First, ensure the main water is shut off. Place a bucket under the existing angle stop to catch any remaining water. Disconnect the water supply line from the toilet and open the valve, allowing the water to drain completely into the bucket. Once drained, close the valve and place a rag on the floor to absorb any spills.

Goal: Safely drain residual water from the supply line.

  • Opening and closing the valve a few times can help ensure all the water is drained out.

FAQs

What are the most critical safety precautions I should take before and during bathtub removal?

Always shut off the main water supply to your home and drain the lines before beginning. Wear safety glasses (HDX Indoor Safety Glasses), heavy-duty gloves (Husky Large Heavy Duty Glove), and a respirator (3M P100 Household Respirator) to protect against dust, debris, and potential mold. Ensure the work area is well-ventilated, and if using power tools, keep cords away from water and work carefully.

Do I really need specialized tools like a tub drain wrench or a reciprocating saw, or can I get by with standard tools?

A tub drain wrench (like the Husky Double Ended Tub Drain Wrench) is highly recommended for efficiently removing the drain assembly without damaging the plumbing. While not always strictly necessary, a reciprocating saw with a demolition blade (like DIABLO Demo Demon) can significantly ease the removal of difficult tubs, especially heavy cast iron ones, by cutting them into manageable pieces. A pry bar (Stanley 12 in. Wonder Bar Pry Bar) is also essential for detaching the tub.

How long does a typical bathtub removal project take for an intermediate DIYer, and is it a one-person job?

For an intermediate DIYer, removing a bathtub typically takes 4-8 hours, depending on the tub type, access to plumbing, and unexpected issues. While some initial steps can be done solo, extracting the tub itself, especially if it's cast iron, often requires at least two people due to its weight and bulk to prevent injury or damage.

What are common pitfalls or mistakes to avoid when disconnecting plumbing or detaching the tub from the wall?

A common mistake is not completely shutting off the water or checking for remaining pressure before disconnecting pipes, leading to leaks. Another is forcefully prying without locating all securing points (like nailing flanges behind the surround), which can damage surrounding walls or the subfloor. Always double-check for hidden screws or mortar that might still be holding the tub in place.

In today's video we're going to be replacing this push on angle stop with a mel adapter and an FIP angle stop. I was already going to be replacing this toilet so when I noticed that they had this push to connect valve I went ahead and let the homeowner know that I would replace that for them as well. I personally do not like these types of fittings so whenever I see them I try to replace them. I'm sure the comment section though will let me know that I replaced a perfectly good fitting
