Home inspections often reveal various plumbing issues that can range from minor annoyances to serious concerns. Here are some common plumbing problems found during inspections and their implications:
Minor Leaks Around Under-Sink Plumbing
Leaks around sink waste and supply lines are frequent issues in home inspections. These leaks often occur because kitchen and bathroom sinks are commonly updated or modified during renovations. Even though these leaks are relatively easy to fix and prevent with proper installation, they can lead to significant water damage if they go unnoticed for long periods.
**Tip:**
Regularly check under your sinks for leaks, especially after renovations. Addressing these leaks promptly can prevent more severe damage.
Thermal Expansion Protection Devices for Water Heaters
Proper protection against thermal expansion is crucial for the safe operation of water heaters. There are two main types of protection:
1. Temperature Pressure Relief Valve (TPRV)
The TPRV is a critical component of your water heater. It’s a small valve, often found on the side or top of the tank, with a drain tube leading to the safety pan. This valve opens to release excess pressure and prevent potential damage to the water heater. If you notice dripping from this valve, it indicates that it’s functioning to relieve excessive pressure.
2. Thermal Expansion Tank
A thermal expansion tank is a metal tank, usually the size of a basketball, located near the water heater. It contains a rubber bladder that expands to accommodate the increased pressure caused by thermal expansion. This is especially important in homes with backflow prevention devices.
Inaccessible Main Water Shutoff Valve
The main water shutoff valve is essential for stopping all water flow into the home in case of a leak or emergency. While not technically a defect, its accessibility can be a significant issue. In newer homes, this valve is typically located in an accessible area, such as near the water heater, in a utility closet, or in the garage. However, in older homes, especially mid-century ranch homes, it might be placed in difficult-to-reach areas like deep crawlspaces.
**Tip:**
Know the location of your main water shutoff valve and ensure it’s easily accessible. If it’s in a hard-to-reach spot, consider relocating it to a more convenient location.
Addressing these common plumbing issues can help maintain the integrity of your home’s plumbing system and prevent more severe problems down the line. Regular inspections and maintenance are key to ensuring your plumbing remains in good working order.
