The difference between a bathroom sink siphon and a kitchen sink siphon
Not all siphons are created equal — and there’s an important difference in size:
Bathroom sink – works with a 1¼" (32 mm) pipe. Examples: GTR40063U (siphon + drain valve and flexible hose), GTR40073MU (+ air conditioner inlet).
Kitchen sink – works with a 2" (50 mm) pipe. Usually includes a dishwasher inlet, drain valve, and flexible hose. Examples: GTA40032U (American), GTE40054U (universal), GTD40052U (double).
Be sure to check your drain size before buying.

📋How to replace a sink siphon — step by step
Turn off the water supply
Before doing anything, turn off the water valve under the sink or at the distribution panel.
Place a bucket underneath
Place a bucket or towel under the pipes — some water will spill when you open them.
Open the old siphon
Unscrew the tightening nut by hand (usually no tools are needed). Remove the old siphon.
Install the new siphon
Connect the new Golan siphon to the drain — make sure the seal is in place. Tighten by hand first, then with a wrench.
Check for leaks
Turn on the water and check that there is no dripping at any connection. Tighten if needed.
How do you know your siphon is failing?
Bad smells from the sink, slow drainage, or water that remains in the sink — these are signs that it’s time to replace the siphon.

Frequently asked questions about Golan siphons
What’s the difference between a regular siphon and a siphon with an inlet?
An inlet (additional entry) lets you connect the hose from the dishwasher, air conditioner, or shower to the same siphon — saving connections and space.
Can I install the siphon myself?
Yes! Golan siphons are designed for self-installation — in most cases, they can be replaced without a plumber.
What should I do if there’s a bad smell from the sink?
A bad smell usually means the water seal in the siphon (waterlock) has dried out. Pour in some water and check it — if the smell continues, replace the siphon.
How long does a siphon last?
With proper use and basic maintenance, a Golan siphon can last for many years.
