Dry Hydrant - Clamp

Product overview The Dry Hydrant Support Clamp is a heavy-duty mounting clamp used to secure and stabilize the suction piping in a dry hydrant installation. By anchoring the 6-inch or 8-inch pipe to a fixed structure, the clamp maintains alignment, prevents sagging and joint stress, and helps the system withstand ice, current, debris, and pump suction loads. The result is a more reliable, longer-lasting dry hydrant that drafts efficiently when needed.

How it’s used with our dry hydrant products

• Suction line support: Holds the horizontal suction run from the shoreline to the strainer so it stays on grade and drains back to the source after use.
• Strainer end stabilization: Supports the pipe at or near the strainer to resist movement from flow, ice, and debris.
• Riser/headwall anchoring: Secures the riser near the pumper connection or to a headwall, bulkhead, pier, or post to keep the inlet aligned and accessible.
• Intermediate bracing: Adds support along longer runs to reduce bending loads on couplings, elbows, and glued or gasketed joints.

Typical mounting locations

• Concrete headwalls, culverts, or abutments (with appropriate anchors)
• Piers, docks, pilings, or timber posts (with lag bolts or through-bolts)
• Steel or aluminum brackets/backer plates (using site-appropriate hardware)

Compatibility

• Designed for use with our 6" and 8" dry hydrant assemblies, including suction pipe, elbows, risers, and strainer components.
• Works with common dry hydrant pipe materials (e.g., PVC or HDPE). Verify pipe outside diameter and any insulation/coating thickness to ensure proper clamp fit.

Key benefits

• Maintains pipe alignment and grade for faster, dependable drafting
• Reduces stress on joints and fittings, extending system life
• Helps resist loads from ice, flow, and accidental impact at the shoreline
• Improves overall reliability and lowers maintenance needs

Selection guidance

• Choose the clamp that matches your dry hydrant’s nominal pipe size (6" or 8").
• For insulated or coated pipe, ensure the clamp accommodates the increased outside diameter or use a protective liner.
• Use corrosion-resistant mounting hardware suitable for the structure and environment.

Installation basics

• Plan support points at the strainer end, near the riser, and at intervals along the run as site conditions require.
• Position the pipe with a slight slope back toward the water to allow drainage after drafting.
• Wrap the clamp around the pipe and attach it to the structure using appropriate anchors/bolts.
• Tighten evenly until secure without deforming the pipe; avoid over-tightening, especially with PVC.
• Where thermal movement is a concern, make one support the “fixed” point and allow guided movement at others.
• After installation, perform a draft test and recheck all fasteners.

Maintenance

• Inspect at least annually and after freeze-up, high-water, or storm events.
• Check for loosening, corrosion, abrasion, or misalignment; retighten or replace hardware as needed.
• Keep the strainer area and supports clear of debris and ice.
