Bung: What year would they have been put in and what sort of seal did the pipes have?
Our 1946 vintage pipes were cemented (badly) and the sewage side has almost completely been replaced with PVC. You should get your drainlayer to video both of your pipe runs.
Fred99: OK - here's a DIY project gone bad, as happens from time to time.
EQ damaged concrete paths removed (about 60M2) and dumped. I get to this corner, lift the slab I've broken, and here's the stormwater pipe exposed, and as I lifted it the concrete above, the elbow and pipe to the right fell apart and into a hole which had been scoured out by probably a separate EQ related drainage issue (which has been addressed), but possibly exacerbated by the stormwater drain itself leaking. I've propped the drain back into position - as in the photo, as the hole underneath is about 500mm deep in parts. I managed to force the seals back into position, ran water down the pipe for a couple of hours, and there's no sign of leakage, so it's probably better than it was. My drainlayer can't come up for a week or so. We'll video the entire stormwater system, and possibly need to excavate and replace the lot. All I wanted to do was to replace cracked concrete paths.
DarthKermit: That big 6.2 earthquake on 20 January got me all shook up and determined to do something about the old brick chimney in the middle of our house.
It's a 1950's non-reinforced structure built in the middle of the house between the hallway and the lounge. If it fell, it would do a lot of damage to our house no matter which direction it toppled.
I took the top off it this morning, down as close to the roof as I could. Next weekend (weather permitting), I want to remove several more layers to get it below roof level. Then I can put the 2nd hand concrete roof tiles I have in the gap left by the chimney.
Once this tricky part is done I can reduce its height (inside the attic) layer by layer as time permits.
When it's all gone, there will be a nice big space between our existing HW cupboard and linen cupboard that can be turned into another cupboard.
Bung: Do CCC have a random rule generator? It is expected that home owners are always surprised but how is it that your professionals working in that area weren't aware?
