Overview
What needs fixing — and what's worth replacing
Toilets are simple machines that fail in predictable ways. A running toilet is almost always a flapper or fill valve. A weak flush is usually a clog or low water level. A leak at the base is a wax seal or a cracked flange. A leak between tank and bowl is the tank-to-bowl gasket. Most toilet repairs are $89-$385 and done in 30-90 minutes.
When the whole toilet needs to go — cracked porcelain, internal corrosion, or you're upgrading to a smart bidet seat or one-piece comfort-height — replacement is $385-$865 plus the toilet itself. Lehi's tech-family demographic loves smart toilets (Toto Washlet, Kohler Numi, Brondell) and we install them often, including the electrical and water hookups.
Common Lehi toilet calls
- Running toilet — flapper failed, fill valve worn, or chain caught. $89-$185 fix

- Leak at the base — wax seal failed or flange cracked. $185-$385
- Leak between tank and bowl — tank-to-bowl gasket. $145-$245
- Toilet won't stop running — fill valve replacement, $145-$245
- Cracked tank or bowl — replacement only, no repair option
- Phantom flushing — flapper not sealing, $89-$145
- Toilet replacement — full swap including flange repair if needed, $385-$865 labor + toilet
- Smart bidet seat install — Toto Washlet, Brondell, Kohler Numi — electrical and water hookup, $245-$485 + seat

Hard-water specifics for Lehi
Lehi's hard water leaves calcium scale on the under-rim jet holes that distribute flush water. Over 5-10 years, half the jet holes get plugged and the flush gets weak. We clean the jets manually as part of any toilet service call, but a softener install is the long-term fix that keeps every toilet flushing strong for the toilet's full life.
Mineral buildup on the inside of the tank also gunks up flappers and fill valves. Soft water cuts the failure rate of these parts roughly in half.
What we install for upgrades
Toto — best-in-class flush technology, common upgrade in Traverse Mountain primary suites. Drake, Aquia, Vespin, Neorest series.
Kohler — solid mid-to-high range, good aesthetics. Memoirs, Cimarron, San Souci.
American Standard — workhorse residential, great value. Champion 4 series flushes a tennis ball.
Smart bidets — Toto Washlet (most common), Brondell Swash, Kohler Numi, Bemis. Heated seat, warm water bidet, dryer, deodorizer. Lehi's tech-family households install these regularly.
Wall-hung toilets — luxury Traverse Mountain primary baths. In-wall carrier system, hidden tank. We install but always recommend doing it during a remodel rather than retrofit.

The Process
How a Lehi Toilet Service Call Runs
On the truck
Cable machine, jetter, and pipe camera — every call.
Diagnosis
Tech identifies the failure mode (running, leaking, weak flush, cracked) and gives you a flat-rate repair quote. If replacement makes more sense, you get both quotes side-by-side.
Common repair stock on truck
Flappers, fill valves, supply lines, wax seals, tank-to-bowl gaskets — all stocked. Most repairs done in one visit, 30-90 minutes.
Replacement install
Old toilet removed and hauled off. New flange installed if needed (sunken or cracked flanges common in older Lehi homes). New wax or rubber seal. Toilet set, leveled, supply line connected, tank filled, flush-tested.
Smart bidet hookup (if applicable)
Hot water tap off under-sink supply, T-valve at toilet for cold supply, GFCI electrical outlet if needed. Most smart bidets need 120V power — we run from nearest outlet or call our electrician partner if a new outlet is needed.
Final test and cleanup
Flush 3-5 times, check for leaks at flange, supply, tank-to-bowl. Clean work area. Walk you through the new toilet's features. Quality Service Club members get the calcium jet cleaning at no charge during the visit.
