Late Sunday night we had an emergency leak, where we were forced to shut off water to entire house. I reach out MT Dunn plumbing and in a short notice and within 35 mins Irich was able to come over and fixed our leak. Truly appreciate the quick response especially being late Sunday night around 9-10pm!!!

We inadvertently discovered our kitchen and washing machine drains were disconnected and dumping water underneath the house, in the crawlspace. We may never know why or for how long but Irich responded to my call personally and set a date within a single business day knowing we'd couldn't use the kitchen until it was fixed. He was here on time and had it repaired in a half day. Proper invoicing and estimates based on labor and parts always makes me happy. So glad to have a plumber now. I won't go anywhere else.

Irich is very easy to work with and always shows up on time. He’s honest, professional, and very efficient. His work is fast but never rushed. He does things the right way and never cuts corners. Over the past three years, he has helped us three times: installing a water heater, replacing some toilet parts, and installing a new toilet. Every job was done quickly and professionally. He’s also very respectful of our home and keeps things clean while working. On top of that, he’s a genuinely kind person—even great with our dog 🐶 His pricing is fair and he never overcharges. It’s hard to find someone this trustworthy. I highly recommend him. Thank you Irich!

I've had MT Dunn plumbing handle a couple of plumbing issues we've had over the last few years. Our most recent visit was due to a leaking valve going to our guest bathroom toilet. It was stripped and Irich was able to fix it in short order. Friendly, transparent, punctual, and knowledgeable. We highly recommend Dunn plumbing and Mikes son Irich.

This is the second time I’ve used M T Dunn Plumbing and both experiences have been great. I recently discovered I had a leaky pipe underneath my cement driveway. M T Dunn came out and assessed the situation and gave me multiple ways get it fixed with varying costs. I decided what I wanted to do and they came out a few days later and took care of it. They cut a hole in the cement, found the leak, fixed it and patched the driveway in a single day which will end up saving me a ton of money. They’re very fair and have gotten things done quickly and easily both times I’ve needed them.

How Does MT Dunn Plumbing Install a New Toilet?

A careful, methodical process ensures your new toilet is set correctly and performs the way it should from day one.

1

Initial Consultation and Toilet Selection

Technicians discuss your bathroom’s needs, water efficiency goals, and preferred height or style before confirming the right toilet model.

2

Shutting Off Water Supply

The water supply valve is shut off and the tank and bowl are drained completely before any removal work begins.

3

Removing the Old Toilet

The old unit is disconnected, unbolted, and carefully removed without damaging surrounding flooring or fixtures.

4

Inspecting the Flange and Subfloor

The closet flange is checked for cracks, corrosion, or improper height, and the subfloor is inspected for water damage or soft spots.

5

Repairing or Adjusting the Flange if Needed

If the flange is damaged, worn, or sitting at the wrong height, it’s repaired or shimmed before installation continues.

6

Setting the New Wax Ring or Seal

A fresh wax ring or approved sealing gasket is placed to ensure a watertight connection between the toilet base and drain.

7

Positioning and Leveling the Toilet

The toilet bowl is carefully set onto the flange, checked for level, and adjusted as needed to prevent rocking.

8

Securing the Toilet to the Floor

Closet bolts are tightened evenly and to proper torque, securing the toilet firmly without over-tightening and cracking the porcelain.

9

Installing the Tank and Connecting Water Supply

The tank is attached, the supply line is connected, and water is turned back on to begin filling the tank.

10

Testing Flush Performance and Checking for Leaks

The toilet is flushed multiple times to confirm proper flush strength, and all connections are checked closely for any sign of leaking.

11

Caulking and Final Walkthrough

The base is caulked for a clean, finished look, and technicians walk you through proper use and care for your new toilet.

Most standard toilet installations are completed within one to two hours, including removal of the old unit.

When Should You Call MT Dunn Plumbing for Toilet Installation?

There are several clear signs it’s time for a new toilet rather than another repair. Call us if:

What Should You Consider Before Installing a New Toilet?

A few key factors make a real difference in comfort, performance, and long-term reliability.

  • Bowl Height: Standard height suits most households, while comfort height suits taller users or those with mobility needs.
  • Flush Type: Gravity-fed models are quieter, while pressure-assisted models offer stronger flush performance.
  • Water Efficiency: Modern low-flow models can use significantly less water per flush than older units.
  • Rough-In Size: The distance from the wall to the drain must match your new toilet to avoid installation issues.
  • Bowl Shape: Elongated bowls offer more comfort, while round bowls suit smaller bathroom layouts.
  • Seat and Lid Features: Soft-close lids and easy-clean finishes add convenience for everyday use.
  • Existing Flange Condition: An older or damaged flange may need repair before a new toilet can be properly secured.

Should You Install a New Toilet or Repair Your Existing One?

From what we’ve seen, the answer depends on your toilet’s age, overall condition, and whether the problem is a simple repair or a sign of ongoing wear. At MT Dunn Plumbing, we help homeowners choose the option that provides the best long-term value instead of the quickest short-term fix.

Here's why we feel so strongly about this:

Many toilet problems can be repaired quickly and affordably, but not every toilet is worth repairing. A relatively new toilet with a faulty fill valve, worn flapper, or leaking seal can often be restored without replacing the entire fixture. These repairs are cost-effective and usually return the toilet to reliable operation for years to come.

We’ve also seen homeowners continue repairing older toilets that have become inefficient or require frequent service. Once a toilet reaches ten to fifteen years of age, repeated repairs, higher water usage, and worn internal components often make replacement the more practical investment. If the porcelain is cracked, replacement isn’t just recommended, it’s the only safe solution.

Our opinion is simple: continuing to repair a toilet that's nearing the end of its lifespan is an expense we wouldn't recommend to anyone.

The cost of installing a new toilet is often outweighed by improved reliability, lower water consumption, and fewer repair calls in the future. We think of it as investing in a fixture that performs better, saves water, and gives you greater peace of mind every day.

Older, inefficient toilets deserve especially careful evaluation. Aging components, hidden leaks, and outdated flushing technology are common issues that can increase water bills and lead to recurring plumbing problems.

Bottom line from our team:

If you’re serious about making the right long-term investment, we’ll inspect your existing toilet, explain the pros and cons of repair versus replacement, and help you choose the solution that best fits your bathroom, your budget, and your household’s needs.
