Trenchless Technology

All that time and money spent on landscaping will not be lost when your water service needs replacement. Dwyer Plumbing offers a trenchless method to do underground utility work without digging up large sections of your yard or breaking up concrete or asphalt to get under a driveway or patio. We can also go underneath your home to get utilities from the front to the bank.

This trenchless technology, known as directional boring or horizontal directional drilling, allows us to install water lines, gas lines, telecommunications conduits, and power cable conduits without unsightly trenches. It may cost you no more than the traditional approach involving many hours of digging with a shovel or backhoe; it’ll certainly be quicker and leave almost no sign that you had major work done.

We know our trade. We’re here to help you.

About Water Service Lines

Water lines in Northern Virginia are made from a variety of materials:

  • Polyvinyl chloride (PVC)
  • Polybutylene (PB) “Big Blue”
  • Polyethylene (PE) Black
  • Galvanized iron
  • Copper

Each material suffers from different problems, any of which can result in something as severe as a thousands of gallons of water flooding your yard to low water pressure that take the enjoyment out of your shower. Low pressure can also be due to the location of your home in relation to the water main, which may require a pump to be installed. You could also have high water pressure that is causing problems with your appliances, which will require a pressure reducing valve to be installed.

If the water line is known to be plastic, the water authority wants them replaced without finding the leak. Polybutylene, commonly used from the mid 1970’s to the mid 1990’s but since deemed not up to building code, deteriorates due to chemicals in the water causing the pipe to develop tiny cracks from the inside out. And “Big Blue” (so called due to its color) is known to burst. It isn’t a matter of if it will leak but a matter of when; it commonly begins to develop noticeable problems around 10-15 years of age. Polyethylene, which is a black color, suffers similar problems as well.

If the water line is made of iron or copper then we can manually locate the leak. Galvanized iron usually starts rusting and developing problems after about 30 years, while copper should last for twice as long. Dwyer Plumbing will diagnose the issue and provide you with the most cost-effective solution, answer all of your questions, and will present you with a written proposal of the work to be performed, in accordance with our up-front customer assurance pricing. Your water service repair or water service replacement will be backed by our warranty.
