Compression fittings involve inserting the pipe into a fitting and then tightening a nut around it, creating a secure seal. This method is straightforward and effective for smaller pipes, but it may not be as strong for larger diameters.

For larger PVC pipes, you might consider using elbow fittings, tee fittings, or couplings. Elbow fittings are used to change the direction of the pipe, providing a 90-degree turn. Tee fittings, as the name suggests, have a T-shaped design and are useful for branching off pipes. Couplings, also known as union fittings, allow for the connection of two pipes without the need for a 90-degree bend. When selecting fittings, it's essential to match the pipe size to the fitting's specifications to ensure a proper fit.

The design of your boat also plays a significant role in fitting selection. If your boat has a specific layout or requires certain angles for the pipes, you might need to opt for fittings that accommodate these requirements. For example, if the pipes need to run along the deck or inside the hull, you might choose fittings that allow for a smooth curve or a specific orientation. Consider the accessibility and maintenance of the pipes as well. Fittings that allow for easy disassembly and reassembly can be beneficial if you need to access the pipes for repairs or maintenance in the future.

Additionally, the material of the fittings should complement the PVC pipe. Most PVC fittings are made of PVC or a compatible material to ensure compatibility and prevent damage to the pipe. It's crucial to avoid using metal fittings, as they can corrode and potentially damage the PVC over time. Always check the manufacturer's guidelines and recommendations for the specific fittings you plan to use.

In summary, when fitting PVC pipes to a fiberglass boat, the key is to match the pipe size and boat design requirements. Choose fittings that provide a secure connection, accommodate the desired pipe orientation, and are compatible with the PVC material. By carefully selecting the right fittings, you can ensure a professional and long-lasting installation for your boat's plumbing system.
