Couple of Ideas for Plumbers Before Damaging Truss Joist for Bathtub Installation
Introduction
Installing a bathtub can be a straightforward process, but it can become complicated if the plumbing needs to be adjusted to fit the tub. In some cases, plumbers might cut into truss joists to make the necessary adjustments. Greg argues against this practice and offers alternative solutions for rough plumbing that avoid damaging the structural integrity of the home.
Why Cutting Truss Joists Should Be Avoided
Truss joists are engineered beams that form the ceiling of a floor below and the floor structure of the room above. They are designed to carry a specific amount of weight, and cutting into them can compromise their structural integrity. This can lead to sagging floors, cracking walls, and other problems.
There is “no reason why you need to do something like this and just hack this stuff up and guess at it.” It’s important to remember that safety should be the top priority during any construction or renovation project.
Planning to Avoid Cutting Truss Joists
Communicate with the Plumber Early: Greg recommends that plumbers collaborate with framers before construction begins. This allows the plumber to identify any potential conflicts between the plumbing layout and the truss joists. The plumber can then adjust the plumbing accordingly to avoid cutting into the joists.
Consider Raising the Bathtub: If there is enough clearance, raising the bathtub slightly can be an easy solution. An inch or two of extra space might be enough to ensure that the drainpipes fit without needing to modify the joists.
Rough Plumbing Tips to Avoid Cutting Truss Joists
Shortening the drain pipe might create enough slack to maneuver the fitting into place without needing to notch the joist. This however would create an angled connection instead of a 90-degree angle. The video acknowledges that some plumbers might not approve of this approach, but it offers it as a potential solution.
Using different plumbing fittings available that could help avoid cutting the joists. For instance, a 90-degree elbow fitting might be used to divert the pipe in a different direction.
Additional Considerations
Reinforcing the wall studs with notches might be an option if the wall is not load-bearing and only a small section needs to be moved. However, it emphasizes that this approach should only be considered as a last resort.
The video concludes by reiterating the importance of planning to avoid problems altogether. By planning ahead and communicating with other tradespeople involved in the construction project, plumbers and homeowners can ensure a safe and successful bathtub installation.
