Air assist toilet not holding water

[georgew]

My air assist flush toilet is not holding water in the bowl. This just started, I tried to clean the white area on the toilet and tried to wipe the flapper with dawn. Still leaking. Looking for suggestions to repair.

George good to see I'm not the only one that keeps crazy hrs. Get the rebuild kit pull it and rebuild it.

Is it a microphor? see below for parts.

Replacing the rubber on the flapper valve is a good next step.

Thank You WJohnson, yes its a microphor. Ive figured out the timing mechanism for the flap open/close. Right now it draws an extreme amount of water. Ive even throttled it by closing the ball valve 97%
Mine doesnt seem to have any other set screws for adjustment so my gut tells me its all tied together. Ill start with that hex screw and remove the plug....see what comes of it

Patrick, the Microphor toilets are VERY sensitive to both water and air pressure. Make sure you have the correct pressure on both. It is best to order a total rebuild kit from Mullaney, remove the valve and replace every o-ring and part in the kit. Clean the valve thoroughly with alcohol, keeping it VERY clean. If rebuilt properly, they are dependable and functional. I no longer own the bus with the Microphor, but I struggled with it until the pressures were correct. Sorry I don't recall the pressures needed, but I will try to find and post. I would bet the Mullaney folks will know. The business was passed down to a daughter if I remember.
Just checked...water pressure 20-50 psi (35 optimum) , air pressure 60-65psi.

Guys the best place for a Microphor is the bottom of the ocean. In their day it was a good option buy between over priced parts air and water leakage they are finnicky at best. Many many of us got tired of the constant tinkering and the smell. If you need to smell it twice that's your choice. Gravity drop.

The Tecma Silence Plus is a good replacement, slight different foot print but easily managed. Built in macerator and in my 07 was a top 3 upgrade of anything I ever did to that bus.

Being in MT on a holiday weekend and using a 5 gallon bucket convinced me. Also your skill level to change out the air lines and water line in close quarters is about a 7 not many DYI can do it right.

Microphors were a steady product back in the day but better options out there boys.

This is the Tecma Silence plus 2 and a Biobidet2000 that replaced my Microphor air toilet. Was a job but well worth it in the end.

Truxton at this point I agree...but she is so pretty though. looks the part. We all know that the pretty ones get all the chances, all the benefits of the doubt. I have never had anything pretty that wasnt troublesome

Patrick, don't give up, if you don't want to change....your toilet CAN be fixed. Take your time, make sure your pressures (water & air) are correct, rebuild your valve.
Think about it...What has changed on your toilet causing it to stop working properly?
