Professional Water and Sewer Line Repair and Replacement for Your Home

Water and sewer lines are the piping systems that enable potable water to enter and wastewater to exit your home. Damage to either of these plumbing systems can lead to frustrating problems, such as sewage backups and water damage. At Mark Allen, we can perform a variety of professional water and sewer line services to keep your plumbing system running smoothly.

We know just how disruptive damaged plumbing can be to your sense of comfort. That’s why we offer professional repair, replacement and maintenance services for homeowners in Bethel Park. Our team of friendly, experienced plumbers have the latest tools and technology to quickly diagnose and solve any issue with your water or sewer line.

Signs of a Damaged Water Line

  • Water pressure is falling: If you notice a decrease in your internal water supply in your home, it might stem from a leak or blockage in your water line.
  • Discolored water: Brown or rusty water coming from your faucets may be a sign of sediment buildup or corrosion in your water line.
  • Unusual noises: Whistling, gurgling or banging noises in your plumbing often indicates a damaged or obstructed water line.
  • Damp spots or pools of standing water: If you notice wet spots or standing water in your yard or home, it may be a sign of a leak in your water line.
  • Sudden increase in water bills: A sudden increase in your water bills without any corresponding increase in water usage may be a sign of a significant leak in your water line.

If you notice any of these signs, contact Mark Allen for professional water line repair and replacement services.

Signs of a Damaged Sewer Line

  • Slow draining or backups: If your sinks, tubs or toilets aren’t draining as consistently, it may be a sign of a clogged sewer line.
  • Unpleasant odors: Sewage odors coming from your drains or yard may indicate a damaged sewer line.
  • Wet spots or standing water: Wet spots or standing water in your yard may be a sign of a leak or break in your sewer line.
  • Mold growth: When mold or mildew appears near plumbing fixtures or on a wall unexpectedly, it may be a sign of a damaged sewer line.
  • Insect or rodent infestations: Sewer line leaks can attract insects and rodents, so when you’re suddenly dealing with an infestation, your sewer line may be damaged.
