Tip 1: Swap Out the Angle Stops


The small valves located beneath your sinks and toilets are critical for shutting off the water during an emergency. Reusing old, crusty valves during a remodel is a massive mistake because the internal rubber seals are likely dry rotted.


  • Ditch the Multi Turn Valves: Replace the old hardware with modern quarter turn ball valves that easily glide open and closed without sticking.
  • Inspect the Copper Stub: Have your plumber clean and inspect the copper pipe sticking out of the wall to ensure it is not pitted with corrosion before attaching the new valve.
  • Color Match the Hardware: Select new shutoff valves that match the finish of your new faucet to create a clean, cohesive look inside your custom vanity.


Tip 2: Upgrade to Braided Steel Supply Lines


The flexible hoses connecting your shutoff valves to your new faucet take a lot of daily water pressure. Cheap plastic or thin rubber lines eventually bulge and burst, flooding your brand new kitchen floor.


  • Choose Stainless Steel: Always insist on stainless steel braided supply hoses that are incredibly resistant to bursting and rodent damage.
  • Measure the Slack: Ensure the new lines are the correct length, as overly tight lines strain the connections and excessively long lines can kink and block the water flow.
  • Check the Gaskets: Verify that the rubber gaskets inside the hose fittings are perfectly seated before tightening them onto the new fixtures.


This careful attention to connecting new hardware properly is something clients notice firsthand during high end remodeling projects.


► Client Experience: Keri Nelson shared "Most recently, he worked at my personal residence helping me connect my new farmhouse sink, faucet and cup washer. John is my go to plumber. Always professional, on time, and very fair. John goes the extra mile to make sure connections are done right and with quality materials."


Going the extra mile to ensure farmhouse sinks and custom fixtures are installed perfectly is exactly why Keri Nelson trusts our craftsmanship.


Tip 3: Install a Pressure Balancing Shower Valve


If you are tearing out the tile in your bathroom, you must replace the old shower valve hidden behind the wall. Older valves allow the shower temperature to spike dangerously high if someone flushes a nearby toilet.


  • Protect Against Scalding: A pressure balancing cartridge automatically adjusts the hot and cold water mix to prevent sudden temperature drops or scalding bursts.
  • Secure the Valve Body: Ask the technician to securely strap the brass valve body to the wooden studs so your new shower handle does not wobble when you turn it.
  • Check for Proper Depth: The valve must be set at the exact right depth in the wall so the decorative trim plate sits perfectly flush against your new shower tile.


Tip 4: Replace the P-Trap Assembly


The curved plastic or metal pipe under your sink holds a small amount of water to block sewer gases from entering your home. Reusing a dirty, brittle trap guarantees annoying drips inside your new cabinets.


  • Use Durable PVC: Swap out flimsy, paper thin plastic traps for thick, schedule forty PVC piping that resists impact and chemical wear.
  • Hand Tighten the Slip Joints: Plumbers carefully hand tighten the slip joint nuts to avoid cracking the plastic threads, ensuring a totally watertight seal.
  • Align the Drain Tailpiece: The new trap must align perfectly straight with the sink drain tailpiece to prevent the rubber slip washers from sitting crooked and leaking.


Tip 5: Secure the Fixture Mounting Brackets


A heavy new faucet or a deep basin sink requires solid mounting hardware to prevent shifting over time. A wobbly fixture eventually breaks the watertight silicone seal around the countertop.


  • Reinforce the Sink Deck: Heavy farmhouse sinks require sturdy wooden support bracing built directly into the base cabinet to handle the immense weight when filled with water.
  • Use the Proper Putty: Plumbers use specialized plumbers putty or waterproof silicone to seal the drain flange securely against the sink basin.
  • Tighten the Faucet Nuts: The mounting nuts holding the faucet to the countertop must be tightened with a specialized basin wrench to prevent the spout from rotating during daily use.


Frequently Asked Questions


Do I need a permit to replace a shower valve?


Yes, any time a plumber cuts into the water lines behind the wall and solders in a new shower valve, local building codes require a permit. A city inspector must verify that the new valve features anti scald protection and is properly secured to the framing before you close up the wall with cement board and tile.


Why should I hire a professional to install a kitchen faucet?


Modern kitchen faucets feature complex pull down sprayers and integrated supply lines that must be routed perfectly to avoid tangling. A professional plumber ensures the hot and cold connections are correct, the mounting hardware is rock solid, and the drain assembly is completely leak free. Attempting to install it yourself often results in stripped threads and slow drips that ruin expensive custom cabinetry.
