The house (and Stef) have taken and passed their first test: checking that the plumbing doesn't leak. We got an A+! Well, they don't actually give you a grade, but everything checked out so I'm going to give them an honorary gold star.
Stef has put in all the pipes himself: black pipes to get the water up from the hole in the ground, and blue ones to carry cold water, and red ones for hot from the not-yet-installed hot water tanks (really, they're actually colour coded, which is one of those very-clever-and-very-simple ideas that someone should get a prize for). Oh, actually Stef tells me we actually have quite a few red pipes carrying cold water because Rona had a sale on red pipe... ha!
To test it, they stick some sort of valve at the bottom and then fill the whole house of pipes up with water, then let it sit for a few hours and check for leaks. Simple. Apparently the first junction that Stef tested did, in fact, have a leak... but he says it's a bit he was planning on re-doing anyway (I don't know why... I'm not privy to all the details). This made him somewhat, well, anxious. But the rest went well and, as I say, he passed with flying colours.
So now the rest of the house gets inspected, and then someone will come and spray the walls full of insulation. We're really getting somewhere now!
