A pressure reducing valve, or PRV, controls how much water pressure enters your home. When it starts to fail, the warning signs often show up gradually, which makes them easy to overlook until damage is already happening.
Signs your PRV may be failing include:
Low or inconsistent water pressure. You may notice weak flow at multiple faucets or pressure that drops sharply when more than one fixture is running. This often worsens over time and can affect the entire home.
Unusual noises when water is running. Humming, squealing, or knocking sounds when faucets turn on are commonly linked to unstable pressure inside the valve and indicate added stress on your plumbing system.
Excessively high water pressure. Some PRVs fail by allowing too much pressure into the home. While this may not be obvious right away, it can wear out pipes, fixtures, water heaters, and appliances. Banging pipes, known as water hammer, are a common warning sign.
Visible leaking near the valve. Because PRVs are usually installed near the main water line, leaks may show up as soggy soil, standing water in the valve box, or unexplained moisture near the foundation.
The most important thing to know is that waiting for a PRV to fail completely can lead to burst pipes, appliance damage, and expensive emergency repairs. That’s why Mainstream recommends having pressure issues evaluated early. Our technicians test water pressure, inspect the PRV, explain what’s happening in plain terms, and provide honest recommendations. If repair or replacement is needed, it’s handled correctly so your plumbing system is protected long-term.
In many cases, a broken sewer line can be repaired without traditional excavation thanks to modern trenchless sewer repair technology. These methods allow plumbers to fix underground sewer lines while preserving landscaping, sidewalks, and driveways.
The process typically begins with a sewer camera inspection, which allows a professional to see the condition of the pipe from the inside and determine the best repair approach. Depending on the extent of the damage, one of two trenchless methods may be recommended:
Trenchless sewer repair is often faster, less disruptive, and more cost-effective than traditional excavation, but it isn’t the right solution in every situation. Severely collapsed pipes or complex sewer layouts may still require conventional repair methods.

The cost of a plumbing inspection in Spokane Valley depends on how detailed the inspection is and what tools are needed to properly assess your plumbing system.
For most homes in the Spokane Valley area, a basic plumbing inspection typically falls around $200, though pricing can vary based on the scope of work.
Visual plumbing inspections are usually on the lower end of the price range. These focus on exposed pipes, fixtures, water pressure, and visible signs of leaks or corrosion.
Camera-assisted inspections cost more due to the specialized equipment involved. When a sewer camera or drain camera is needed to inspect underground or hidden lines, costs can reach $400–$500, especially in older homes or properties with mature trees.
Many Spokane Valley homes have a mix of aging plumbing and newer additions, which is why camera inspections are often recommended when buying a home, dealing with recurring drain issues, or investigating suspected sewer problems.
If an inspection uncovers an issue, repair costs can vary depending on access, pipe condition, and how far the problem has progressed. Addressing issues early usually helps avoid much larger expenses later.
Common plumbing repair ranges in the Spokane Valley area include:
Local factors like soil conditions, freeze-related damage, and root intrusion can all influence repair complexity and cost.
Even when an inspection reveals a costly repair, catching problems early can help prevent water damage, sewer backups, and emergency plumbing situations — which are typically far more expensive and disruptive for Spokane Valley homeowners.

In many cases, yes — your policy will cover the sudden water damage caused by a burst pipe, but not the cost to repair or replace the frozen pipe itself. Whether you’re covered often depends on your specific policy and the steps you took to prevent freezing. Knowing what’s typically covered, what to do right away, and how to file a claim can save you a lot of stress when Spokane’s temperatures drop below zero.
If you need fast help with pipe repair or winterization, Mainstream Electric, Heating, Cooling & Plumbing is here for homeowners across Spokane and Northern Idaho with licensed plumbers who move quickly and do it right.
Frozen pipes happen when the water inside your plumbing drops below 32°F, expands, and blocks the line. That pressure can split the pipe and send water through walls, ceilings, and floors — sometimes in minutes. The good news: many standard insurance policies cover the sudden and accidental water damage that follows a burst pipe. The catch? The repair or replacement of the actual frozen pipe usually isn’t covered.
So when people ask, are frozen pipes covered by insurance? the short answer is: “The water damage is covered — the pipe repair isn’t.”
Coverage is more likely when the damage happens suddenly and you’ve taken reasonable steps to keep your home heated and protected. If your heat was off or the pipes weren’t insulated, your claim could be challenged. Policies also vary for vacant or unoccupied homes that weren’t properly winterized.
Here’s what often affects coverage:
When a pipe splits, water spreads fast — soaking drywall, buckling floors, and sometimes reaching electrical lines. Damage can grow within hours, and mold can start in a day or two. Acting quickly can limit the destruction and help your claim.
Here’s what to do right away:
Quick action not only reduces repair costs but also shows your insurer that you did your part to mitigate the loss — something they look for when reviewing claims.
A successful claim starts with good documentation.
Take wide and close-up photos of all affected areas — ceilings, walls, floors, and personal belongings. Keep receipts for supplies and professional services. Note when you discovered the problem, what you did, and when help arrived.
When you report the loss, describe it as sudden and accidental. Share the preventive steps you took, like keeping your thermostat set, insulating pipes, and shutting off outdoor spigots. Ask your agent:
Mainstream provides licensed plumbing repairs and clear service records that can support your claim. If your adjuster asks what caused the problem, you’ll have professional documentation showing you acted quickly and responsibly.
A little preventative steps for freezing pipes goes a long way — and it can make all the difference for your insurance coverage.
Before the next cold snap:
If you’ve noticed recurring cold spots or reduced water flow on freezing mornings, a plumbing inspection from Mainstream can pinpoint risks and recommend lasting fixes before trouble starts.
Here in the Inland Northwest, winter can swing from mild to bitter in a day. Wind, sudden cold snaps, and power outages raise the risk of freezing — especially in homes with plumbing in crawl spaces, garages, or exterior walls. Even outbuildings and shops with running water need attention.
Before temperatures plunge, schedule a pre-season plumbing check, protect outdoor spigots, and confirm that warm air reaches vulnerable areas. If you’ve remodeled or rerouted lines, it’s worth having a professional make sure everything’s ready for the next cold front.
If you suspect a freeze, hear ticking or banging in the walls, or see damp spots after a cold night, don’t wait. Mainstream’s licensed plumbers are on call 24/7 for emergencies throughout Spokane and Northern Idaho.
We’ll find the source, stop the leak, and help you understand what comes next — from repair to prevention. We can even guide you through documenting damage for your insurance claim.
At Mainstream, we believe in honest advice, fair pricing, and work done right the first time. Whether it’s a frozen pipe or a full winterization service, we’ll make it right — and you can count on Mainstream.
