Flow Control Elbow Assembly

The Acorn 2570-045-001 is a flow control elbow assembly designed for plumbing drainage systems. It regulates water flow at a rate of 0.5 GPM for use with lavatories, showers, and combination lavatory and toilet valves. The assembly includes a 90 degree plastic elbow, flow control, retainer nut, nylon compression nut, and O-rings for installation.

Replaces worn trap components

This assembly replaces damaged or inefficient drain trap parts to restore proper flow regulation in commercial or residential fixtures. The upgrade is worth it when existing components fail to maintain the required 0.5 GPM rate or show signs of leakage at connection points. It provides a complete kit for standard lavatory and shower valve configurations.

Limited to 0.5 GPM applications

The practical limit of this assembly is its fixed flow rate of 0.5 GPM, which suits standard lavatory and shower installations but not high-demand fixtures. The plastic elbow and nylon compression nut are designed for typical drainage temperatures and pressures only. Installers must verify compatibility with specific valve models before use.

Questions about this item

What size compression nut and O-rings does the 2570-045-001 elbow assembly include for the supply connection?

The assembly includes a nylon compression nut and O-rings sized for the standard lavatory or shower valve inlet, allowing a direct compression joint without separate fittings.

How do you install the 90-degree plastic elbow and flow control without cross-threading the retainer nut?

Hand-tighten the flow control into the valve body, seat the O-ring, then thread the retainer nut by hand until snug before a final quarter-turn with a wrench; over-tightening strips the plastic threads.

When should the internal flow control be replaced to maintain the .5 GPM rate on the 2570-045-001 assembly?

Replace the flow control cartridge if the flow rate drifts above .5 GPM or if mineral build-up cannot be cleared by soaking the plastic elbow in vinegar.
