Dane Larkin · Customer review · Apr 2026
Bryant saved my bacon. Hanging drywall I put a drywall screw in our water main into the house about 1" above concrete. Bryant was at my house within 45 minutes on a Saturday and working on it. He had to cut out a little concrete to make the fix and was done within a couple hours. Highly recommend. The fix was well done and tidy.
Brian Ahlers · Customer review · Apr 2026
Bryant answered my request to fix a leaking pipe in my garage. The pipe had separated. He came the same day to fix this problem. ... Bryant is respectful, knowledgeable, and goes way out of his way to help his custermers. I will hire him again as plumbing issues arise. Thanks, Bryant.

Plumbing and septic FAQ
Questions we hear from Helena customers
Straight answers to common plumbing and septic problems. Still stuck? Ask for a free quote.
Get a Free QuoteWhat should I do if sewage comes up through a floor drain?
Stop using water throughout the property, since every running shower, sink or washing machine sends more wastewater toward the affected drain. Keep children and pets away, and avoid walking through the water because sewage can carry harmful germs. Note which fixtures were running before the backup started. That detail helps the plumber tell whether the problem sits in the main sewer line rather than the drain itself.
Can I wait until morning if a plumbing leak seems small?
Sometimes, but it depends on where the water goes. A slow drip into a sink is different from water reaching a wall, ceiling, cabinet or electrical area. If a fixture valve stops the flow, you can usually wait. If the source cannot be controlled or keeps soaking building materials, call right away. A+ 406 Waterworks offers emergency plumbing help 24 hours a day.
Why did my water bill jump when I cannot see a leak?
Water can escape where you never see it, such as a toilet, a supply line or a buried pipe. If your household use has not changed, a higher bill is worth checking. Compare your meter reading before and after a few hours with no water running, and note any damp spots or low pressure. Leak detection confirms where the water is going before any repair is planned.
What should I do if my septic alarm starts sounding?
Do not ignore it. A septic alarm can mean the liquid level is higher than expected or another part needs attention. Cut back on laundry, long showers and other heavy water use until the cause is checked, and never open the tank or touch its electrical parts. Note when the alarm started and any recent heavy water use, power loss or weather change, then arrange a septic inspection.
Why does a sewer problem keep returning after drain cleaning?
Drain cleaning clears a blockage, but it cannot fix a cracked, collapsed or root-damaged pipe. If a backup returns soon after cleaning, the sewer line itself may be the problem. Keep your service records and note which fixtures were affected before and after. That history helps show whether a repeating issue points to sewer line repair rather than another simple clog.
What should I do if a pipe bursts while I am away from home?
Shut off the main water supply as soon as you can reach it safely, and stay clear of standing water near outlets, appliances and the electrical panel. Take photos before cleanup if you need records. Then tell the plumber where the break is and whether water is still flowing. Stopping the water comes before any work to restore the damaged room.
