I am a new member from vancouver B.C.,I am going to be putting in a new water service from the street to the house. I have decided to use 1 inch hd polyethelene, my question is when it enters the house what fittings do I use from the elbow to where it transitions to 1/2 inch copper. If anybody has photos of the fittings coul you please post them.:huh:

What he said there^^^^^^^^ and why 1/2 inch? I would recommend 3/4 for water Volume

+1..., 1/2" is way too small.

would it make more sense to use 3/4 inch because all the lines inside are 1/2 inch copper?

Ok... Here is how it works... You may not like me after this because if your wife reads it you will be doing more work :)

If you have 1/2 inch pipe in your house... and only 1/2 inch pipe.... Do this test... Go jump in the shower get the water perfect! and then have your wife flush the toilet :censored: Notice the temperature spike? That is because the pipe size on your main run is 1/2 inch... Now have your wife get in and tell her that you know how to fix this problem as you flush the toilet.

Here is the solution
1- Main water line should be 3/4 of an inch. I would walk away from a house that has 1/2 inch.
2- Replace your "Home Runs" this is the main line for the cold and the Hot that run across the house. I had a Home Owner drop the price 4000 because they had 1/2 inch pipe and could not figure out how to fix the temperature fluctuation when showering.

Now How hard is it? To me not hard at all but, you need to make that decision.

Go to where your main comes into the house and follow that line all the way to the water heater. Count the number of connections and write them down.
Now follow the Hot and do the same.
Add 1 Slip Coupling for every Branch that comes off of those main lines
Measure the Length of the cold from main to heater and the Hot from Heater to the last branch add 10% for waste

Now Here is your Material list
(Length of pipe)X 10% rounded up to next 10.... this is your 3/4 pipe
your "t" will be 3/4 by 1/2 T instead of just 1/2 tees
for your last 90 just get a 3/4
Get 1 Stick of 1/2 in pipe (10 ft)
The Slip Couplings will be 1/2 inch
Glue or Solder and flux depending on type of pipe

make the repairs
Cut the pipes that branch off about 6 inches from the main line
Start at valve
Measure and cut the pipe
Install the pipe as you go making sure to dry fit everything
then go back and glue or solder
for the Branches I like to have the pipe precut to move quick...
What I do is cut the 1/2 inch pipe in 8-10 inch pieces... and as I move up the main I mark the small precut piece and my helper cuts and fits the pipe as I do the next part of the main.

Sounds like a lot of work but you need to decide if you think you can do it. In the typical 1 bath house with laundry and 2 hose bibs you will have maybe 12 branches... Again to me it is quick and Easy... but this is also for exposed pipe... if the Pipe is behind drywall etc it is a different story


Wether you decide to do the partial Re-pipe or not USE 3/4 inch for the Main... You will be much happier:thumbsup:
