What are the Common Signs that my Septic Tank Needs Repairs?

Septic tank systems have plenty of advantages – from environmental friendliness to keeping you in control of your water bills. However, if you start to notice any of the following situations, it's time to call the plumbing experts at Mainstream for septic tank repair services:

Strange Smells

This smell is typically caused by the septic tank not disposing of waste properly. Your system may need repairs to resolve the issue.

Slow-Draining Septic System

Have you noticed that your toilets are draining slower than usual? If a clog in your home's plumbing is removed, and draining is still slow, your system may be full and require professional service.

Water Pooling on the Lawn

When a septic tank reaches full capacity, that liquid may rise to the surface of your lawn. If you see pools of water when the forecast is clear, it's probably time to call Mainstream for a septic tank repair cost estimate.

Very Professional

It was really shocking the amount of damage our pipes had and mr Johnson helped to explain what the issue was... He worked within our budget and created a couple of quotes with positive solutions. We went with the one we felt was necessary and he worked quickly getting that issue resolved. Very professional and knowledgeable.
