Replacing a standard toilet with an elongated one is straightforward. The two types can be installed using the same existing drainpipe and plumbing. If you have a small bathroom, make sure that an elongated toilet doesn’t violate local building codes for clearance, which is the space between fixtures and walls. 

Toilet augers are hand-held drain snakes. Most of them come with 3 to 6 feet of cleaning cable and a curved, plastic elbow sleeve to protect your toilet bowl. If your clog does not go beyond the toilet’s wax seal, a 3-foot auger would be sufficient. Otherwise, you may need a 6-foot auger to unclog the drain.

The water in your toilet tank refills after each flush. So if you see dirty water in the bowl, you should check the tank to see if it’s coming from there. A dirty toilet tank can be the result of sediment in the water itself—-after all, the water will sit in the tank between flushes and can cause the interior to change into a dingy color. Faulty toilet components, like an old flapper, corroded tank lever or chain, or damaged seals, can also lead to dirty water as the materials break down inside the tank. You can clean the toilet tank or change out the old parts to give it a fresh start.

No, you can’t convert a gravity-flush toilet to a pressure-assist toilet. Pressure-assist toilets include a tank-within-the-tank, and a standard gravity-flush toilet doesn’t have a capability to include the additional tank. If you want the benefits of a pressure-assist toilet, you’ll have to make the investment in a new one.
