Browse Forums Building Standards; Getting It Right! 1 May 13, 2009 11:19 am Hi everyone. This is a copy of a post I placed in the 'Building a new home' topics. No one said boo, so I'm hoping this forum might be better placed.. We're seeking some advice about the correct way to connect silt pits. On our new home, one of the silt pits has not been located according to the engineering plans and also, in the plans, the two silt pits are supposed to have a discrete separate pipe & trench running around the house conecting the two silt pits as well as them just joining up with the same pipe as the downpipes. Follow? In other words there's two silt pits at diaganolly opposite corners of the house (in the plans). They both join up to the immeditae pipe that connects to all the down pipes running along side the house. But in the plans (and I have seen this in other plans), there is meant to be a separate, discrete trench running accross the front and down to the rear silt pit as well. The plumbers don't want to come back, insisting that the silt pits have been connected up to the down-pipe pipes (under the gound - then off to LPOD supposedly), and that is all that isnecessry. They claim that the extra trench & pipe is not neccesary. Does anyone know about this kind of thing? Our soil report says our site should be well drained. Is there a reason for this separate pipe? Should we insist they build it? Does it matter? A guy at the Plumbing Commission reckons the engineers "just put it in to make things harder than it needs to be". I was obviously not satisfied with this explaination. If engineers have drawn it, what is it's purpose? As I mentioned, I have seen this separate trench drawn in other plans from a different builder so, I can only assume it has a purpose. We'd be grateful for any opinions. Thankyou. Cheers Re: Silt pit advice 2Sep 20, 2014 12:30 am Hi bnik, Looks as though you have been overlooked. I don't exactly follow, but write to the engineer and accurately draw what has been installed and find out from him or another engineer what was required I suggest. The idea is to maintain a fairly uniform moisture level in the soil deep down I believe. If the drainage is less than contracted you are entitled to a deduction it seems. You're still under warranty for 6.5 years you know. Good luck.

The OP was asking about silt pits. The silt pit plumbing as described is fine, a pipe connecting the two is unnecessary and not a good idea in any case as it could accumulate bed load. 3in1 Supadiverta.
