Marking out the Drainage Trenches
The plumber and I marking out the trenches.

More Trenches!!!
By this stage we were sick of continually going down. More excavation and more hammering through rock.

The first Pipes
These are all very boring pictures of the drainage going in. It was all very exciting at the time but looking back we wondered why we took so many. While they would be good reference material we hope we never have to use them.
-
The white pipes are the sewerage and the green are the stormwater. While we don't have a tank in yet we may put one in later so have directed the stormwater into a gravel pit temporarily. This way we can add the tank in when we have the money : )
-
Once the drainage was all in we went through and double checked all the measurements. It was lucky that we did as the toilet in the bathroom would have ended up being in the bath??? There were some other interesting anomalies with the plan. We had a few words to say to the plumber!!!

Always double check everything. Even though you aren't the "expert" you have to live with the results. Don't assume that your 'tradesmen' are actually tradesmen! Most of them just don't take the time to check their work.
Tips and Tricks
- Check all the plumbing measurements. Once the slab is down, making corrections is VERY difficult and very costly. While this seems an obvious suggestion, if you are paying a plumber as we were, you tend to expect that they can measure better than you. Mmm, not necessarily. As you might imagine we now have employed a new plumber : )
- We have had to use offset collars to align the toilets correctly as the concreter didn't align the set downs in the wet area correctly during the pour. All of the toilets were a little off centre. The collars are about $15 each and are available from a trade plumbing outlet. We managed to find an offset collar that was 65mm that allowed us to correct the most incorrectly offset toilet. Most of this was caused by slack measuring by the infamous carpenters. A picture of the collar can be found on the plumbing page.
