maybe you could be inventive by having a recessed wall storage space (or two for aesthetics) that could be pulled out when required to check the R...

Bunnings informed this would do the job https://www.bunnings.com.au/kinetic-chrome-backflow-preventer_p4920512 You are apparently intending to do ILLEGAL DIY plumbing work ! Here are the facts: What you are (apparently) intending to (wrongly and illegally) do is regulated plumbing work that must be...

Your licensed plumber will know the regulations and what to do.
