It's really a very easy replacement. It takes about 5 minutes or less. See the you tube video http://www.youtube.com/watch?v=x_ePvpfAkAc. Note; replace the little washer on the top plastic screw as well as the big washer.

I don't know since I had a plumber do it. But it does come with clear directions. Plumber did it in 10 mins. If you're handy it should be easy.

I replaced this quite a while ago, but you should just be able to unscrew black nut that holds the green top part (that holds the gasket in place) very easily. And then just reverse the process. Take a look at some of the other reviews for some good pointers. Good luck.

The you tube video Ace referenced is good. Watch it first. Also agree that you should replace the small washer on the black plastic screw that holds it all together. Both come in the washer kit. My large gasket was blue same as the original... not red as in the video. I don't know what if any difference there is between the two colors.

The "unit" (the flush valve ball) simply unscrews. The gasket is sandwiched between the upper and lower halves.

It requires soldering - it's not a simple remove and replace. There are some YouTube videos out there, but unless you're very comfortable with soldering, suggest you buy a new unit.

First check if the sucked is the same side and model remove the old one before placing the order

make sure you have removed all the packaging, there maybe plastic wrap inside the unit that needs removed

Hi chris5969, as I installed mine, everything came to remove the old and replace with the new with no problems at all. I'm sure you'll do the same.

I was finding it impossible to unscrew the old filter, too. Then I tried putting the whole assembly in a bowl of hot water for a few minutes, and that did the trick! I also gently slid the edge of a thin spatula around the circle where the filter meets the housing, if that makes sense. Not sure if that did anything, but the warm bath definitely helped. I was thinking I'd have to trash it and replace the entire unit before I tried the hot water. Hope that helps.

Best thing to do is call ISSO at 800-777-7899. They may be able to replace the unit.

NO I agree with Fred buy the complete unit. In my case mine was old enough that they were not the same. Just write the color coded wire order before you remove them. Very easy to change.

No, I just unscrewed the old unit and screwed in the new one. I then plugged in the new unit and all worked well.

You will use the keypad to remove it. Go home and display senser. Put the I'd to do so.

Remove the one in the old one in the smoke box, and replace the new one using the existing screws. Just reverse how you remove it. It was a simple process.

yes, just give it a shot of liquid wrench before you remove the old one, clean well then replace.

if you have the new metal replacement part, you can disconnect the old plastic one by simply unthreading it completely off. Mine was broken off, but you should be able to get it off easily

Use the same connections and swap out, replacing one for one. Be SURE to have the fuse off. This could seriously take off a finger. It's not hard to do. Get yourself a blanket, crawl under the rig and pull off the old unit. ( Be sure your rig is supported to a point that it can't come down and crush you). Outside of safety precautions, this is easy!

I don't know, the unit is 'sealed'. If I can get it apart I will let you know.
