No they are not all the same.
not all toilet bowls and tanks are compatible. If your toilet bowl has no holes for a tank it most likely a bowl that is made for a flush valve, or a high or low boy mounted tank.
A toilet tank made by a different brand may not fit properly, so it is better to get the same brand.
This depends on whether you have a low level toilet or a close coupled toilet. But none the less, its all the same in the end. Take the tank off completely and underneath will be a big nut, take it off using gas pliers, replace the gasket, put the big nut back on, tighten, but ever so much, place the tank back and there you go.
You should be able to take the old tank off and mesure the distance of the mounting bolt holes and mesure the diamiter of the water hole then go to home depot and mesure some of the tanks they have. I diagree with the previous answer. By the way, it's spelled: measure. Anyway, if you have a 1.6 gallon toilet tank, you should replace it with the same brand. Different manufacturers tanks will NOT work with just any toilet. If you have the old style toilet e.g. 3.5 to 5.0 gallon tank, you would have to find a junk dealer who would have the exact same type of tank.
This all depends on the condition of the septic tank. Its like asking, how long is a piece of string
It all goes to the same treatment plant and is sent down stream to the next town or city. All tap water is the same, sink or toilet.
no
Mine has neither and it works perfectly I install this type all the time
Certainly, as long as, all the solids are removed during the flush.
the rubber tank seal (bowl to tank) didnt seat correctly
If the toilet bowl fills lower than the previous waterline, the tank may not be working properly. Check that the float is moving freely and allowing the tank to refill all the way. Also make sure the filler tube is filling the toilet and is not directed elsewhere.
Toilet flaps are easy to change , just bend the ears around the handles and undo the chain to the flush handle then install a new one the same way. If you want to change the plastic or brass over flow tube assembly then it can be a little difficult. 1 shut off the toilet stop. 2 flush the toilet and hold the flush valve open so it drains most of the water. 3 unscrew the toilet supply nut ( water will spill out from inside the ballcock). 4 vacuum out the tank so its dry and then unscrew the 2 or 3 tank bolts . 5 pull the tank then unscrew the big nut on the over flow. 6 put a bead of silicon on your new toilet over flow rubber gasket then install it and tighten the nut, then do all the steps backwards and when you put your toilet tank bolts back in just for safety put a bead of silicon on your toilet tank bolt rubber washers and you shouldn't have any problems with any leaks.
