Reich 90° Elbow for 28 mm Waste Water Pipe - Push-Fit Fitting for Grey Water Systems in Motorhomes and Caravans
- Reich 90° elbow for 28 x 1.5 mm waste water pipes. It turns the grey water drain at a right angle and is fitted by pushing, with no glue or screws. For motorhomes and caravans.
The Reich 90° elbow is a fitting for the push-fit 28 x 1.5 mm waste water pipe system. It turns the pipe at a right angle and has sockets on both ends, so you push the pipes straight in. It works well in corners of the interior, where a pipe passes through the floor and wherever the grey water line has to turn within a short distance.

A right-angle turn
- turns the pipe by 90°
- sockets for Reich 28 x 1.5 mm pipe on both ends
- dimensions 61 x 61 mm, socket outer diameter 32 mm
- push-fit assembly, no glue, threads or welding
- works from -40 °C to +80 °C
- black, impact resistant plastic
The elbow is compact, so it fits into tight spots along walls and in cabinet corners.
How the Reich push-fit system works
The Reich waste water system consists of black 28 x 1.5 mm pipes and fittings: couplings, elbows, T-pieces and hose adapters. All parts are joined by simply pushing them together. You need no glue, no threads and no welding tool, and the manufacturer states that the joints are fully tight. This lets you build the grey water installation of a motorhome or caravan with basic tools and later take it apart, extend it or change the route.
Where a 90° elbow is used most
A typical spot is the transition from the vertical section under the trap to the horizontal pipe running to the tank. The 90° elbow also helps in a corner of the interior, when the pipe has to go around a cabinet or a wheel arch. Because the turn is sharp, make sure the pipe after the elbow has enough fall. If you have more space and the drain carries a lot of dirt, consider two 45° elbows for a gentler curve.
Installation step by step
- Plan the route from the sink, washbasin or shower drain to the grey water tank.
- Cut the pipe square to its axis, ideally with a pipe cutter, and remove burrs from the edge.
- Push the pipe all the way into the socket of the fitting.
- Lay the pipes with a steady fall towards the tank so that water drains by gravity and does not stand in the lines.
- Fix the pipes to the wall or floor with clips so that the joints do not move while driving.
- After installation pour water into the drain and check every joint.
Typical uses
- grey water installations in motorhomes, caravans and camper vans
- drains from the sink, washbasin and shower tray to the grey water tank
- repair and rebuild of existing installations with 28 mm pipe
- DIY conversions where quick assembly without glue matters

Two sockets, no extra connectors
Both ends of the elbow have sockets, so you push the pipes straight in without couplings or adapters. After installation flush the system with water and check the joints before you close the interior.

Frequently asked questions
Is this elbow suitable for drinking water?
No. It is a fitting for draining grey water in the Reich 28 mm system and is not part of a drinking water installation.
Do I need a coupling to connect the pipe to the elbow?
No. The elbow has sockets on both ends, so you push the pipes straight in.
Do the joints need glue or sealant?
No. You push the pipe all the way into the socket. The manufacturer states that the joint is fully tight without glue or tape.
Does it fit other 28 mm pipes?
The fitting is designed for Reich 28 x 1.5 mm pipes. With pipes from another brand tightness is not guaranteed, so it is best to use parts from one system.
