Thank you so much.. I haf been having. Problems for days trying to install this fluid master kit. I realized I never adjusted it for to fill water at a certain level. I was too scared to flush because water would go into my other bathroom from the toiler being to full of water. I folkowed step bt step and now the water cuts off at proper level and no more water leakage in the other bathroom. Thank you so much..

Removal of the plastic nut connecting this unit's water supply to the toilet has been an absolute nightmare for adding a bidet

This is EXTREMELY different than the printed instructions that come with the kit. I was not planning on taking the tank off the toilet bowl!!!!

If really lucky and a 400a valve stops filling . The top half can be removed where you adjust the height of the big tube. Spiral. With locking collar.. just pull the old one off and put a new one in.. replace the little rubber hose and set the full height....

I replaced my entire unit and the constant running stopped but every 30 seconds or so it makes a sound like it is releasing air (I see bubbles). I'm glad I don't have the constant running but wonder why I releases air every 30 seconds or so? Does it need to be adjusted? Thank you.

Is the fill tube really supposed to go down the overflow drain? Seems like a waste of water.

There is zero mention of what you do with the shank washer. It’s not clear on the box and it’s not clear in this video.

I did not need any music. I was hoping a licensed plumber would talk slow on HOW TO

I replaced it but every 5 mins I hear my toilet running. How can I stop that or what so I need to adjust?
