Description
Watts Dormont WD-35-L Low-Profile Grease Interceptor
35 GPM • 70 lb Grease Capacity • 4" No-Hub ConnectionsKeep fats, oils and grease out of your drain lines without eating up valuable under-sink space. The PDI-certified WD-35-L delivers proven 90 % separation efficiency at a full 35 gallons-per-minute flow rate—all in a slim, 11 ⅞″ low-rough-in profile that fits where standard interceptors can’t.
Why Choose the WD-35-L?
- Low-profile design – only 11 ⅞″ high, ideal for on-floor or recessed installs with limited rough-in depth.
- High holding capacity – traps up to 70 lb of grease before pump-out is required.
- Rugged, epoxy-coated steel body resists acids and corrosion inside & out.
- Skid-proof steel cover with neoprene gasket and hex-head center bolt keeps odors sealed in.
- Removable baffle assembly and deep-seal trap with clean-out for fast, tool-friendly maintenance.
- External cast-iron flow-control fitting included to assure rated GPM and separation efficiency.
- No-hub inlet & outlet standard; threaded connections available at no extra charge—just add “THD” to the part number.
- PDI-G101 & UPC listed for code-compliant installations nationwide.

Ordering Tips
- Choose the interceptor size based on the calculated sink flow rate (see plumbing code or sizing chart).
- Add the optional “THD” suffix for factory-installed 4″ threaded connections at no additional cost.
- Always install the supplied flow-control fitting and vent per local code to maintain PDI performance.
Regular pump-out frequency will vary by menu and volume. Inspect weekly during start-up and establish a cleaning schedule before grease reaches 25 % of total liquid depth.
