How do I replace a toilet seat on duravit happy D toilet

Remove and clean the flush valve and the flush valve seat(it is the flap that opens up to allow water to flush the toilet). Once the edges of the valve and the seat are cleaned, possibly with "0000" grit bulldog steel wool, it should not leak anymore. To make sure it is not leaking, once tank has refilled completely, put some food die in the tank. If, after 10-15 minutes, the water in the toilet bowl is colored, you have a leak from the flush valve. Replacing the flush valve is very easy - just bring the old one with you to the hardware/plumbing store and ask for a replacement. Blessings and good luck!!

Make sure your new flapper is the same as the old one and replace the new one the same way you removed the old one.

Try using brass bolts instead of plastic ones

I’m happy to help further over the phone at https://www.6ya.com/expert/robert_24775b73ca70da93

you can get replacement screws at home depot or lowes if the hinge is broken you need to replace the seat

Are the install correct ?I can't believe an install time frame where the technician is actually on time! Work was done quickly and efficiently. Definitely one of the best install experience I've had. Thank You.

I have not been able to find a "tribeca" on the Duravit website but on the site of one of their parts distributors I found the Duravit Toilet Seat DUR 006331000. Is this your model? Starck 3

On the Duravit website this product looks very similar but not the same number.

I was not able to find replacement hinges for this model sold separately. You might consider using their Find a Retailer feature to find an outlet close to you where you might make inquiries or order hinges and/or a new lid.

A fairly easy ( but messy ) fix - get a replacement tank to bowl gasket and bolt kit, shut off water supply, drain tank, remove bolts ( you might have to cut, depending on your water source and minerals in your water). Remove old gasket and clean surface with 00 grade steel wool. Replace gasket, install new bolts, remount tank.
Good luck!!

Unfortunately you won't find a universal replacement part to work with this seat which you would commonly find at your local hardware store. I've looked through the Durovit site and could not find a parts catalog. Try using the find retailer option on the manufacturers site and if there isn't a retailer in your area contact the manufacturer directly to see if they supply parts for their seats. I'm guessing they don't and you would likely have to purchase a new seat.

The push button siphon assembly is worn out. Just replace it entirely.

You need an open end wrench or socket I believe 9/16 is the size
