How to Stop a Tub from Slowly Draining While Plugged
Having a bathtub that slowly drains while it’s plugged can be a frustrating experience. Not only does it waste water, but it can also disrupt your daily routine. The good news is that there are several effective methods to stop a tub from slowly draining while plugged. In this article, we will explore these methods and provide you with step-by-step instructions to resolve the issue.
1. Check the drain stopper
The most common cause of a slowly draining tub is a faulty drain stopper. To check this, remove the stopper and inspect it for any debris or blockages. If you find any, clean the stopper thoroughly. If the stopper is damaged or worn out, it may need to be replaced.
2. Clear the drain trap
The drain trap is a U-shaped pipe that connects the bathtub drain to the main plumbing system. It’s designed to trap debris and prevent clogs. Over time, the drain trap can become clogged, causing the tub to drain slowly. To clear the drain trap, follow these steps:
– Remove the drain stopper.
– Use a plumber’s snake or a plunger to clear any blockages in the drain trap.
– Reattach the drain stopper.
3. Inspect the drain pipe
If the drain stopper and drain trap are clear, the issue may be with the drain pipe. Inspect the pipe for any signs of damage or blockages. If you find a clog, use a plumber’s snake to clear it. If the pipe is damaged, you may need to replace it.
4. Clean the vent pipe
A vent pipe allows air to enter the plumbing system, which helps prevent siphoning and ensures proper drainage. If the vent pipe is clogged, it can cause a slow drain. To clean the vent pipe, follow these steps:
– Locate the vent pipe on the roof or exterior wall of your home.
– Use a plumber’s snake to clear any blockages in the vent pipe.
5. Install an air admittance valve (AAV)
An air admittance valve is a device that allows air to enter the plumbing system without allowing water to siphon out. If you have a slow-draining tub, installing an AAV can help prevent the issue. Follow these steps to install an AAV:
– Purchase an AAV from a home improvement store.
– Locate the vent pipe near the bathtub.
– Cut the vent pipe and insert the AAV into the opening.
– Secure the AAV with the provided clips or screws.
By following these steps, you should be able to stop a tub from slowly draining while plugged. If the problem persists, it may be time to call a professional plumber for assistance.
