As per the title really.. After a slight misshap with a gallon or two of water syphoned onto the floor, i bought a non-return valve for the nutafin kit. As it works using pressure to force the CO2 through the valve, does everyone who also uses this valve find that the CO2 bubbles come in bursts every few seconds, with a number of bubbles at a time.?

ye...mine does that! hate it! i think there are glass non return valves which are suppose to work a bit better...but mine is a nightmare with trying to count bubbles through the bubble counter...it doesn't effect the diffuser though
 
So using a non return valve(to stop yeast getting into the tank) is still affective? Does it actually stop the mixture getting in and do the plants still grow?
 
Not sure about the non-return valve, but I recently discovered that if you play with the amount of the ingredients in your mixture, you can reduce the stuff going into the tank. I was getting so much crud building up on my ladder that I was taking it out and cleaning it 2-3 times a week. I put in a little less sugar and lowed the water level in the bottle by about half an inch and the problem virtually disappeared.
 
So where in the system did you put the check valve? It should be as close to entering the tank or a diffuser as possible. The plastic check valves are also somewhat questionable. CO2 corrodes plastic!

The NRV will never stop the yeast getting into the tank.

The idea is that it is a non RETURN valve, meaning that water will not siphon back into the source of the CO2 especially important if you are using pressurised.

If it were to stop the yeast getting in the tank it would also stop the CO2 getting in the tank.

I would just use a little less yeast or have the water level in your CO2 cannister.
