The biggest sign that your flange leaks is if you notice water at the base of the toilet. The cause is likely due to a poor flange installation, so you might have issues with loose bolts, an uneven flange, or a cracked plastic flange. Add a deteriorating wax seal to this, and you have a recipe for disaster. The best solution is to shut off the water valve, replace the toilet flange, and seal it with a new wax ring.

Yes, you can install a farmhouse sink on an existing countertop—but there are some caveats. You’ll need to precisely measure. It’s best to choose a sink that’s the same dimensions as your existing sink, since your contractor won’t have to cut the countertop. Otherwise, pay close attention to the depth of your counter (the front to back measurement). You don’t want to install something that’s so big it sticks out beyond your countertop and cabinetry.

Leaks, clogged drains, cracked basins, and worn-out seals are common problems that may require professional repair.

The time it takes to install a sink depends on whether you hire a professional or do it yourself, as well as the complexity of the job. A professional plumber can typically install a sink in 1 to 4 hours, with most routine jobs taking around 1 to 2 hours. However, more complicated installations will take longer. Projects that involve rerouting plumbing, installing an under-mount sink, or making countertop modifications can take a full day. Installing a sink with a prefab vanity could also stretch the project to 6 to 8 hours. If you plan to install the sink yourself, you should set aside 4 to 6 hours, though it could take longer. It's also recommended to have a friend help, especially if you are working with a heavy sink made of a material like porcelain.
