Corbin, Thanks for the info, it is very interesting. I will reread it several more times later. Here in Texas, and most of the US, 3/4 inch is the minimum pipe size for a residential service. A 1/2 inch pipe can supply only a maximum of three plumbing fixtures inside a house. And 1/4 inch can only be used for the very short distance between a cut-off valve below a sink up to its faucet. Even our cheap garden hoses are 3/8 to 1/2 inch. A good rubber hose is 3/4 inch.These things make me wonder if 1/4 inch in Canada is the same as 1/4 inch in the US. And I wonder if those houses you spoke of had very minimum in the way of plumbing fixtures. I wouldnt think they could have two or more bathrooms as is the norm here. Thanks again for the reply. Don
