Drainage Saddles

Drainage saddles provide a fast, reliable and cost-effective way to create lateral connections into existing drainage pipelines. Whether upgrading a sewer network, adding new property connections, or installing surface water drainage, these fittings eliminate the need for factory-made junctions or large excavation works. They offer strong sealing performance, straightforward installation, and compatibility with a wide range of host pipe materials and diameters.

What Are Drainage Saddles Used For?

Drainage saddles are designed to connect a branch (lateral) pipe into a main pipeline by cutting a precise hole in the host pipe and securing the saddle over it. This creates a watertight connection suitable for foul water, surface water and stormwater drainage systems. They are ideal for:

  • New sewer or surface-water connections
  • Road gully and building drainage links
  • Retrofitting into existing networks without full pipe replacement
  • Minimising excavation, disruption and installation time

Fernco Unisaddle (DN450+)

A heavy-duty saddle designed for connecting lateral pipes into large-diameter concrete pipelines (DN450+). It delivers extremely strong sealing performance, WRc-approved reliability and long-term durability.

Key Advantages:

  • Creates new junctions in existing sewer or surface water mains without major excavations
  • Universal sealing system accommodates a wide variety of host pipe brands and tolerances
  • Withstands up to 20 kN vertical load for high-demand infrastructure environments
  • Rated for 1 bar pressure and vacuum conditions
  • Allows up to 15° lateral deflection, offering useful installation flexibility
  • Compatible with DN450 - DN1500 laterals

Ideal Applications:

  • Major sewer upgrades
  • Infrastructure and utilities projects
  • Deep or high-load drainage pipelines
  • Retrofitting new property drainage into existing mains

Fernco TA Saddle

A flexible, quick-fit saddle designed for smooth PVC sewer and surface water pipes. It eliminates the need for pre-fabricated junctions and enables rapid on-site lateral connections in 45° or 90° options.

Key Advantages:

  • Suitable for main pipe diameters 160–600 mm (depending on model)
  • Choice of 45° or 90° connection angles
  • Installs quickly with no specialist equipment
  • Withstands up to 0.5 bar internal pressure
  • Reduces project costs by avoiding manufacturer-made junction pieces
  • Durable PVC and stainless steel construction withstands typical site conditions

Ideal Applications:

  • New build housing developments
  • Road gullies and surface water links
  • PVC stormwater and sewer networks
  • Sites requiring fast, economical installation

Fernco Storm-T Saddle

A specialised saddle for stormwater and rainwater systems, connecting DN150 lateral pipes into DN300–600 host pipes. It features a fully tool-free installation once the cored hole is prepared, and requires no adhesives or concrete.

Key Advantages:

  • Universal fit for a wide range of plastic stormwater pipes
  • Tool-free assembly with simple push-fit operation
  • No adhesives or curing time required
  • Multi-zone internal rubber seals ensure watertight performance
  • Tapered internal edges promote smooth flow and reduce blockage risk
  • Designed with a depth-setting system to accommodate different wall thicknesses
  • Rated to 0.5 bar pressure

Ideal Applications:

  • Surface water and rainwater diversion systems
  • Attenuation tanks and soakaway systems
  • Retrofitting laterals into existing stormwater pipes
  • Fast installation in all weather conditions

Fernco Unisaddle (DN300–450)

A robust saddle for connecting lateral pipes into DN300–450 concrete or clay pipelines. It requires minimal excavation, provides excellent sealing performance and is WRc-approved for UK water authority acceptance.

Key Advantages:

  • Suitable for concrete and clay host pipes DN300–450
  • Rated to 1 bar pressure and vacuum conditions
  • Withstands 20 kN vertical load and up to 5% pipe deformation
  • Accepts 7° lateral deflection, aiding alignment on complex sites
  • Jetting-resistant up to 180 bar, ensuring long-term reliability
  • Constructed from EPDM, ABS and stainless steel for durability

Ideal Applications:

  • Surface water and sewer system upgrades
  • Connecting new property drainage to mid-sized mains
  • Clay drainage refurbishment projects
  • Situations where excavation access is limited
