How to Connect a Pool Backwash Hose to Filter

Backwashing your pool is a cost-effective way to maintain excellent water quality. The process ensures that your filter gets rid of debris, bacteria, and algae effectively. However, after continued use, your backwash hose dries out and eventually cracks.

Whether it’s your first-time practicing backwashing, or you need help replacing an existing hose, this article is for you. You’ll find a step-by-step guide on installing a pool backwash hose. Read on to discover how to perform this task for DE and sand filters.

How to Connect a Pool Backwash Hose

Step 1: Determine the Ideal Size

Before installing a backwash hose, identify the correct size. You can find various sizes in stores, but the most common ones are two inches in diameter and 25, 50, or 100 feet in length.

To measure the length you need, lay the hose flat on the ground from the pipe to the drainage. Afterward, give an allowance of one to two feet. Cut your new hose accordingly with a knife.

Step 2: Remove the Existing Hose

If you have an existing hose, loosen the clamp screws with a screwdriver. You don’t have to take off the screws completely to remove the existing hose, but you might need a knife to cut the old one.

Step 3: Clamp the Hose to the Backwash Pipe

Next, stretch one end of the hose and slide it over the pipe. Insert three inches of the hose into it. Remember, this step takes some getting used to.

Afterward, put the existing or new clamp over the hose and tighten it with a screwdriver.

Pro tip: You can cut a small piece of pipe and perform this step on the other side of the hose to prevent it from flipping around when you backwash your pool.
