Frequently Asked Question

Plumbing FAQs

Why is my toilet constantly running or leaking water?

A constantly running toilet is usually caused by a worn flapper, faulty fill valve, or improper float adjustment. These parts wear out over time, causing water to leak from the tank into the bowl. Replacing the flapper or fill valve typically solves the problem

What causes low water pressure in a home?

Low water pressure can come from several sources: buildup in pipes, corroded plumbing, a partially closed shutoff valve, or a failing pressure-reducing valve. In some cases, the issue comes from the municipal supply. MVP Plumbing can test your system to pinpoint the cause.

How often should plumbing be inspected or serviced?

A full plumbing inspection every 1–2 years helps prevent costly leaks and catch small issues early. Homes with older plumbing or well systems may benefit from annual checks.

What causes discolored or rusty water from taps?

Rust-colored water often comes from corroding galvanized pipes or sediment inside your water heater. It can also indicate high iron content in your water supply. Some instances it could be sediment build up in a water heater tank that is leaching into the hot supply.  A plumbing inspection or water test can confirm the source.

 Is it safe to use chemical drain cleaners?

We don’t recommend it. Chemical drain cleaners can damage your pipes, create toxic fumes, and offer only a short-term fix. Mechanical drain cleaning or hydro-jetting is safer and more effective.

What should I do if there’s a burst pipe?

Immediately shut off your main water valve, then turn off your water heater and open nearby faucets to relieve pressure. If you are an MVP client, your main shutoff is likely already tagged with a yellow or orange tag. If you are unsure where your main shutoff is located, please call MVP so we can identify and tag it for you.

How do I locate my main water shutoff valve?

The main shutoff is typically located near where the main water line enters your home, often in the basement, crawlspace, or utility room. We recommend tagging it clearly so every family member knows where it is. If you are an MVP client, your main shutoff is likely already tagged with a yellow/orange tag. If you are unsure where your main shutoff is located, please call MVP and we will come out to identify and tag it for you.

Why are my faucets or fixtures dripping?

A dripping faucet is usually caused by a worn washer, cartridge, or O-ring. Even a small leak can waste hundreds of gallons of water per year, so it’s best to repair it promptly. Common factors that contribute to these parts wearing out include high water hardness, elevated chlorine levels, or excessive water pressure. At MVP Plumbing, we test your home’s water quality and water pressure at the start of every new client visit to help identify these issues early.

How long does a water heater last?

Traditional tank-style water heaters typically last 8–12 years, while tankless models can last 20 years or more with regular maintenance. Annual flushing and water treatment helps extend lifespan.

Why does my drain or sewer smell sometimes?

Foul odors usually come from dried-out P or S-traps, venting issues, or buildup in the drain line. Running water through seldom-used drains or having your lines cleaned often resolves the issue.

How can I prevent frozen pipes in winter?

Insulate pipes in unheated areas, disconnect outdoor hoses, and keep a slow trickle of water running during extreme cold. If you travel, set your thermostat no lower than 55°F.

Why is my water bill suddenly higher?

Hidden leaks, running toilets, or underground pipe damage can cause unexpected spikes in your water bill. A simple water meter test can reveal whether there’s a leak somewhere in your system. If you suspect an issue, call MVP Plumbing to schedule an inspection for hidden leaks, and contact AQUA to have them check your meter for accuracy.

What shouldn’t I put down my drains?

Avoid pouring grease, coffee grounds, wipes (even “flushable” ones), and fibrous foods down your drains. These items are the most common culprits of stubborn clogs.

What causes frequent clogged drains?

Buildup of hair, soap scum, grease, and debris over time. Consistent maintenance, drain strainers, and professional cleaning prevent recurring clogs.

Water Filtration FAQs

Why is my toilet coWhat contaminants can a whole-house filtration system remove or reduce?nstantly running or leaking water?

Whole-house filtration systems can reduce sediment, chlorine, rust, and heavy metals, along with many other impurities found in tap water. Depending on the system type, advanced setups can also reduce PFAS, lead, volatile organic compounds (VOCs), herbicides, pesticides, and other chemical byproducts. This not only improves the taste and safety of your water but also helps protect your plumbing, appliances, and clothing.

Do I need a whole-house system or just a drinking water filter?

It depends on your water quality and what you want to improve. Whole-house systems treat every drop coming into your home, helping protect your pipes, laundry, appliances, and even your hair and skin. Drinking water systems, like reverse osmosis units, provide highly purified water at one dedicated tap for cooking and drinking. Many homeowners choose to combine both for complete, whole-home protection.

How do I choose the right size or capacity for my water filter?

The best system depends on your home’s water usage, flow rate, and water chemistry. MVP Plumbing starts with a professional water test, then recommends a properly sized system designed for your household’s specific needs.

How often do filters, media, or membranes need to be replaced?

Most carbon filters need replacement every 6–12 months, sediment filters every 3–6 months, and reverse osmosis membranes every 2–3 years. Frequency depends on your water quality and daily use — and we offer maintenance reminders so you never have to guess.

Will a filtration system reduce my water pressure?

When properly sized and maintained, it shouldn’t. If filters become clogged or undersized, pressure can drop. Routine maintenance ensures smooth flow and consistent performance.

Do filtration systems remove or reduce chlorine, lead, PFAS, or bacteria?

Yes, with the right combination of technologies. Activated carbon filters reduce chlorine and help remove chemical tastes and odors. Reverse osmosis systems target lead, fluoride, PFAS, and many dissolved contaminants. UV or specialty filters are used to neutralize bacteria and microorganisms. We recommend the best setup based on your water test results so your system is matched to your home’s specific needs.

Is your team certified to install water treatment systems?

Yes. Our team includes a certified installer and a certified water treatment specialist through the Water Quality Association (WQA). This ensures that every system is installed correctly, safely, and in alignment with industry best practices.

What maintenance does a filtration system require?

Most systems need only periodic filter changes and occasional inspections. We offer ongoing maintenance plans to ensure your system runs efficiently and your water stays in tip top shape year-round.

Can a water filtration system increase utility costs?

No, filtration systems don’t use significant electricity (and some use none). They can actually help lower costs by extending the life of your appliances and plumbing.

How do I know when it’s time to install a water filtration system?

If you notice unpleasant taste, odor, discoloration, or buildup on fixtures and glassware, or if you have an older home or well water, it’s a good idea to have your water tested. Even municipal water can contain chlorine, sediment, and trace impurities that affect not only your drinking water but also your skin and hair. Many families find that a treatment system helps reduce dryness, irritation, and mineral buildup, creating a cleaner, more comfortable experience throughout the home.

How do I test my water to know what system I need?

We offer on-site water testing to identify contaminants, hardness, pH, and more. This ensures we recommend the right system for your specific home rather than a one-size-fits-all solution.

Is a home filtration system still necessary if my city already treats the water?

Yes. Municipal treatment removes bacteria and large contaminants but often leaves chlorine, sediment, and trace chemicals behind. Once water leaves the treatment plant, it is no longer treated or monitored as it travels through miles of pipes and aging infrastructure before reaching your home. A home filtration system ensures the water you use every day is as clean and consistent as possible.

What is the lifespan of a whole-house filtration system?

The tanks can last 10 to 20 years or longer, depending on the system and how well it is maintained. Filter media and cartridges do need periodic replacement, but the main unit itself is a long-term investment in your home. Most of our whole home water treatment systems include a 10-year tank warranty and a 5-year head warranty.

What should I look for when choosing a filtration system?

Look for NSF-certified systems, strong warranties, professional installation, and a provider who offers maintenance and support. Quality and proper sizing matter more than brand name alone.

What are common problems with filtration systems?

Clogged filters, reduced water flow, or mineral buildup can occur over time if filters aren’t changed regularly. With professional installation and maintenance, these issues are rare and easily prevented.

Do I need a UV system if I’m on city water?

Most city-water homes don’t require a UV system for everyday use because municipal water is already treated for bacteria. However, it’s important to know that traditional filtration systems alone do not protect your home during a boil-water advisory. Filters like carbon, sediment, or even whole-house systems can’t neutralize bacteria or microorganisms.

A UV system is the only add-on that provides that extra layer of protection by disinfecting water as it enters your home.


So while UV isn’t always necessary, many homeowners choose it for peace of mind, especially if they’ve experienced boil-water notices in the past or want the highest level of protection.
