Removing and replacing a damaged or leaky bathtub drain in a standard site-built home is usually a straightforward task. But for manufactured or mobile homes with a different setup and configuration, it’s a different story.
But don’t worry, it’s not rocket science.
All you need to do first is understand what is different from what you’ve known before learning how to replace a bathtub drain in a mobile home.
The differences in bathtub drain between mobile and site-built homes
In a typical drain assembly of standard site-built homes, there is a threaded insert where people use a nut to mount the drain from below.
On the other hand, mobile homes use the “garden” style instead.
In this type of tub, there is no overflow tube, and you must use the included nut and seal to tighten the drain to the bathtub. Most of them come with a drain fitting that you can remove from the tub. You can replace this fitting by securing the retaining nut at the bottom of the tub.
What you need
- A new drain, pipes, and drain fitting
- A Dumbbell wrench
- Plumber’s putty
- A hacksaw blade (optional)
How to replace a bathtub drain in a mobile home
Get the Dumbbell wrench – a type of wrench used for removing bathtub drains, kitchen sink baskets, and closet spuds – and open the drain fitting. It can help prevent scratches in the decorative finishes of your bathtub.
Remember to lever it against the fitting’s crosshairs. If the fitting gets stuck, cut it away with a hacksaw blade.
Be careful with the depth of your cut.
Don’t let it reach the tub – you just need it to be deep enough to cut through the rim and the threads. Make another cut that is 0.5-in away from your first cut.
Use a flat screwdriver to extract the cut segment, and then pry open the drain fitting up before unscrewing it counterclockwise.
Make sure that the drain pipes and drain fitting are ready for installation.
Find and loosen the drain trap, which is secured under the tub by a nut. Move the pipes and trap away to provide space for the new drain.
Now go to the top of your bathtub. Position the plumber’s putty around the new fitting and push it to your tub’s drain opening.
Move back to the bottom of your tub to push the seal and the retaining nut to the end of the new fitting.
Tighten the nut on the drain fitting until it is securely in place. If you find it spinning instead, you may need a helper to hold the fitting from above when you screw it.
Install all the drain pieces to this new fitting. This may require you additional fittings and pipes to finish the installation of the connection. Use pipe pieces and trap with the same diameter whenever possible, which will help your bathtub drain water faster.
Make sure that the trap nut has been tightened. Fill the tub with water and drain it to see if there are any leaks.
