Thread: Rainwater tank and plumbing DYI?

G'Day Brian,

I am in a similar situation.
I ask myself, "May I do some of my own plumbing?"

NO!
I may not
one has to be a registered plumber. As with 240V House Electrical WORK

BUT!
I know that "IF" I were to do so,
it would be much better than some of the work I have seen over the past couple of years.
I also have a Plumber who will check it, and sign off on it

In SA. there is no licence requirement for stormwater, just must comply to council regs. Don't know if it is the same in Vic.

Same here the local council has authority over stormwater installations, you can do the pipework yourself, in and out of the tank, you can replace your downpipes, tank overflow is usually connected back in to the storm water, but check all this with your local council.

Hi All,

I recently started my water tank project (I have poured the slab, and have all the pvc, connectors, etc), today I fitted the leaf beater and next is the piping to the inlet.

I have a question regarding the best practice for the angle of storm water piping to the tank, someone has mentioned a drop of 2%, e.g. 2cm for every 100cm.

Most of the installation pictures i've found on the net show very little slope in the pipes (as you can see they run almost parallel with the brick work). Some examples :

and


but then here is a pic where the pipes are quite angled



Is there a standard, or just as long as the water doesn't stall in the pipes all is okay?.

Thanks,
Aaron

minimum fall is 1:100 for storm water, so 10mm for every metre.

Thanks!

Our new place has stagnant water in the water tank pipes as they go underground before reemerging into the tank above them.

Its plumbed into the non drinking areas.

The builder told me ( NSW), that you can do your own stormwater but not sewer.

Any advice with regard to Victorian plumbing regs. Happy to go through the right channels but would like to have a go at the bits I'm legally allowed to tackle.

You may need a DA for a 23000L tank in a suburban area...

just something to think about.

Sorry, but what is a DA?

In sa you need a builders liscence or ownerbuilders permit to do stormwater, council can not override this unless they issue you with an owner builders permit.

Not sure about the licence but you will not get a rebate without a plumbers certificate (if you care).

Also, DA - development approval.

Seems like plumbing regs are much more relaxed here in QLD. Maybe cause it's the "smart state" hahaha!

bricks, when I contacted the council they said I need no licence no permit they in fact came out and connected the pipe through the footpath at no charge
