Frequently asked questions
Plumbing, Plainly Answered.
Questions homeowners ask, grouped by topic.
General
What kinds of homes does Prestige Plumbing work in?
Prestige is residential only, and it works in homes of every kind — ranches, colonials, condos, older bungalows and newer builds alike. Whatever the house, the visit is the same: careful, clearly explained, and finished with the room as it was found.
Is a small repair worth calling about?
Yes. A dripping faucet, a running toilet, a slow drain or a water heater that has quit is as welcome as a remodel or a repipe. Everyday repairs and routine maintenance are a large part of residential plumbing, and they get the same planned, careful visit as a larger project.
What happens during the first visit?
We listen to what has been happening, inspect the affected fixtures or system, and explain what we find before any work begins. If more than one approach is reasonable, you will hear each one and what it involves.
Will you protect floors and finishes while you work?
Yes. Protection goes down before tools come out — floor runners, drop cloths and covers for nearby surfaces — and the work area is cleaned before we leave.
Can I request a specific time for the visit?
Visits are arranged around an arrival window agreed in advance. Tell us what suits the household when you request service, and we will confirm what is available.
Which communities do you serve?
Prestige serves residential homes across Metro Detroit, with a focus on Bloomfield Hills, Birmingham, Franklin, West Bloomfield, Orchard Lake Village and the Grosse Pointes. If your community is not listed, ask — the service area is confirmed when you request a visit.
Plumbing Repair
Why does my toilet run for a few seconds by itself every so often?
That brief refill, sometimes called phantom flushing, usually means water is slowly leaking from the tank into the bowl, most often past a worn flapper or a misaligned seal. The fill valve tops the tank back up when the level drops. It wastes water quietly and is generally a straightforward repair, though on some toilets the flush valve itself, rather than the flapper, is the part that needs replacing.
Is it worth fixing a slow drip, or can it wait?
A drip at a faucet spout is rarely urgent, but it rarely improves. Over time it can etch stone, stain finishes and wear the valve seat further, which can turn a cartridge replacement into a larger repair. A drip from a supply connection or valve body under a sink is different: it can damage cabinetry unseen, and it is worth having looked at promptly.
Water Heater Installation & Replacement
How long should a tank water heater last?
Tank water heaters commonly last somewhere around 8 to 12 years, though that range varies widely with water quality, sediment, how hard the heater works and whether it has been maintained. The anode rod, which corrodes so the tank lining does not, plays a large part. A heater with a spent anode and years of sediment can fail well before that range; one that has been looked after may outlast it.
What is the temperature and pressure relief valve, and should I test it?
The T&P relief valve is a safety device that opens if the water in the tank becomes too hot or the pressure too high, releasing it through a discharge pipe rather than letting the tank fail. It should never be capped or plugged.
Testing it by lifting the lever is commonly recommended, but an older valve may not reseal afterward. If yours has not been touched in years, it is reasonable to have it checked during a service visit.
Tankless Water Heaters
Will a tankless heater give us unlimited hot water?
It will keep producing hot water as long as the demand stays within its capacity, so it will not run out the way a tank does. What it cannot do is supply more flow than it is sized for. If several showers, a tub and the dishwasher run at once in January, a single unit may not keep up, and the water will cool or flow will drop. Sizing to realistic winter demand is what prevents that.
Why does a tankless heater need descaling?
As water is heated, minerals such as calcium come out of solution and deposit on the hottest surfaces, which in a tankless heater means the narrow passages of the heat exchanger. Over time scale reduces heat transfer and can trigger error codes or overheating. Descaling circulates a mild solution through the unit via its service valves. How often it is needed depends largely on water hardness and usage.
Drain & Sewer Services
Are chemical drain cleaners safe to use?
They are best avoided. Caustic drain openers can generate heat and react with older metal pipe, damage some finishes if they splash, and often only partially clear a blockage, leaving harsh chemicals sitting in the trap for whoever opens it next. For a recurring slow drain, mechanical cleaning of the trap or line removes the material rather than burning a hole through it.
Why does water come up in the basement floor drain?
The floor drain is usually the lowest opening on the building drain, so when the main line is restricted, water from fixtures above has nowhere to go and rises there first. It is a strong indication that the blockage is in the main line or lateral, rather than in an individual fixture. Stopping use of water upstairs until the line is cleared limits the amount that backs up.
Fixture Installation
Can you install fixtures we have purchased ourselves?
Yes, and that is a common arrangement: many homeowners pick out a faucet, toilet or shower trim at a store or showroom, or through a designer, and the plumber installs it. It helps to share the model numbers and specification sheets before the visit, so compatibility with existing valves and rough-in can be confirmed and any additional parts identified. We will also inspect the pieces on arrival, before installation begins.
Why can’t I simply swap my shower handle for a new style?
The visible handle and trim connect to a valve body inside the wall, and most trims are designed for one specific valve. A trim from another line generally will not engage the cartridge or seal properly against the wall. If you want a different look without opening the wall, the options are usually trims made for your existing valve. A different style altogether usually means replacing the valve.
Sump Pumps
How often should a sump pump be tested?
A simple test, slowly pouring a bucket of water into the basin until the pump starts and empties it, is worth doing a few times a year and particularly ahead of the wetter spring months. Watch that the float rises freely, the pump starts promptly and shuts off cleanly. If the pump hums without moving water, or fails to start, that is the time to have it looked at.
Do we really need a battery backup pump?
Heavy storms and power outages often arrive together, which is precisely when a primary pump is most needed and least able to run. A battery backup provides a second line of defense against both power loss and primary pump failure. Whether it is worth it depends on how often your pump runs, how the lower level is finished and what is stored there. For a finished lower level, many homeowners decide it is.
Residential Repiping
How do I know if my home has polybutylene pipe?
Polybutylene supply pipe is usually gray, sometimes blue or black, and flexible, often stamped with PB2110 or a similar code. Look where the main water line enters the house, near the water heater and under sinks. Some homes have copper stubs coming out of walls, with polybutylene hidden behind them, so a visible stub alone does not rule it out. If you are unsure, it can be identified during a visit.
How disruptive is repiping a whole house?
It depends a great deal on the house. Homes with accessible basements, crawlspaces or attics may need relatively few wall openings; homes with finished lower levels or slab sections need more. Water is typically off during working hours on some days and restored overnight. The disruption is real, but with phased work, protection of finished rooms and clear scheduling, many households remain at home throughout.
