Deargooday 2" Inline Zinc Anode 104-D for 2" Pool Plumbing — Transparent Housing, Copper Bonding Wire

The Deargooday 2" Inline Zinc Anode 104-D is a sacrificial corrosion protector that installs inline on 2" pool plumbing to reduce galvanic corrosion in saltwater systems.

If your pool system uses a salt chlorinator or has exposed metal fittings, the Deargooday 104-D zinc anode provides a simple, replaceable way to slow electrochemical wear on pumps, heaters, rails and light housings. Housed in a transparent inline body with a pre-attached copper bonding wire, this anode is sized for standard 2" pipes and designed for straightforward plumbing integration without cutting or reconfiguring major equipment.

How does this zinc anode protect pool equipment?

The Deargooday zinc anode acts as a sacrificial metal—meaning it corrodes in place of other metal parts in the pool plumbing and equipment. By creating a preferential corrosion site, it diverts galvanic current away from more valuable metals, helping preserve pumps, heaters, and fittings.

• Provides a lower-potential metal surface that corrodes first, reducing damage to connected metal parts.
• Connects to the pool bonding system via the supplied copper wire and bronze split bolt for effective protection.
• Transparent housing allows quick visual checks of anode consumption.

Where and how should I install the inline anode?

Install the 104-D inline anode on 2" pipe runs where current or salt exposure is highest—commonly between the pump and filter or between the filter and heater. The unit is designed to fit standard 2" plumbing; orient it downward or horizontally for best performance.

• No major plumbing changes needed; place inline and secure with existing fittings.
• Attach the supplied copper wire to the pool equipment bonding wire using the included bronze split bolt.
• Prime the pump and use the vent/bleeder to remove trapped air after installation.

What maintenance does the 104-D require and how long will it last?

Routine maintenance is minimal: inspect the transparent housing periodically and lightly sand the zinc rod to remove surface oxidation every six months. Replace the anode when it has worn down to about half its original diameter—typical service life is roughly three years, depending on water chemistry and use.

• Visual checks through the clear housing let you monitor anode wear quickly.
• Surface cleaning with fine sandpaper prevents insulating oxidation layers from reducing effectiveness.
• Exchange the anode at ~50% consumption to maintain protection levels.

Will this work with my saltwater pool system?

Yes—this model is specifically intended for saltwater systems and other pools with higher corrosion risk. It pairs well with metal heat exchangers, salt chlorinators, ladders, and light housings to reduce galvanic deterioration when properly bonded into the system.

• Built for 2" plumbing commonly used on residential pool equipment lines.
• Designed to complement existing bonding and grounding arrangements in pools.
• Helps limit plaster staining and metal erosion typically accelerated by salt systems.

Who is this for: Pool owners and professional service technicians who need a low-effort, visible sacrificial anode to protect metal pool components—especially in saltwater or high-corrosion environments. If you want a maintenance-friendly inline protector for 2" lines with a clear housing, pre-attached copper bonding wire, and straightforward installation, the Deargooday 104-D is built for that need.
