Bathrooms
- Check around the base of the toilet for signs of water damage (i.e.; rolled vinyl, black or white stains).
- To check for a "soft floor," stand straddled over the toilet and rock back and forth on each foot. If the floor feels spongy, it is probably rotting or weakened.
- Check to see how fast the toilet flushes.
- Check for leaky or loose tiles by pressing on the walls where they come in contact with the bathtub. If the walls are soft, water may have created damage behind the tiles.
Water Supply Piping
- Turn on water in bathtub and in the kitchen sink. If there is a noticeable reduction in water volume, the piping in the house may need to be replaced because of calcium and mineral deposits.
- If the home has a basement, check exposed piping for signs of leaking or recent repairs.
- Find the main line cleanout and ensure that it is accessible.
Water Heater
- Check the date of the water heater. The first four numbers of the serial number on the water heater are the month and year. Any heater over 15 years old is a candidate to be replaced.
- A rusty water tank is a sign of pending problems.
Miscellaneous
- Check to make sure that the garbage disposer and dishwasher connections are tight and leak free.
- Survey the inside of cabinets (with a flashlight) for signs of water damage, warped cabinet bottom or stains. Make sure that traps and supply tubes are not leaking.
- Check washing machine hoses for rupture. Turn valves on and off to test for leaks.
