    Default What type of pipe??????

    I am wanting to install (in my Garage) A pump, pressure tank, and a 500 gal tank for the water to my house. I was wondering what type of pipe I should use to conect all this, copper, steel, or PVC?


    Thanks

    In order...Copper, then CPVC, then PEX.....Does your area ever freeze?

    500 gallons won't go very far...a larger tank would be much better...

    I'm in Texas. We might get 1 or 2 nights that could freeze, but I can insolate the pipes.

    Is your water acidic? If so you should not use pipe that will be affected by the acidic water--like copper.

    For the piping within the garage I would think that standard schedule 40 PVC would be a good choice because it does the job and is less expensive than the alternatives. For the pipe from the garage to the house I would be inclined to use the same pipe if the garage is attached to the house or black PVC that is used in wells if the garage is a free standing structure. Black PVC has a degree of flexibility and is relatively inexpensive and usually easier for underground runs. All of the foregoing assumes that these materials are allowable under your local codes.

    Why not 40? Does it have to be 80?

    CPVC within the structure.

    Is this a code issue? Schedule 40 is widely used in my area (Eastern PA).

    I did a search and found the following information:

    "Code information. Model plumbing codes sponsored by associations of enforcement officials or other industry groups are the basis for most of the more than 14,000 local codes in the United States. Every model plumbing code in the United States approves the use of PVC pipe.

    PVC pipe is permitted to be used in any water service system, without limitation, in the National Plumbing Code (Building Officials and Code Administrators International), Uniform Plumbing Code (International Association of Plumbing and Mechanical Officials), National Standard Plumbing Code (Plumbing-Heating-Cooling Contractors Association) and Standard Plumbing Code (Southern Building Code Congress International). "

    The above quote came from this site:

    Agree.

    I didn't see anything in the original post about hooking up hot water and ASSUMED that the 500 gallon tank referred to was not a hot water tank.

    Are we in agreement that Schedule 40 can be used, even within a structure, for cold water?

    In Florida (which seems to be identical to IPC), distribution piping within the building cannot be Schedule 40, it has to be CPVC. Service piping to the building can be PVC.

    As I understand the code issue the distinction is between "service" piping and "distribution" piping. So I guess the practical question is where the dividing line is in a residential installation--for example, in the case of a well is it before the pressure tank or is it after POE water treatment equipment like a retention tank and whole house filters?

    I hardly ever deal with well systems. In a traditional system the service pipe is the pipe up to the structure. Everything within the structure is distribution piping.

    Everything I'll be installing is outside of the house in a detached garage. It will tie back into the pipe before it goes into the house and the water heater.

    In our area acidic water is quite common and it attacks the copper and leaches it into the water--not something you want in your drinking water. The choice of plastic over copper at least up to the acid neutralizing filter is a matter of health, not money.

    I would use PE pipe or sch 40 PVC but, do you have city water or your own well?

    Are you aware of the maintenance (cleaning and sanitizing) the 500 gal tank will require? How about potential water quality problems?
