Swimline in-line Chlorine Feeder 8750 — 9 lb Automatic Adjustable Output, UV‑Resistant

The HYDROTOOLS by Swimline 8750 is a heavy-duty in-line automatic chlorine feeder that holds up to 9.0 lbs of tablets and delivers adjustable, continuous chlorination for both above-ground and inground pools.

Designed as a direct, tool-free replacement for many major-brand chlorinators, the Hydrotools 8750 simplifies pool chemical management by dosing chlorine automatically through your existing pump and filter plumbing. Built from double-reinforced thermoplastic with UV and corrosion resistance, this feeder is intended to withstand outdoor conditions and provide long-lasting service while reducing manual handling and frequent refills.

How does the 8750 install into my current pool plumbing?

Installation is straightforward: the unit connects inline with your pool’s return line using standard plumbing adapters, so heavy modifications or specialty tools are typically unnecessary. It functions while your pump runs and integrates with most common filtration systems.

• Mounts inline between pump and return with common adapters
• No specialized tools required for most setups
• Compatible with both above-ground and inground pool plumbing
• Works automatically while the circulation system is on

What customization or control does it provide for chlorine output?

The feeder includes an adjustable control mechanism so you can fine-tune the rate of tablet dissolution to match pool size, bather load, and local conditions. This lets you avoid overfeeding chemicals while maintaining effective sanitization when the pump runs.

• Turn the control to increase or decrease feed rate
• Settings let you adapt to seasonal or usage changes
• Helps reduce chlorine waste by targeting output to need
• Simple manual adjustment—no electronics to program

What materials and durability features protect it outdoors?

Hydrotools engineered the 8750 from commercial-grade, double-reinforced thermoplastic to resist UV degradation and chemical corrosion, extending operational lifetime. The reinforced molding and assembly improve structural integrity under normal pool system pressures and weather exposure.

• Double-reinforced thermoplastic housing for strength
• UV-stable construction to resist sun damage
• Corrosion-resistant materials for long-term use
• Designed for continuous service with standard pool pumps

Can I use different sanitizers or tablet sizes in the feeder?

The 8750 is sized for standard pool tablets and accepts common tablet-type sanitizers; always follow chemical manufacturer guidance and local regulations. While bromine and similar tablets may be compatible, verify compatibility with components and avoid mixing chemicals directly in the feeder.

• Holds standard pool sanitizer tablets (check sizes before filling)
• Accepts many tablet-based chlorine or bromine products when used properly
• Do not combine different chemicals inside the feeder
• Follow label directions for sanitizer use and safety

Who is this for: The HYDROTOOLS 8750 is suited for pool owners and maintenance professionals who want reliable, low-effort sanitization for above-ground or inground pools. It appeals to anyone replacing an aging in-line feeder, upgrading to a more durable housing, or seeking a pump-driven, adjustable chlorination solution that integrates with existing plumbing and reduces manual dosing frequency.
