Best Ways to Install Plumbing Pipes Without Disruption

It is important to install plumbing pipes in a proper and well mannered way not only for the smooth flow of water but also to ensure no leakages in the future occur. Below, we will be explaining a few methods of joining pipes and fittings so that the plumbing system could be installed without any disruptions.

Solvent Cement Welding (CPVC) Install Plumbing Pipes

CPVC pipes and fittings use a joining method known as solvent cement welding. It is a fast, safe and reliable way to install plumbing pipes. Moreover, it is easy to do and saves time and money. Solvent cement welding joins the pipe at a molecular level, making cohesive bonds and creating a strong joint there. Following the instructions below, the contractor or even a homeowner can install plumbing pipes in a CPVC piping system.

Step 1: Cut The Pipe

CPVC pipes need to be cut square, to ensure maximum binding surface. Any cutting tool such as ratchet cutter, hand or circular saw could be used for cutting CPVC pipes this way. Ensure the pipe is not cracked or damaged during the cutting and the cut is smooth.

Step 2: Prepare and Apply Cement

Now prepare the pipes and fittings. After you are set, use a dauber that is no more than half the diameter of the pipe to apply the solvent cement. Manufacturer’s manual could be referred for more specific instructions. Thick coats of the solvent cement should be applied uniformly, both on the outside of the end of the pipe and inside of the pipe. Make sure there are no drips.

Step 3: Assemble the Joint

Fit the pipe in the fitting as soon as applying cement. Otherwise, it can result in the evaporation and drying of the solvent cement. After inserting pipe into the fitting, make sure it goes till the end and fits in there properly.

Step 4: Give Joint some Time

After the joint is set, give it some time for the solvent to evaporate out of the joint. This time is called cure time and it should be mentioned on the cement’s manual or box. After this time has elapsed, the joint is all set to be tested.
In this way by joining the right kinds of pipes and fittings, the ultimate desired plumbing system could be installed without disruption.


  • This process requires no electrical equipment
  • CPVC joining doesn’t require heat fusion
  • No heavy lifting since they are lightweight
  • Saves labor cost
  • Saves money
  • Reliable in the long term


Electrofusion Welding (HDPE) Install Plumbing Pipes

This welding method is used to join HDPE pipes and fittings, besides the butt welding technique. It is done by using heating resistors inside the fusion fitting. This method therefore, requires electric supply, specific tools and a skilled hand for both the electrical equipment and the pipes. It equips special type of fittings that have resistor wires inside them, which function to hear and join the pipe with the fitting when connected to electric power. This joining of HDPE pipes is done by the following steps:
In this way by joining the right kinds of pipes and fittings, the ultimate desired plumbing system could be installed without disruption.

Step 1: Prepare The Pipes

Firstly, it should be made sure that the pipes are free from unacceptable cuts and defects. Pipes and fitting surfaces should be clean and dry. In this way, the pipes are prepared for the welding joint.

Step 2: Insert Pipe Inside the Fitting

After the first step, the next step is to adjust the pipe in the special fitting made for this piping system. It should be made sure that the HDPE pipes are placed properly in the fitting.

Step 3: Electric Fusion

In this step, the ends of the welding machine supplied by electric power are connected with the electrofusion fitting. Electric current flows through the resistor wire inside the fitting, heating it and ultimately joining the pipe with thr fitting.

Step 4: Let the Joint Dry

After the above heating step time of several seconds, it is the time to let the joint cool down. It takes from half a minute to longer depending upon the width of the pipe and its manufacturing.
This method is according to the optimal standards and can be used to join pipes of varying diameters. It provides reliable connections between the components of a plumbing system.

Butt Welding (HDPE) Install Plumbing Pipes

For HDPE, the butt welding is the most common method used to install plumbing pipes and fittings. For this welding method, a butt welding machine is needed. HDPE pipes and fittings can be installed by following these simple steps by this method.

Step 1: Prepare The Pipes

First of all the pipes should be checked for cracks or any sort of damage. Then both the ends of two different pipes should be cut properly.

Step 2: Joining By Welding Machine

The ends of the two pipes are heated by the butt welding machine for the purpose of being joined together. It has a specific heating time after which the heating is stopped.

Step 3: Applying Pressure

Pressure is applied on the pipes against each other when their ends are facing each other. This step should be done as soon as possible after heating by the welding machine. The pipes are held against each other for a specific time duration.

Step 4: Let the Joint Cool

After joining, the joint is given some time to cool down before it is tested.
Butt Welding method can be used to join HDPE pipes of different ranges of widths. It is in accordance with the piping standards.

Comparing Butt Welding & Electrofusion Welding

Both these pipe joining methods are used for HDPE pipes and fittings. Both are in accordance with the piping standards. It is important to use the right method in the right place to install a plumbing system without disruption.
The butt welding method is more convenient and less costly. However in some cases, such as when the butt welding could not fit in the tight spaces needed, electrofusion welding does its job without any problems. Moreover, electrofusion welding is also a very good option since only electric supply from outside can join the pipes as heating resistors are present already inside the fittings.


So now you know about the best ways to install plumbing pipes without disruption. HDPE pipes and fittings have to be joined by welding methods which require a skilled and familiar hand to operate the machinery and install those pipes. However, joining of CPVC pipes and fittings by solvent cement is a relatively easy method and a person just a bit familiar with the basic techniques can do the installation of CPVC pipes in Pakistan. CPVC pipes and fittings in this way are easier to install. All these methods to install plumbing pipes are of international standards and ensure flawless installation of plumbing pipes.
