Toto Construction in Irvine, CA | Sawyer Remodeling
We’re Sawyer Remodeling, an Irvine General Contractor providing independent Toto sales, installation, and repair across the city. We’re not factory-authorized, and we don’t pretend to be. What we are is a local crew that has pulled apart hundreds of Toto Drake toilets, Ultramax II bowls, and Washlet bidet seats in Irvine homes, and we know which failures show up here more than anywhere else. Hard Irvine water changes how Toto valves behave. Older Villages of Irvine homes have flange issues you won’t find in newer developments. Our Toto work is priced in writing before we touch a single tool. Call (254) 272-5876 for an estimate.
Why Irvine Residents Choose Us for Toto Service
Luca Romano has been swinging tools in Southern California for over two decades, and he grew up watching his uncle gut and rebuild a Silver Lake duplex one weekend at a time. That kind of hands-on learning sticks. When our crew opens up a Toto toilet in Irvine, we know what we’re looking at before the tank lid comes off. We stock genuine Toto OEM fill valves, 3-inch flappers, and tank-to-bowl gaskets for the Drake and Ultramax lines, because those are the parts that fail first in Orange County water. Our technicians are background-checked and uniformed, so you know exactly who’s walking through your door. Every project runs under The Relay Visibility Guarantee: a live arrival time, photo updates before and after, and a written price that doesn’t change.

Common Toto Construction Problems We Solve in Irvine
- Ghost running in Toto Drake toilets. Irvine’s municipal water carries enough mineral content to coat the ceramic flush valve and fill valve with scale. The toilet runs randomly for five seconds, then stops. A generic flapper won’t fix it because the issue sits deeper in the valve body. We disassemble the assembly, descale it, and replace the OEM flapper and fill valve when needed.
- Cracked closet flanges under one-piece Toto toilets. 1970s and 1980s Villages of Irvine homes often still have their original builder-grade closet flanges. They were fine for a standard toilet, but add a Toto Washlet seat and the load shifts. We’ve seen hairline cracks that let water seep slowly onto the tile. This needs a flange repair ring or full replacement before the fixture will hold.
- Washlet seat hinges seizing in Irvine’s dry inland heat. Toto Washlet S550e and S7A seats have plastic hinge assemblies that swell and crack when exposed to repeated hot, dry conditions combined with hard-water film. The seat won’t stay mounted, or the wand clicks and jams mid-cycle. We replace the hinge assembly and descale the wand nozzles with Toto-compatible cleaning solution.
- Dual-flush assemblies failing early. Toto’s proprietary dual-flush mechanisms wear faster than the rest of the toilet because they cycle more often. When a homeowner drops in a cheap aftermarket unit from a big-box store, the seals don’t sit right and the toilet leaks at the tank bolts. We use OEM Toto flush assemblies, and the difference in fit is immediate.
- GFCI trips on Washlet seats in older Irvine ADUs. Detached ADUs and garage bathrooms built before current electrical codes often share a circuit with other outlets. A Toto Washlet draws more current than a standard outlet expects, and the GFCI trips repeatedly. We verify the branch circuit, add a dedicated outlet where code requires it, and mount the seat properly.
Toto Service in Irvine: What Local Conditions Mean for Your Equipment
Here’s what you won’t read on a generic Toto site. Irvine homes built in the 1970s and early 1980s, especially through the Villages of Irvine, were plumbed with closet flanges designed for toilets that weighed about half what a modern one-piece Toto weighs. Pair that original flange with thirty years of hard-water mineral creep, and the plastic ring becomes brittle. Add a Washlet S550e with its internal heating element and water reservoir, and you’ve added another 15 to 20 pounds sitting directly on that old flange. We regularly find that installing a Toto Washlet in these Irvine bathrooms requires reinforcing the flange with a stainless steel repair ring and replacing the angle stop before the bidet seat will function without leaking at the base. In a 1978 Woodbridge townhome off Springbrook North, our crew pulled a customer’s original Toto one-piece toilet to find a hairline crack in the closet flange caused by decades of hard-water mineral creep. We rebuilt the flange with a repair ring, reset a new Toto Drake CST744 with a fresh OEM fill valve and wax ring, and mounted the homeowner’s Toto Washlet S550e on a reinforced outlet. The result matched the original tile layout and has held up since. That’s what local Toto work looks like in Irvine.
Toto Models & Products We Service in Irvine
We work on the Toto Drake CST744 series, the Ultramax II MS604 line, Toto Washlet S550e and S7A bidet seats, and Toto EcoPower and Standard commercial flush valves. Our parts approach is simple: when the model is still supported, we install genuine Toto OEM fill valves, flappers, tank gaskets, and flush assemblies. For discontinued lines like pre-2010 EcoPower, we source high-quality aftermarket components that match the original spec. We keep the common failure parts stocked in our service vehicles so Irvine homeowners aren’t waiting on a parts shipment. When a Toto toilet or Washlet needs a $400-plus control board or the bowl itself has cracked, we’ll tell you straight: replacement with a current Drake or Ultramax costs less than chasing a discontinued unit. You can see our full remodel scope on the Irvine service area page.

FAQs – Toto Construction in Irvine
The flapper is sitting on a valve body coated with mineral scale from Irvine’s hard water, so it never seals completely. You can swap flappers all day and the ghost running continues. The fix is to descale the flush valve seat and install an OEM Toto flapper sized for the CST744 series, not a universal one. Call (254) 272-5876 and we’ll do it right the first time.
Yes, in most cases. The real question is whether your closet flange and electrical outlet can support it. In older Villages of Irvine homes, we often reinforce the flange and run a dedicated GFCI outlet before mounting a Washlet S550e or S7A. The toilet itself may not need replacement at all. We assess that during the free estimate.
If it needs a control board, replacement almost always wins. A new Toto Drake G or Ultramax II costs less over five years than nursing a pre-2010 EcoPower back to health, especially when the parts are no longer manufactured. If it’s a simple fill valve or flush assembly, we’ll repair it. We’ll give you the numbers either way before you spend a dollar.
We install the Toto Drake CST744, the Ultramax II MS604, and other current Toto models regularly. We keep common OEM parts stocked in our vehicles for fast Irvine turnaround. If you’re remodeling a bathroom around a specific Toto model, we’ll order it directly and have it staged before demo starts. Call (254) 272-5876 for model-specific pricing.
It shortens the life of the internal components that touch water, yes. Hard mineral deposits build up on the fill valve, the flush valve, and the Washlet wand nozzles. The seat electronics usually survive fine. What we see most in Irvine is that the hinge assemblies and wand mechanisms fail first due to combined heat and scale. Regular descaling extends the seat’s usable life by years.
