When you run plumbing pipe through a home, there are a number of things to keep in mind as you go. There is only two main things to be concerned with, the high pressure pipes that bring water in from the city or your water well, and the pvc waste lines that take the used water out to the city sewer or your septic tank. Shut off valves and purges are used in all areas of the home to make shutting the water supply off easy, as well as purging air from your water lines. The entire system works on a flow of water in from your main water source, to going out through your drain system to the sewer or city septic, where it can reach the city treatment plant or your septic field.
Water Intake Mapping
The primary thing to think about when planning the routes of your plumbing pipe, is how the fresh water gets into the various areas of your home. This includes the bathroom, washroom, or even the kitchen and laundry room, any type of outdoor water access for gardening or other needs in the yard. You may also want to take into account for water needs for hot tubs or pool house, depending on the extensions you are planning for your property. All incoming pipes run through the existing walls and floors, where they are hidden from view until they reach the faucets, and this should be planned in your construction.
Shut Off Valves
All of your intake pipes should have shut off valves for each segment of your property, so that both hot and cold water can be shut off in the case of maintenance or emergency. The main lines coming from the city also have mandatory shut offs, which can be used to cut the flow to the entire home if needed. Your entire plumbing pipe system should have these shut off valve systems in place, as they are required by most city ordinances, for emergency purposes. There are many types of valves and shut offs that can be used throughout the home to cut off water flow to certain areas for maintenance and repair, making thing much simpler when working on piping issues in the future, should they arise.
Waste and Water Waste Removal
The last major feature of mapping out a solid plumbing pipe system is figuring the process of your water waste return. This is universal until it reaches the actual sewer line or septic sub system. Different regulations are used and followed when it comes to either hooking your home into a private septic field, or into a city sewer line. The entire waste system in your home should be planned to have drains with water traps running at an incline toward the main waste vent or main sewer drain. The top of this sewer drain has a vented end to allow air to enter the shaft allowing gravity to pull the liquid waste downward into the main sewer. Your entire sewer and drain system is made from pvc pipe, and all water intake is run through wall studs and floors with high pressure copper or brass pipe fittings.
