How To Plumb an In-Ground Pool

House with pool

An in-ground pool is a very welcome addition to any home. It enhances the beauty of your garden and your home and will provide you hours of relaxation and fun and a welcome respite from the heat during the summer months. A swimming pool is an expensive addition to a home and it requires constant maintenance to keep it clean, sanitary and safe for everyone who wants to take a dip.

One important part of a swimming pool is the quality of plumbing that has been installed. It is a permanent part of the pool and should be installed with care to ensure that it will perform perfectly for a number of years. As the plumbing lines are embedded in the ground along the sides of the pool, it will be very expensive and disastrous if the plumbing malfunctions.

Trying your hand at plumbing an in-ground pool can prove to be a very long and tedious process. It can still be done. Here are some tips.

  1. Do your own research. There are dedicated websites in pool construction and plumbing. Check pool supply manufacturers’ websites and learn as much as you can before you start this project. Look at expert instructions and designs that match your own pool design and shape so that you will have a fair idea of what is to be done and the materials that you will need.
  2. Check your local area building codes. If you are connecting the pool drain to a city sewer system you may need the services of a licensed plumber to attach the deep seal trap.
  3. Your pool filter system should be plumbed using ridged schedule 40 PVC and Flexible schedule 40 PVC pipes. Use the ridged pipes for the straight lines and the flexible pipes that can be bent around the corners without using elbow fittings. The flexible pipes will help prevent leaks and system failures since these do not need additional fittings or couplings. The flexible pipes can save you time as these can be installed faster.
  4. Choose an in-floor system for suction and water sanitization systems for easier maintenance of the swimming pool. Choose an in-floor system where the total pool suction is at the main split drain where all the dirt is collected. For better quality of return lines, use 2.5-inch suction lines, dedicated split drains and dedicated vacuum lines instead of the standard 2-inch lines.
  5. Install two pool skimmer lines. One should run from the skimmer to the main drain. Install another one from the main drain to the pump hose. Use the same type of pipe that you used for the skimmer’s drain.
  6. Sloping the suction line that will run from the pool to the pump will prevent air lock. The same angle of slope should also be applied to the skimmer line.
  7. Silica sand should be used in the sand filter’s tank. Install the inlets through the floor of the filter house and put together the filter and the plumbing before installing the liner. Do not add any chemicals in the water until you have ensured that the filter is working properly. Inspect the filter and pump lines for leaks. Put in the back fill if you are very sure that no repairs are required.
  8. The right voltage needed to run the pool pump motor is 220 volts. Make sure that you have the proper voltage to avoid short-circuiting the pump.

Ensure that you have the right swimming pool plumbing equipment and never compromise quality. Make sure that you are buying a reliable brand. Check all the features and read all the manufacturer’s terms and conditions for your safety and peace of mind.
