Pool Tool PT104D 2″ Inline Zinc Anode (Slip x Slip)

The Pool Tool PT104D inline zinc anode is a sacrificial anti-electrolysis device designed to protect metal pool and spa equipment — such as heaters, lights, rails, and other submerged metal components — from galvanic corrosion. When connected to your pool bonding system and installed in the 2″ PVC return or circulation plumbing, the zinc anode corrodes first, preserving more costly metals in the plumbing, heater, and fixtures.

Key Features

• 2″ slip-by-slip in-line design — easy to integrate into standard 2″ PVC pool plumbing.
• See-through housing allows visual inspection of the zinc rod to know when it’s time for replacement.
• Includes bonding wire for connection to the pool’s electrical bonding system — ensures proper sacrificial protection.
• No re-plumbing required — installs directly into existing return or circulation line.
• Essential for saltwater pools or any pool with metal heaters, lights, or accessories — helps prevent rust, pitting, and premature metal failure.

Specifications

• Brand: Pool Tool
• Model / Part Number: PT104D
• Connection Type: 2″ Slip x Slip PVC inline fitting
• Installation Type: Inline, placed in return or circulation line
• Included: Inline zinc anode housing, sacrificial zinc rod, bonding wire (standard #8 copper) for proper electrical bonding.
• Application: Pools and spas — recommended for saltwater or chemical environments with metal heaters, lights, rails, or plumbing.

Installation & Use Guidelines

Choose a location in your circulation loop — typically between the filtration system and heater or other metal equipment — and cut the 2″ PVC pipe. Glue the PT104D inline zinc anode in place, following manufacturer’s PVC cement instructions. Connect the provided bonding wire from the anode’s bonding terminal to your pool’s main bonding system (bonding grid or bonding lug) to ensure the anode can properly divert galvanic currents. Check the anode periodically — replace when the zinc rod is consumed to roughly half its original diameter (typically every 2–4 years, depending on pool water chemistry and use).

Why It Matters

Without a sacrificial anode like the PT104D, metal components in a pool — especially heaters, lights, handrails, and stainless fittings — are vulnerable to galvanic corrosion, especially in saltwater systems or pools with high mineral content. Installing the PT104D helps extend the lifespan of metal parts, reduce corrosion-related leaks or damage, and save you money on costly replacements or repairs.
