Opella Dual-Flush Siphon 220mm is rated 4.5 out of 5 by 343.
Rated 1 out of 5 by from Junk a complete piece of junk. i am a plumber and bought a couple of these for van stock. have used them before with no issues. recently attended a job to replace a siphon and i had issues with BOTH the units i was carrying. the first one refused to flush completely! the second one flushed but didnt stop dribbling water into the bowl. i cant believe the trouble i had and the time wasting... id never use these cheap and nasty units again... Grrrrrrr! id recommend spend a bit extra to avoid the aggravation

Rated 5 out of 5 by from Toilet syphon Toilet stopped flushing over the weekend, so thought the worse and a new toilet was in order, after further investigation it looked like it was the syphon, So decided to give it a whirl to replace myself as a cheaper alternative to buying a new toliet, I found this quite easy to fit as an amateur DIY'er, seems well built and good value for money
