Know the warning signs
Signs Your Water Line
Needs Attention
Wet or soggy spots outdoors
Unexplained wet ground, pooling water, or a soggy area in the yard can point to a leaking water line.
Low or changing water pressure
Pressure that drops or fluctuates can have several causes, including the water line. An inspection helps narrow it down.
A higher water bill
A bill that climbs with no change in how you use water can be a sign of a leak.
Discolored water
Water that looks brown or rusty can come from more than one source, including aging piping.
Corrosion or damage on exposed piping
Visible wear, corrosion, or damage on exposed water piping is a reason to have it inspected.
Aging piping or repeated repairs
Older water lines and repeated leaks deserve a closer look. Age alone does not always mean replacement.
Not sure what is going on with your water line? Call us or send a service request and Romero Bros will take a look.
Your options
Repair Or Replace?
We Will Explain Your Options.
When Repair May Make Sense
Some problems are limited to one section or connection. Whether a repair makes sense depends on what is damaged and on the condition of the rest of the line.
When Replacement May Be Recommended
Replacement may be recommended when a line is badly damaged, deteriorating, or leaking repeatedly, so that patching it is unlikely to solve the problem.
The right recommendation depends on your specific water line. Romero Bros bases it on inspecting the line, then explains the options so you can decide what works best for your home.

Questions
Water Line
Questions
Should I repair or replace my water line?
It depends on what is wrong and on the condition of the line. Romero Bros can inspect it and explain your options, so the recommendation fits your actual plumbing.
Do you replace water lines?
Yes. You can see a residential water line replacement in the project photos above, from excavation and connection work through the finished exterior connection.
Will my yard need to be dug up?
It depends on where the line is and what the problem is. Our water line replacement project involved excavation. Romero Bros can explain what your situation is likely to involve once they have looked at it.
What can cause low water pressure?
Several things, including a leak, a worn pressure regulator, or the condition of the piping. A plumber needs to inspect your system to say which applies.
What should I do if a water line bursts?
If you can do so safely, shut off the main water valve to limit the water, then call (626) 826-7743. If you smell gas, leave the area and call your gas utility or 911.
How do I know if my water line is leaking?
Signs include wet or soggy areas outdoors, a higher water bill, and changes in water pressure. These do not confirm a leak on their own, so an inspection helps.
