AKW Silentflow+ PGTF 22mm Pumped Waste

Product Overview

The SilentFlow+ is a low-profile pumped shower waste designed to address the noise problem that affects most pump and waste combinations. Its internal geometry — flow guides, a balanced chamber design, and optimised outlet path — reduces the gulping and turbulence that cause conventional pumped wastes to be audible during and after a shower cycle.

Noise level testing shows the SilentFlow+ performs comparably to the nearest competitor's quiet-rated waste at 11 L/min and outperforms it at higher flow rates, making it a better match for the AKW DigiPump range which can deliver up to 20 L/min.

The waste connects directly to the DigiPump M11, M17, and M20 via an integrated 22mm John Guest push-fit fitting. Connection to 15mm pipework is via a John Guest adaptor, supplied. It is designed for installation in Tuff Form wet area formers with vinyl floor covering, and the bayonet cover is a direct replacement fit for existing TF75 installations.

The cover is removable for cleaning without tools — rotate anti-clockwise to remove — and can also be screwed down with two M4 screws for added security.

Made from white ABS plastic for internal building use. Patented design GB 2373515. Lifetime guarantee against manufacturing and material defects.

Key Features

Quiet operation at all flow rates — internal flow guides and optimised chamber geometry reduce gulping and turbulence noise throughout the pump cycle, not just at low flow.

Compatible with all three DigiPump models (M11, M17, M20). Integrated 22mm John Guest push-fit outlet; 15mm JG adaptor included. Bayonet cover removable without tools for routine cleaning; optional screw-down fixing for security. Direct bayonet replacement for existing TF75 installations. Suitable for Tuff Form formers with vinyl floor covering. 

Low maintenance design — the waste body can be rodded to clear blockages without disassembly.
