“Referred by my family”
“At a family recommendation, I called Mallick Plumbing to get a new ball valve, piping and pressure valves, all of which had minor leaks. A few days after the call, our technician, Luis, came out right on time and started work immediately. He was very professional and efficient at getting these fixes completed. He kept the area clean and answered a few questions about the install. I would definitely recommend Mallick Plumbing. Very reasonable price for professional quality work!”

Popular Water Line Questions from Customers

What causes water line leaks?
Leaks can result from corrosion, soil movement, freezing temperatures, tree root intrusion, or aging piping materials.

How do plumbers detect underground water leaks?
Professionals use acoustic sensors, pressure testing, and moisture detection equipment to locate leaks accurately.

When should a water line be replaced instead of repaired?
Replacement is recommended when pipes are severely corroded, collapsed, or experiencing repeated leaks.
