SOURCE: How to Install Toilet

It's not terribly complicated, assuming that by "install a new toilet" you mean where there was alredy an existing toilet. First, remove the old toilet. Shut off the water supply valve, and flush the toilet. Then use a spone to get rid of the water that remains in the tank. Remove the nuts on the two bolts at the base of the toilet where the toilet meets the floor. These are usually hidden under two plastic caps. Now gently rock the toilet until it comes away from the floor. Get help to carry it out. Clean up the old wax that's around the flange where the pipe disappears into the floor. Don't be a wuss, it's only wax. Now you'll need the new toilet, a new supply line, new mounting bolts (don't reuse the old ones) and a two wax rings. Yes, I said two wax rings. You'll see why in a minute. Assemble the new toilet according to the instructions provided. Now here's a warning: Do NOT overtighten the bolts the hod the tank to the bowl. You're dealing with ceramics here, don't break them. Now, put the new hold-down bolts in place on the flange. Read the insturctions that came with the toilet, but you have to do this NOW. Now you'll need a helper. With the toilet upsided down, unwrap a wax ring. Make sure it's room temprature or it won't seal. Press the wax ring around the outlet flange on the base of the toilet. Now you and your helper carefully turn the toilet over without crushing the wax ring. Lift the toilet and slowly lowe it so the wax ring is centered over the "flange" which is where the sewer pipe goes into the foor. Then press the toilet firmly in place. Now if you're like most people, you screwed up here and crushed the wax ring without being centered on the flange. That's why I told you to buy two. Now you know what not to do, scrape off the first one and start again. When you've got the toilet sealed on the flange, connect and tighten the nuts on the bolts. Now you may have to use a hacksaw to cut off the remaining ends of the bolts so you can get the neat little plastic caps to fit. Now connect the water supply line. Now's where you start praying. Turn on the water and let the tank fill. Check the supply line for leaks. Fix as necessary. Now flush. Is water running out from around the base of the toilet? No? Good, you got a good seal. Yes? Very bad. Time to go back to the home center for yet another wax ring. Repeat the sealing process and get a good seal this time.

SOURCE: Toilet won't shut off

Does it leak from the overflow? If so then the washer at the top of the Fluidmaster needs to be replaced. If it is not going over the overflow then you will need to replace the flapper on the flush valve.

SOURCE: toilet cistern doesn't fill up

it sounds like one or more of your shut off valves has a glog from hard water calcium. were from indiana its a big problem here.To check this u will have to shut off main water supply and remove top of shut off valve and check for white crusty blockage, even if u see a few particals its present. It can severely restrict flow.

SOURCE: My Eljer toilet does not always flush completely.

Not being a plumber by trade I don't want to bad mouth what your plumber had to say but there may be other things to consider.
If the toilet does not flush directly into the main drain there is the possibilty that the coupling between the main drain and the toilet drain is under-sized which could cause reduced water flow and your toilet not flushing completely.

The dual flush cistern does not empty when the buttons are depressed. They have to be held down to clear the toilet bowl. How can I fix this?


cisterns never completely empty as the setting of the mechanism to close the valve is activated when it gets heavier than the water supporting it
try allowing more water into the cistern on a fill by adjusting the water level control
get a plumber in to clean out the sewerage pipes as there appears to be an obstruction in the line

Water flow from cistern does not shut off after the toilet in flushed


You need to get inside the cistern and see which type of shut off device you have. It will either be a long armed ball float or a short armed bobbin type. Ensure the float has not come away from the arm and that the adjustment is correct.

Hi i have a closed cistern on my toilet and the flush wasnt working! Eventually got lid off after much turmoil and flush works without lid but when lid is fastened on - it flushes but water keeps syphoning...


If water is constantly running into the cistern you will need to change the rubber washer in the shut-off valve. Washer kits are available from most DIY stores. Turn the water off at the isolating stop-****. Unscrew the end of the inlet valve (watch out that any springs etc. don't ping out) change teh washer and reassemble in reverse order.

When I flush the tank only half empties and not enough flushing action is the result as well as the bowl does not adequately fill after the flush.


Hi, if you remove the cistern lid and flush the toilet, look at the float (back left) to see if this is rising freely when the water fills back up. Once the water has stopped filling, check the fill level lines on the large syphon in the middle of cistern. Your model of toilet has an eco flush which will be lowest line to save water, so not as much water will flush out. There is a long plastic screw on the float (back left) which you can turn to adjust the water level to the higher line on syphon (1.6 gallon flush) and turn it slowley till the water level reaches that mark. flush a couple of times to see it is filling back up to the set amount.

Weak dual flush does not empty the toilet bowl.


well, yes... but apart from providing you with a forum in which to vent your frustration I'm not sure how you think we might help. I have the same problem with a dual flush cistern, but in my case I know that the root of the problem lies in the fact that the soil pipe leading from the bowl has insufficient fall (because the previous owner of my house moved the toilet further from the down pipe). Maybe something like this is contributing to your problem too?

Push button not operating fully/correctly. cistern flushes sometimes, but not always and is only two years old. It's a Grohe concealed cistern.


hey,
Check your button/s panel, check that the hoses are connected firmly.
Disconnect the hose and blow air through it, does it work now?
If it works ok, you need a new buttons panel. (or fix it).
If problem remains, you need to disassemble the pneumatic valve and check / clean/ repair it.
Look at this guide that might help you. though it is not the exact model, principle is the same.
Have fun
