Why does my well water smell like rotten eggs?

A sulfur smell is usually caused by hydrogen sulfide gas naturally occurring in groundwater or by sulfur-reducing bacteria in your well. This is common in North Houston and treatable with shock chlorination or a filtration system.

How do I know if my well has bacteria?

There are often no visible signs of bacterial contamination. The only way to confirm is through professional water testing, which 77 Water Well recommends annually.

What causes low water pressure in a well system?

Low pressure can be caused by a failing pump, waterlogged pressure tank, clogged pipes, or sediment buildup. Our technicians diagnose and fix the cause quickly.

How often should a private well be inspected?

The National Ground Water Association recommends a professional well inspection at least once every 10 years, with annual water quality testing.

What is well plugging and when is it needed?

Texas State Law requires landowners to plug all abandoned or unused wells to protect the water supply. 77 Water Well Inc. is licensed to handle all well plugging in Texas.
