Build-In Installation
Compare build-in DB1400 and DB1500 where flow restriction and backflow prevention are needed inside the hand shower, overhead shower or pipework.
Separate the Check Function from Flow Restriction
A check valve prevents reverse flow; a restrictor limits forward flow. Required functions, available depth and removal access determine which models to compare.
Start with the Task
Regular service access
Compare T-shaped DT1814 and DT1815 where the combined component needs regular removal for cleaning or replacement.
Combined functions with service access
Compare DB for internal installation and T-shaped DT1814 / DT1815 for regular removal and cleaning.
What to Check Before Choosing
01
Define the functions
Identify whether the position needs a check function only or flow restriction as well.
02
Measure the cavity
Record bore, usable depth, flow direction and sealing position. Compare DB models for internal installation.
03
Check removal space
For regular servicing, check the DT removal direction and access in the complete product.
04
Test the assembly
Use the selected sample to check forward flow, check-valve operation and sealing before confirming the order.
Choose a Model for the Application
DB / DT | Internal Fit and Service Access
DB models suit internal combined restriction and check positions. T-shaped DT1814 / DT1815 suit shower and pipe positions requiring regular removal and servicing.

DB models address internal installation, while DT models provide service access.
Check dimensions, sealing and maintenance access separately from the required water-saving and backflow functions.
Ordering and Customization
Specify Direction, Depth and Access
Provide the cavity drawing, installation position and functions. Add supply pressure and target flow when restriction is needed, and state whether regular removal is required.
Selection Questions
Which models suit build-in installation?
Compare DB1400 and DB1500 by the internal cavity and sealing position. For regular removal and cleaning, review T-shaped DT1814 / DT1815.
Do I need a combined component for a check-only requirement?
Compare DB or DT for combined restriction and check functions in internal or service-access positions.
Which models should I compare for regular cleaning?
Review T-shaped DT1814 / DT1815 and check that the complete assembly provides a removal path.
Share the Waterway Drawing and Required Functions
Mark depth, flow direction and maintenance access. State whether the position needs backflow prevention only or flow restriction as well.
