Ok...there is an existing drainage pipe on the south side. It is easy to calculate this pipe's maximum compliant flow rate and this is the first thing that needs to be established. The use of a pumped wet well, even if the water is pumped to an existing drain rather than pumped to the street as I pr...

You have not mentioned the roof area, the slope of the land, information the plumber has given you about pump and pit sizes and costs amongst other things. Too many unknowns to give a proper answer but here are a few things to consider. What you describe is a pumped wet well stormwater detention sys...

Pretty much sums it up. A big influence on drainage is the pop, rectangular pops are much narrower and have a greater percentage decrease in width at their narrowest point than round pops have. This not only effects the initial flow (fall) characteristic, it also means that rectangular pops are less...

If you have existing paving and cant install any more downpipes it may pay you to use guttering with a slotted front (cant recall the name) which will alleviate eaves flooding in a torrential downpour like you seem to be regularly having in Sydney. If the gutters flood back into the eaves, the fixt...

Added more down pipes on a large house doesn't always help given that the bottle neck can sometimes be the one 90mm pipe that carries water from all downpipes to outside the property. 90 mm pipe is not pressure or DWV rated and should never be used to "carries water from all downpipes to outsi...

Half round gutters have superior flow and self cleaning characteristics but they need to suit the style of the house. Flow is governed by the fall and distance between downpipes. Huge numbers of new homes are passed every year with non compliant guttering.

That's actually not true. You can do it simply by not paying the bill, they cut you off and put a lock on the meter. The OP is in Melbourne and if you have mains water passing the property, you get billed service charges regardless of whether you use the water or not. If you don't pay the account o...

'Plastic' pipe is rated for 95 degrees. Re chafing, a lot of plumbers are as rough as guts but the requirement for full insulation on hot water pipes, regardless of the material type of pipe, would give additional protection. 'Plastic' pipe also absorbs shock waves (hammer) to a large degree. If usi...
