FAQs

Common Answers To Your Questions

Have questions? We are here to help. Still have questions or can't find the answer you need? Give us a call at 636-538-5179 today!

  • How do I know if I need to replace a main water line?

    This is usually a matter of age and condition. If the pipes in your home are older than 50 years or so, you should be checking them regularly for signs of rust or corrosion. Corroded water lines need to be replaced right away.

  • What can I do about a leaky faucet?

    Often, a leaky faucet is caused by a corroded O-ring, gasket, or valve seal. Try shutting off the water and removing the faucet handle. You may be able to fix the problem by tightening the nut that holds all the internal parts in place. You may also want to try disassembling the faucet to inspect its components. If you notice a part that is broken, replacing that part can do the trick. If you continue having problems with a dripping faucet, give us a call.

  • Is there a way to prevent clogged drains in my house?

    Yes! First of all, don't put things down your drains that don't belong there: this includes hair, oil or grease, coffee grounds, hard food and egg shells. A drain stopper or filter can also stop larger materials from going down your drain and clogging it.
