Vent pipe on Saniflow Sanibest pro macerator

[woodman-46]

Hello,
We have a Turboflush macerator at the moment that is constantly getting blocked and not emptying the chamber. I want to replace it with a Saniflow Sanibest one that is more powerful and efficient. On the the Turboflush one there is no vent pipe fitted but according to articles the Saniflow one needs a vent pipe. Unfortunately there is no way of getting a vent pipe anywhere to the outside
Is it absolutely necessary to have a vent pipe on the new Saniflow or can this be left off. The machine is only used for the toilet and nothing else.
Thanks in advance for any advice
James
Ps the Saniflow Sanibest is pictured here.

I think that you are misunderstanding the written words re venting. If the Turboflush is often getting blocked then look at the installation rather than blame the muncher and the Sanibest is a very, very noisy machine named by someone with a sense of humour.

I'm only guessing but I would think that the reason for having it vented would be to stop it syphoning. When we had that problem one of these https://www.google.com/search?q=air...hiABBjHARivAZgDAJIHAjEwoAeMUg&sclient=gws-wiz fitted inside next to the macerator cured the problem and I would think would be the same as having it vented. Perrhaps just pumps could confirm that.

I never guess, I ask questions instead. I can think of a case where the AAV in your link might be used if the installation was not as intended.

I'm not "blaming" anything. We've had the machine for about 10 years. Used to work perfectly with exactly the same plumbing setup but over the last month's is not emptying itself/ mulching properly. Have taken apart and see no blockages or damage. Perhaps mulcher has reached end of its life?
Simply asking whether an air vent is necessary on Saniflow mentioned to make it work properly. Does not having a vent reduce the performance of the actual machine and the way it works? It will only be used for toilet.
Thanks for advise on that part so far

Ours was installed as per the instructions but syphoned the water from the bowl. The Saniflo engineer could not stop it happening with the model we had and Saniflo supplied a different model at no cost. This had the same symptom until the valve was installed so I wondered if venting would be an alternative that was preferred these days ( we have had ours over 20 years ).

At ten years I would say it`s time for a new one rather than repair however I would replace with another Turbo rather than the more expensive and much noiser Best. Both models have the required venting built in but the Best needs no addditional vent pipe as you stated it the opening post.

Two models of pump showing the same problem with water level in the pan really points towards a bad installation. What you did was cure a problem created by another problem as all models have a built in vent.
