Toilet Installation & Repair FAQ
How long does toilet installation take?
A straightforward toilet replacement takes about an hour in a Southern NH home. If the flange needs repair or there is subfloor damage, it may take longer.
My toilet is running constantly, what's wrong?
Usually a worn flapper, a faulty fill valve, or a float set too high. All are inexpensive repairs. A running toilet can waste 200 or more gallons per day, so it is worth fixing promptly.
Can you install a bidet toilet seat?
Yes. Most bidet seats require a nearby GFCI outlet in addition to the supply line connection. A.J. LeBlanc Heating handles both across Southern NH.
Should I repair or replace my toilet?
If the toilet is over 15 to 20 years old or has a cracked tank or bowl, replacement is usually more cost-effective. For newer toilets with minor issues, repair makes sense.
