We live on a 300' by 300' lot. We just had another baby, and are needing to add on. Once completed, we would have 3 toilets, 2 tubs, 1 walk-in shower, 1 tub/shower combo, 7 sinks, dishwasher, and washing machine. I also plan to add 2 bury hydrants, and 2 sillcocks. Some day we hope to add a garage with a full bath in it as well.
Since the addition will go over where the current main line is, I was thinking I should replace the old galvanized main line now. I thought I would put the portion that would be under the addition inside a PVC sleeve so it could easily be replaced if there were ever issues.
Because of the big demands from the exterior hydrants (probably would have multiples running at once) and the possibility of adding another bathroom later, I was thinking about using 1-1/4" Type A Pex for the main line (about 100'). I'd branch off of that with 3/4" Type A Pex (about 200' total) to each bury hydrant. I'd either continue the 1-1/4" into the house, or go down to 1" after the bury hydrants. If I have enough I'd rather do the 1-1/4" into the house since that will service the sillcocks, but there are a couple of possible issues. We'd like to add a patio some day to the area where the pipe goes into the house, so I may do a sleeve under that area, as well. If that's the case, I'd need to do a 90 degree turn, instead of coming in on a curve. Which would mean 100' of pipe may not quite be enough. I hope to do all of this work myself, but plan to have a plumber do the tie-ins at the water meter and the house.
If you've made it this far in my post, then thanks! These always turn out longer than I want them to...
Does my plan seem reasonable? Is 1-1/4" overkill? There is a big jump in price from 1" Type A to 1-1/4" Type A, but I don't want to be lacking pressure inside if the outside hydrants are running. On the hydrants - would they have plenty of water if I had one 3/4" line that tee'd off into two 3/4" lines after 50' or so, then went another 50'-75' to each hydrant after the tee? I'm not 100% sure how to do the lines for the sillcocks, but I can cross that bridge after I've got the main line tackled.
