Slotted vs Unslotted. Which should you buy?
The main difference between a slotted and an unslotted siphon is, a slotted siphon is designed for sinks with overflow. So if you are buying a sink with an overflow included, our recommendation would be to buy the slotted option, and vice-versa, if your sink doesn't include an overflow, buy the unslotted option.
