Our 110mm Low Back P-Trap is an essential heavy-duty fitting for soil and underground drainage systems. Specifically designed with a “low back” profile, it allows for high-capacity waste discharge in installations where vertical depth is restricted, such as ground-floor wet rooms or shallow drainage trenches.
High-Capacity 110mm Bore: The industry standard for main soil pipes and underground drainage (4-inch).
Low-Back Design: Minimizes the height required for installation, making it ideal for tight floor voids.
Durable uPVC Construction: Manufactured to withstand ground pressure, thermal expansion, and domestic chemicals.

A 110mm low back P-trap is a specialized drainage fitting used to provide a water seal in high-volume waste systems. While smaller traps are used for sinks, the 110mm (4-inch) version is required for connecting floor-level waste outlets—such as commercial showers or large floor gullies—directly into the main soil run. The “low back” refers to the reduced height of the inlet side, which is a lifesaver for installers working with limited depth under a concrete slab or between floor joists.
In any drainage system, preventing sewer gases from entering the building is the number one priority. This 110mm P-trap maintains a robust water seal that acts as a permanent barrier. Because it is designed for 110mm pipework, it ensures that even high-flow appliances can discharge water rapidly without the risk of backing up. The smooth internal bore is engineered to prevent the accumulation of debris, reducing the likelihood of blockages in hard-to-reach underground locations.
At ECO HEAT SHOP, we supply drainage components that meet strict UK building standards. This 110mm low back P-trap is manufactured from high-grade, impact-resistant uPVC. It features captive ring-seal joints (push-fit), which allow for a fast, watertight installation that can accommodate minor ground movement without leaking. The terracotta/grey finish is compatible with standard UK underground and soil pipe systems, ensuring a seamless fit every time.

Installation Advice: When installing a 110mm low back P-trap, always use a silicone-based pipe lubricant on the rubber seals to ensure a smooth connection. Ensure the trap is sat on a level, compacted bed of pea shingle or sand to prevent sagging once the trench is backfilled, which could break the water seal
