I just bought my first house and ran into a problem with both of the toilets. During the inspection toilet #1 functioned normally. The toilet #2 could not be tested because the valve to it was tuned off.

The previous owners had the water service turned off just prior to my buying it. I had the water turned back on today and I bled all the air out of the lines to the faucets and to the bath tub in bathroom #1. When I turned on the valve to either of the toilets and flush it I get a very loud vibration when the tank fills, and the toilet fills very slowly. I presume this is due to air in the lines.

I am concerned about causing damage by allowing the vibration to go on while bleeding the lines (assuming that air in the lines is the problem). So far I have kept the valves partially closed to reduce the loud noise and vibration. I would appreciate any assistance you can offer!

FYI, the house is a one level ranch built in 1993 and the toilets are of the style that use a floating ball to cut off the water flow.

Thanks!

Which ballcocks do you have? (see image). Let me know, Tom

Hello Tom,

I have the type in the right hand image. It looks like the problem has cleared up. Based on something's I read in the forum, I checked it again today and tried something a bit different. I let the tank start filling and got the knocking/vibration with the valve partially cracked open. However, as soon as I opened the cut off valve all the way the knocking went away. It appears that a big part of the problem was having the cut off valve open only part way. As of right now both toilets are functioning normally. I'll keep an eye on it to see if it stays fixed.

I do appreciate your jumping right in to see if you could help out. I expect I'll be back from time to time as I encounter more "new house experiences"!

No prob Stryger!
