Pipe Rerouting in Troutdale: Should You Reroute, Repair, or Repipe?

When a pipe gives you trouble, you'll usually hear about three options. It's easy to mix them up. Each one solves a different problem. Pipe rerouting is the right call when the pipe itself isn't the issue. Where it runs is the issue.

• Repair: We fix the one spot that failed, like a cracked fitting or a single leak. It's quick and it makes sense when the rest of the line is healthy and sits in a good spot.
• Rerouting: We run a new section of pipe along a better path and shut off the old one. The old line might be buried under a slab, stuck in a cold outside wall, or blocking a remodel.
• Repiping: We replace the water lines throughout the house. That's for homes where the pipe material is worn out everywhere, not just in one place.

Here's a simple way to think about it. If the same pipe keeps leaking in the same area, patching it again won't change much. The pipe is still sitting where it got hurt the first time. Rerouting takes it out of that spot for good.

A slab leak is a good example. A water line under a concrete floor springs a leak. One fix is to break up the floor, dig down, and patch it. But that line is still under the concrete. If it leaks again later, you're back to breaking floor. Rerouting runs a new line through the walls or attic instead. The old pipe under the slab gets capped and left alone. For many homes that means less mess and fewer surprises down the road. When you just need that one spot handled, our slab leak repair page covers it.

Rerouting also isn't a whole-house job. If one stretch of pipe is the problem and everything else is in good shape, there's no reason to replace it all. On the other hand, if you're seeing pinhole leaks in several rooms, or the water looks off at more than one tap, the trouble may be the pipe material itself. In that case, rerouting one section won't get you far, and a full repipe may be the honest answer. Our pinhole leak repair and repiping pages explain those jobs in more detail.

So how do you know which one you need? Ask yourself a few questions. Has this pipe leaked more than once? Is it somewhere hard or costly to reach, like under a slab or inside a finished wall? Are the problems in one area, or all over the house? If the trouble keeps coming back to one spot that's hard to get at, rerouting is usually worth a look.

Our owner, Kevin Brain, has 20 years in the plumbing trade. We're licensed, bonded, and insured in Oregon (CCB# 257405). We'll tell you plainly which of these three fits your home. Sometimes it's the small repair, and when it is, that's what we'll say.

Rerouting is a good fix for the right problem. It's also more work than a lot of homes need. Here's when we'd tell you to skip it.

You had one leak in a spot that's easy to reach. If a pipe under your sink or in an open basement leaked once, and the rest of the line looks fine, just fix that spot. You can see it. You can get to it. If it ever leaks again, getting to it won't cost you much. Moving the whole line won't buy you anything there.

The pipe is hidden but hasn't given you trouble. A line under a slab or inside a finished wall isn't a problem just because of where it sits. Lots of pipes live in those spots for decades without a single leak. If yours is quiet, leave it alone. Rerouting a healthy pipe just in case is spending money on a problem you don't have.

The trouble is all over the house. As we covered above, leaks in several rooms usually point to worn-out pipe material, not one bad path. Rerouting one section won't stop the next leak somewhere else. That's a repipe conversation. It's better to have it up front than after you've paid for a reroute that didn't help.

Your real complaint is weak water pressure. Low pressure has a lot of causes, and many of them have nothing to do with how your pipes are laid out. A worn pressure regulator, for example, can make every tap feel weak. Swapping that part is a much smaller job than moving pipe, so it makes sense to check the simple causes first.

A pipe froze one time in a bad cold snap. One freeze doesn't always mean the pipe has to move. Often the answer is better protection right where it is. A few things you can do yourself:

• Put foam pipe sleeves on lines you can reach in the garage or crawlspace.
• Unhook garden hoses from outside spigots before winter.
• Open the cabinet doors under sinks on outside walls when it gets very cold, so warm air can reach the pipes.

If the same pipe freezes again after you've protected it, that's when moving it inside starts to make sense.

You're planning a remodel soon. If you plan to redo the kitchen or bathroom in the next year or two, it's often smart to wait. Fix the current problem with a simple repair for now. Then reroute while the walls are already open for the remodel. You'll pay for the wall work once, not twice.

You aren't sure where the water is coming from yet. Don't decide on a reroute until you know which pipe is leaking. A wet ceiling or a damp floor can come from a spot several feet away. Finding the real source comes first. Once you know it, the right fix is usually pretty clear.

If any of these sound like your situation, rerouting probably isn't your best move right now. That's a fine answer. The goal is to fix what's wrong in your home, not to do the biggest job on the list.

Moving a water line changes how water flows through your home. That's why a reroute often needs a plumbing permit and an inspection. A lot of people see permits as red tape, but for this kind of job they work in your favor. A permit means someone who doesn't get paid for the job takes a look at it. That's a second set of eyes on pipes you'll likely never see again once the drywall goes back up.

The rules depend on the size and type of the job, so we won't guess at them here. In Troutdale, the local building department can tell you whether your project needs a permit. Your plumber should be able to tell you too. Either way, settle this before work starts. Don't leave it for after.

Skipping a needed permit can cause trouble later. When you sell your home, a buyer's inspector may ask about plumbing work that has no record. An insurance company may have questions after a leak in a line nobody signed off on. A permit and a passed inspection give you a paper trail that shows the work was done the right way.

Pressure testing is how you find out a new line is sound before it disappears behind a wall or above a ceiling. The plumber fills the new pipe and raises it above normal pressure. Then they leave it there for a while and watch a gauge. If the needle holds steady, the joints are tight. If it drops, there's a leak somewhere, and it's easy to find and fix while everything is still open.

This matters more on a reroute than on a simple repair. A reroute often has fittings in spots you'll never see again, like inside a wall cavity or up in the attic. A slow drip in one of those places can soak insulation or rot wood for months before you notice a stain. Testing at higher pressure than your home normally runs puts extra stress on every joint, so a weak one shows itself now instead of a year from now.

You don't need to know plumbing to check that these steps happen. Just ask a few plain questions:

• Does my job need a permit, and who's pulling it?
• Will the new line be inspected before the walls are closed?
• Will you pressure test the new pipe, and can I see the gauge?
• What happens if the test or inspection finds a problem?
• What's your CCB number, so I can look you up?

That last one is worth asking any contractor. Oregon's Construction Contractors Board lets you look up a license number and see whether the business is active and bonded. Ours is CCB# 257405. Go ahead and check it. A good plumber won't mind any of these questions, and should be glad you asked.
