To replace a 90-degree PVC elbow, start by turning off the water supply to prevent leaks. Next, cut the PVC pipes connected to either side of the elbow, ensuring the cuts are straight and clean using a PVC cutter or a handsaw. Leave enough pipe on each side to attach a new elbow. After cutting, remove the old elbow. If it's glued, you might need to cut it out entirely. Clean the edges of the pipes with sandpaper to remove any burrs or old glue. Apply PVC primer to the outside of the pipes and the inside of the new elbow. Then, apply PVC cement over the primed areas, and quickly insert the pipes into the new elbow, making sure they're fully seated. Hold the assembly in place for a few seconds to ensure a strong bond. Finally, allow the cement to cure according to the manufacturer's recommendations before turning the water back on.

Fiber plays a vital role in maintaining a healthy diet, with benefits including digestive health, weight management, and reducing the risk of chronic diseases such as heart disease, diabetes, and certain cancers. Found in fruits, vegetables, whole grains, and legumes, dietary fiber comes in two forms: soluble and insoluble. Soluble fiber dissolves in water to form a gel-like substance, helping control blood sugar and reduce cholesterol. Insoluble fiber does not dissolve, aiding in digestion and preventing constipation by adding bulk to the diet. Integrating a mix of these fibers helps promote a healthy gut, balance blood sugar levels, and support overall well-being. Adults are recommended to consume 25-30 grams of fiber daily, yet many fail to meet this target. To increase fiber intake, incorporating a variety of fiber-rich foods across meals is advised, alongside a gradual increase in intake to allow the digestive system to adjust.
