Plumbing vent pipes are a crucial part of your plumbing. They run up from kitchens and bathrooms and are liable for carrying sewer gases out of your home to stay you from getting sick. In order for it to work, the vents must be above the plumbing fixtures so that they don't fill with water. Also, the gases that escape the vents stink. Placing the vents on your roof, leave the smelly gases to flee your home while keeping the vent pipes from filling with water.
Aside from the rubber boot cracking or loosening over time, the vent pipe can become clogged. If this happens, the gases may become trapped inside your home. It’s important to examine your vent pipes to ensure they stay beyond leaves, debris, or animals. Your boots can also need attention.
Rubber roof boots surround your plumbing vent pipes. they will deteriorate when exposed to the sun and high temperatures causing them to crack and leave a niche where water can enter the house. Once the boot cracks, water can enter your home by following the vent PVC pipe down. If this happens, ceiling damage is the most likely result and mold can also occur.
Why Plumbing Air Vents Are Important
Your home’s plumbing helps to remove water and waste. Its drainage and vent functions are two systems that employment together. Drainage pipes carry waste out of your home to either the town sewer or a tank. Vent pipes supply fresh air to every fixture within the house, which helps the system move water through the drainage pipes whenever a restroom is flushed or a sink is drained.
Plumbing air vents also prevent sewer gases from entering the house and permit wastewater gas and odor to flee. Plumbing vent pipes are located on roofs, far away from windows or air-con units, in order that the fumes can dissipate.
Unfortunately, the lifespan of your roof is usually longer than that of your roof boots. The neoprene rubber components tend to weather and crack around the 7-year mark, give or take, depending on the exposure your roof has to direct heat and UV rays. Your shingles may be fine but your roof may still be at risk for developing leaks.
Most residential roofs have between 2 and 4 vent pipes with rubber boots. If one boot cracks, it’s wise to consider replacing all of them while you have a contractor on-hand.
When a plumbing vent pipe is blocked, negative pressure builds up in drainage pipes and water flow is interrupted. Though you may have success clearing a clogged drain yourself, stoppages will continue to occur if a blocked vent is the culprit.
Ongoing stoppages and slow-flowing drains can lead to sediment forming inside the drain pipes. This can further damage your plumbing system and may result in hefty pipe repair or replacement costs down the road.
The best way to be sure your roof boots and pipe vents are clear and functional is to have them inspected by a certified roofing inspector.
