U.S. Pool Supply Pool Backwash Hose - weather, chemical and burst proof

If you own an above ground pool, a good backwash hose is one of those inexpensive upgrades that pays off every time you clean your filter or drain a little water. The U.S. Pool Supply Pool Backwash Hose (available in 1.5" and 2" diameters and lengths 25 ft, 50 ft, and 100 ft) is built for reliable, low-fuss pump discharge, sand filter backwash, and even temporary sump pump discharge jobs. This post walks you through how to pick the right diameter and length, how to install it and tips to keep it working season after season — all in plain language for above ground pool owners.


Why an upgraded pool backwash hose matters!

A purpose-made pool backwash hose / discharge hose gives you:


  • Faster, cleaner backwashes from your sand filter and pump.

  • The ability to send dirty water far from the pool, foundation, and landscaping.

  • A durable, kink-resistant option that stores neatly between uses.


Using the right diameter and length matters — so let’s break down the options.


1.5" vs 2" backwash hose: which should you pick?


  • 1.5-inch backwash hose — Best for smaller above ground pool pumps and lightweight discharge use. If your pump outlet or backwash port is 1.5" (common on many smaller systems), this size fits without restriction and is lighter to handle.


  • 2-inch backwash hose — Best for higher flow from larger pumps and sand filters. A 2" diameter moves more water with less restriction, so backwash cycles finish faster and put less stress on the hose. Use 2" if your filter/pump supports it or if you want maximum flow for quick backwashes.


Tip: If your pump has a different sized outlet, use a reducer/adapter so the hose fits securely.



Choosing the right length: 25 ft, 50 ft, or 100 ft:


  • 25 ft — Great for directing discharge to a nearby yard or driveway drain. Compact and easy to store; perfect when you don’t need much reach.


  • 50 ft — The most versatile choice for above ground pools. Gives you enough reach to route water away from foundations and landscaping without joining hoses.


  • 100 ft — Ideal when you must send water far away (street drains, distant dry spots) or when local discharge rules require moving water well beyond your property. You can also join two hoses for extra length, but a single 100 ft hose reduces coupler leaks and flow restriction.


How to install your U.S. Pool Supply backwash hose

  1. Match diameter to outlet. Make sure you choose 1.5" or 2" to match your pump/backwash port or use the proper adapter.

  2. Secure with clamps. Use the included stainless steel worm-drive clamps for a leak-free connection.

  3. Lay the hose downhill if possible. Gravity helps the flow and prevents pooled water in the hose.

  4. Aim the end at a safe drain. Avoid discharging chlorinated water into flowerbeds, storm drains, or neighbors’ yards — dechlorinate or direct to approved areas.

  5. Anchor the end. Put a rock or stake to keep the hose from moving during strong discharge.


Best practices & maintenance

  • Rinse after heavy chemical use. Run fresh water through the hose after backwashing to remove chemical residue.

  • Dry & store out of sun. Coil dry and store in shade to prevent UV degradation.

  • Inspect clamps & fittings. Replace rusty clamps to avoid leaks.

  • Winterize in freezing climates. Drain the hose completely and store indoors to prevent cracking.


Environmental & local rules (don’t get fined!)

Many municipalities restrict discharging chlorinated pool water into storm drains. Common best practices:

  • Dechlorinate with a neutralizer (sodium thiosulfate) or wait until free chlorine reads zero before discharge.

  • Direct water to grassy areas where chlorine will dissipate and not harm plants.

  • Check local codes — some cities require permission or specify acceptable disposal methods.


Quick FAQ:

Q: Can I use this hose for a sump pump?

A: Yes — the hose doubles as a sump pump discharge hose for short-term draining and emergency use.


Q: Will chlorine damage the hose?

A: Normal backwashing exposure is expected; rinse and dry the hose after heavy chemical use to extend life.


Q: Can I join two hoses for extra length?

A: Yes — use a coupler, but keep in mind each coupling can slightly reduce flow. A single longer hose (100 ft) is usually better for maximum flow.



Who should buy which model?


  • Small pools and light duty — 1.5" × 25 ft. Lighter and easy to store.

  • Most above ground pool owners — 1.5" or 2" × 50 ft. Best balance of reach and flow.

  • Large yards / long runs — 2" × 100 ft. Maximum reach and fastest backwash cycles.


Final thoughts

A quality U.S. Pool Supply backwash hose is a simple, affordable upgrade that makes pool maintenance faster, cleaner, and less stressful. Choose 1.5" or 2" based on your pump/filter, and pick 25 ft, 50 ft, or 100 ft depending on how far you need to send discharge water.


Ready to simplify your next filter backwash or pump discharge? Pick the size you need — 1.5" or 2" (25 ft, 50 ft, or 100 ft) — and upgrade your above ground pool toolkit today!
