Installation of PEX plumbing systems ought to be carried out strictly according to the project in hand. Usually, PEX plumbing systems are installed by educated specialists with technical understanding of the program. But if you want to set up PEX plumbing systems on your personal then there are specific items you would have to maintain in thoughts ahead of you set out to do the actual activity of installing a complete-fledged PEX plumbing program.

What is PEX?

Firstly, you have to know what PEX is. For the uninitiated, PEX is cross-linked polyethylene. These are normally utilised for radiant heating purposes, but now these are also utilised extensively for hot and cold plumbing installations. PEX tubing and plumbing systems are quick to operate with given that they are very versatile. This is one particular benefit PEX systems have more than regular copper systems. Owing to its design and style, PEX is also extra sturdy below temperature extremes and chemical attack. It is also hugely resistant to creep deformation. Actions to be followed though installing PEX:

Beneath is a basic step by step guideline on how to set up such a plumbing program. Just stick to these measures meticulously and you will be in a position to set up a PEX plumbing program at your dwelling with out the aid of any technician. It will also save you some added bucks.

Factors needed for installing a PEX Plumbing program:

  • PEX piping and fittings
  • PEX crimps
  • PEX manifold with ball valves
  • Nailing plates
  • PEX stub outs


  • Hammer
  • Soldering machine
  • PEX cutting equipments
  • Straps
  • Hangars
  • Paddle bit
  • Crimp gauge
  • Ideal-angle drill


Gradually start out drilling immediately after you have placed the bit up to the stud. Raise your drilling speed as you move forward. Whilst drilling, just make positive that every single hole is at the exact same level so that the pipe can run parallel to the floor. Also drill by way of the sill plate and sub-floor for person water lines.


Following you are carried out with drilling, insert and run the water lines by way of these holes. In most situations, the water lines come by way of the floor. But in specific other situations, the lines might come by way of the wall studs. In these situations, make positive you drill the holes suitable at the center so that though hanging the board, the screw and nails of the board do not harm or harm the pipes in any way.


Pull the lines upwards by way of the holes on the sub-floor. Also, run the other finish to the region exactly where water will be coming into the dwelling. Leave pout some added pipes on each the ends. Now use the clamps and safe the lines to the joists. Make positive, you maintain the hot and cold lines as far apart as achievable to lessen heat transfer.


Now do the rough stub-outs for the sinks. You can use a suitable-angle drill or a paddle bit to carry out this activity. Just make positive to reduce-off the rough fitting cap and set up finish valves immediately after you place up the walls.


It is now time to set up the crimps. For the fantastic crimp set up, make positive the PEX is straight when you reduce it. Now slide a crimp ring onto and then insert the pipe in the crimp fitting. Use slip-joint pliers to slide the crimp ring up. Do not do it with your fingers, or else you may hurt oneself though tightening the crimp ring. Make positive the crimp ring is 1/eight inches or 1/four inches from the finish of the pipe.


Now rough the lines to the fixtures. Do not solder about the PEX tubing or you may finish up damaging the pipes. You ought to use a fitting referred to as PEX 90. Following it has cooled from soldering, you can match it onto the PEX water line.


Position the valve in a way exactly where they will face down when they are hung in their areas. Solder them to their positions.


You can now pull up the water lines from the crawlspace and connect them to the manifold. Screw the leading brackets to stud maintaining them at eye level. Also set up the bottom brackets to the manifold.


Now mark all the holes with a nail and start out drilling them. Just make positive you do not harm the manifold though you are performing your drilling operate. Place the manifold on the ground immediately after you have completed you drilling operate.


Now you can attach the PEX ball valves to the manifold. Screw each and every valve onto its port adequately. Get one particular of the lines and pull it up to the valve to make positive it fits adequately. This sort of arrangement will imply that every single fixture will have its personal shut-off valve.


Following you are carried out with fitting the ball valves, you can now pull up the PEX tubing from the crawlspace and attach them at their areas.
