How to tap into main water line tends to be a question that quite a few people ask themselves. If you are one of those who require a water source for the sink or ice machine or the refrigerator water dispenser, there are numerous ways to tap into an existing water line these days.

Copper lines have the possibility of needing a particular set of utilities to touch the waterline, starting with plastic tubes that are less complicated and somewhat simpler to work with.

The different types of pipes that are already in place and frequently used in sprinkler systems are an attractive topic. How to locate the pipes for your system and dig the trenches can be a very debatable issue. Finally, you may want to discuss timers and their location.

The development to connect to the municipal water source tends to be too simple. Installing some elemental backflow prevention and putting pipes in the ground can connect the water to the main pipe.

One of the Determining Factors in this Matter

Is where the water comes from and how it is connected to it? For most people, the water source tends to be a municipal water line buried in the ground. But if it is connected by a well (which needs a pump), then the connection to the primary line is the same; however, we will not discuss the pump’s installation. Somehow, the primordial irrigation line will carry water from the source to the valves.

However, another thing you may want to consider is connecting your lawn irrigation system to your home’s plumbing system. This belongs to the final steps of the installation.

The water for your lawn’s irrigation system must come from somewhere, so you must connect your system to the home’s water supply.

How to Tap Into Main Water Line

Follow these steps to enter a water line.

Step 1

The primary irrigation pipe is a high-definition pipe. It must endure under recurring pressure.

This pipe should be assigned a higher pressure. To avoid breakage, the pressure rating of the pipe should be precise twice the actual water pressure.

This may seem quite a lot to you. However, you should bear in mind that with a certain increase in pressure in the system, this further categorization of the pipes is advisable.

However, the primary lines come in various materials and sizes. There is PVC, polyethylene, galvanized metal pipe, or copper metal pipe.

So we understand what our water connection is and where it is, the first thing to do would be to dig to show the water service line or show the existing tap, the faucet, etc.

When you turn off the primary water supply (which may be near your meter), you must open a tap to release the pressure that exists and avoid accidents.

Step 2

This water that comes to your property comes from space and arrives at your house.

So to have water for your sprinkler system, it is required that you branch off this line and run it to the valve box. It is best to do this by connecting a ‘Sliding T’ fitting, simplifying the repair/installation process.

These fittings accept that water will continue to flow from your meter into your home. This way, they accept that it is used for all your watering needs.

To arrange a Sliding Compression Tee, you must follow these four steps:

  • Clean the water service pipe
  • Cut a part of the pipe, half the length of the T
  • You will need to install a set of nuts and washers on each side of the pipe.
  • Insert the sliding tee and tighten the nuts with a wrench.

Process this by cutting the pipe that runs to the valve box. This is done to arrange a shut-off valve. It would help if you still had the mainline shut-off valve coming out of the water service line that will then enter your home; however, don’t forget to have one in addition to the main watering line.

It is best to have tapped into the existing water line running from the meter to the home separated from the sprinklers mainline. Quickly after branching off, we suggest you set up the gate or ball valve.

This makes it easy to shut off the water to the sprinklers without shutting off the water to the house.

Step 3: Reflux prevention

There is one valve that we will be able to see that is a 1″ double check valve group.

This valve is responsible for preventing harmful contaminants from returning to the water supply. It also works as the primary shut-off valve.

However, there is another type of backflow prevention gadget called an anti-siphon valve. These valves need to be positioned so that water drains out of the house.

In particular, the valves must be installed a minimum of six inches above the most prominent sprinkler head. There should be no back pressure on the valve or valve on the downstream side of the anti-siphon. A very important point to keep in mind is that having these gadgets in your line can keep the water safe.

Check with your code or local authorities to see what type of gadget is needed, how it should be installed, and who is authorized to install it.

Step 4: Connection of collectors

At this point, it is time to discuss how to arrange the valve box. You should dig precisely 8 to 14 inches, concerning the box, and put precisely two inches of crushed gravel.

This can accept that excess water and condensation will drain away without sinking the surrounding area.

At this step, you should place the base of the Orbit valve box over the gravel.

Before connecting the manifold to the primary line, you should open the primary shut-off valve to remove the dirt from the primary sprinkler line.

Now, you must set up your manifold. These manifolds install in minutes, work with Poly-Pipe and PVC systems, and expand to install a sprinkler system.

One aspect you may be interested in is the primary wiring for the timers. It is an acceptable initiative to carry out these connections at this time.

Step 5

When selecting your pipe type, remember that each has different assembly requirements.

PVC tends to be the most complicated because it is not very, but it is stronger. However, fittings have the potential to be complicated.

The use of this is required the use of two compounds (primer and cement).

First, it will be essential to place the primer, which works to subtly ‘melt’ the pipe and fitting, leaving enough space for them to slide together. The cement then forms a persistent airtight seal.

If you decide to use regular fittings, it is best to remember to follow the rules precisely as suggested, permitting the cement to dry completely (usually 1 to 2 hours) before running the water through the pipes.

Failure to do this may result in an incorrect adjustment of the glue, allowing water to leak or debris to enter.

When the pipe and fitting are joined, they cannot split or move, so be sure to place them correctly within the first 10-20 seconds of joining.

If you make a mistake, it will be essential to cut the fitting from the pipe (discard it) and attach a new fitting. The pipe can be reused, assuming that it is sufficiently extended.

The sprinklers that are installed will always be necessary for a house. However, the sprinkler system normally can facilitate the work at home.

Frequently Asked Question

How do you connect to a plastic water line?

Before you can add an outlet for a new faucet or other plumbing fixture, it will be critical to get into an existing tapping into the waterline.

For a home with PVC plumbing, this is an easy task that requires only a few utilities and some plumbing supplies. When you find a good pipe to connect, adding a fixture for a unique line only takes a few minutes. Follow the steps listed in the article read above, and everything will come out a winner.

How do you split a water line?

To split a water line, it is required to connect two braided supplies using the brass nozzle.

The drain uses rubber gaskets. It would help if you did not use putty and gaskets.

Some plumbers will use mastic or pipe sealant on the vertical threads. That’s the part that slides through the bottom gasket, the large washer, and the nut.

What is a dry faucet?

A dry faucet is simply touching an empty line or a pressurized container. Many of the virtues of this are shorter distribution times, usually a fraction of the value, less time than usual screwing, and decrease the danger of potential leakage by reducing the connections’ proportion.

What is a cold tap?

A cold tap makes it easier for us to get cold water for our personal use.

How does hot extraction from pipework?

Hot tapping strictly refers to the installation of pipe connections while in service. In the context of welding, it is frequently used for some welding on equipment in service.

Hot tapping is used continuously to recompose surfaces that have suffered mechanical damage or corrosion or add branches for system issues.

Last Words

We will have the possibility to say that it is too simple to install this kind of system; however, it is always favorable to communicate with an expert in the field. However, you will achieve your purpose with some patience if you follow the steps correctly.

Tapping water can help us improve our day today. Install a sprinkler system can bring many benefits to your home. Hope you have learned How to tap into the main water line.
