Double Bowl Sink Strainer And Siphon Kit With Flexible Pipes
Both bowls, one outlet, no rigid pipe to cut on site

What This Product Is And Who It Is For
A complete waste kit for a double bowl sink: two stainless steel strainer bodies, an overflow take-off and flexible siphon pipework joining into one outlet.
It is bought by sink brands and distributors who want the sink and its waste to arrive as one saleable package.
Flexible pipe means the installer does not have to cut and glue rigid waste on site.
Why Buyers Specify It
Fits the cabinet as found
Flexible pipe absorbs the difference between where the sink drains and where the wall outlet actually is.
One outlet from two bowls
Both strainers join before the trap, so only one connection goes to the stack.
Sold with the sink
A matched waste kit removes the most common reason a sink goes back to the counter.
304 strainer bodies
The part that sits in standing water is the part that has to be 304.
What It Fixes In A Buying Programme
Rigid waste has to be cut on site
Flexible pipe removes the cutting and the guesswork.
Mismatched wastes leak at the bowl seat
A kit matched to the sink seats correctly first time.
Two bowls, two outlets, no room
Both bowls join before the trap.

Materials
Strainer bodies and baskets in 304 stainless steel — the part permanently in standing water.
Pipework is flexible plastic with rubber seals. Exact material grades are stated per order.
Customisation Options
- Strainer and outlet diameter to your market's standard
- Pipe length and number of bends
- With or without an overflow take-off
- Packed loose, or boxed with a matching sink
How It Is Made
Form the strainer body
The strainer is formed and the thread is cut for the backnut.
Punch the basket
Basket perforation is punched and deburred so it does not catch.
Assemble the kit
Strainers, seals, backnuts, overflow take-off and flexible pipe are packed as one set.
Check the set
Kits are checked against a parts list before the carton is closed.
Quality Control
- Every kit is checked against the parts list — a missing seal is a returned sink.
- Thread fit between strainer and backnut is tested on a sample from each batch.
- Basket perforation is checked for burrs.

Use Guide
Step 1
Seat the strainer on fresh sealant or the supplied gasket, not on the old one.
Step 2
Hand-tighten the backnut and then check it after the first fill.
Step 3
Keep the flexible pipe falling towards the outlet — do not let it sag into a trap of its own.
Step 4
Clear the baskets rather than pushing waste through.
