That “oh shit” at 3:56 was so relatable to 99% of home repairs or vehicle projects I do. Great video!

[@weekendhomeprojects]

Haha thanks

[@hartleyhubbard3827]

lol.... this is what I appreciate about "youtubers", they, for the most part, don't edit out the mistakes that happen to them. Thanks for posting this - I'm installing my first dual flush gasket right now. Greg [garden grove, CA usa]

[@aimeekamat2312]

Thank you!!!! Just cleaned the seal really well and put it in flipped to the other side. Saved over 300 for a plumber's visit!!!!!

[@lipingma]

Great DIY video. Has the right information, and the information any DIYer that might need to complete this task!

[@weekendhomeprojects]

Thank you. :)

corkys dual flush kit worked perfectly, thank you for the great video.

Thanks for posting. I had no clue how to get it apart, thanks for showing us!

[@weekendhomeprojects]

Glad it helped

[@amielynnhicks8376]

Thank you so much for posting this video and helps 100%

[@TheKMJ03]

Thank you for posting this video! I was able to fix the toilet in about 10 minutes (took me a bit to pry off the old seal). Again, thank you for sharing this video, you saved me from a lot of unnecessary stress and headaches!

[@weekendhomeprojects]

Awesome! Glad it helped.

[@cyberpunkr1531]

Excellent attention to detail, helped so much, thank you!

[@brianspivey9254]

Thanks so much, I was getting ready to call American Home Shield, to repair this and I did it in 5 minutes!!

[@weekendhomeprojects]

Awesome! Did you just replace the seal or the canister too?

Thanks for those video. It’s just what I was looking for!

[@weekendhomeprojects]

Glad it helped.

[@MrTampadan]

Great self help. Gave me the confidence to twist and pull. Did also notice blue on left, on right after reassembly, check that water bill!

[@TEverettReynolds]

Yes indeed, I had no fucking clue how to get it apart...

[@dgott7726]

I found the correct seal for my Glacier Bay N2316T toilet at Home Depot....Fluidmaster 83SGB. Internals look like the ones in this video. Fluidmaster seal fit perfectly.

[@kam20u-zj2qr]

Thanks for the good video

[@weekendhomeprojects]

You’re welcome :)

[@quietstormssvereen6582]

I did find korky brand gasket however home depot carried FLUIDMASTER Dual Flush Valve Seal Specifically for GLACIER BAY COMES WITH TWO DIFFERENT SIZE SEALS ONE FOR WHITE VALVE, 1 FOR BLACK VALVE. WORKED PERFECTLY

[@richardgermain8018]

thanx for the video. Not sure how we are supposed to know how to fix the darn thing. Did toilets used to come with manuals or something?

[@motoman9944]

Is the seal still working? I think there's another seal at the base (beneath the one you replaced). I was going to replace that one, but can't get it out.

[@MrJoelmur]

Thanks for this. Couldn't figure out how to get the flush cartridge out so that i could get the baking soda and vinegar down the main outlet. Scaly buildup in the tank caused clogs in the jets. Flushing like new now. Thanks!

[@weekendhomeprojects]

Glad it helped. And great idea on cleaning, hadn't thought of that.

[@louiserowley-spendlove2462]

Did you get yours fixed?

Excelente, aunque fué en ingles, que no hablo, entendí, perfectamente, gracias

[@weekendhomeprojects]

¡Impresionante! Me alegro de que haya ayudado.

[@IvanRossS]

Just flip your gasket :) I found a small tear on the gasket. So I just flipped it. Working perfectly now. My gasket is really soft silicone not rubber. If you have a rubber gasket is probably really hard by now and at that point you need to replace it.

[@weekendhomeprojects]

Good tip!

[@kimmcamp]

Question. My toilet tank isn't filling up, and the water keeps running. I have replaced the fill valve, would replacing the flush seal work?

[@tonymaxwellhatt1175]

What about the base unit that the flush unit sits on? That base unit has a thick, black rubber seal. Can you also get a leak if that black rubber seal gets worn?

[@alexthatcher7204]

How to I increase the water in the tank and/or water in toilet??

[@cyndyreynolds4068]

I replaced seal I bought at home depot for the glacier bay. It was not exactly the same size and it did not fix the problem 😢

[@HoangNguyen-fm6nd]

And did this replacement as well. And still a small leak. I’m doing the food color test. It’s an American standard dual flush

[@weekendhomeprojects]

I still had a small leak too, and bought a replacement canister. Still needing to put it in, but oddly, haven't heard it refilling in a couple months. So I've not been in a hurry.

[@swamisrinivasan1893]

what is size of seal how you kept spare without removing one in service

[@normjones6916]

flush valve needs vaseline to slide properly up and down with older ring, newer rings are too tight and get stuck, any ideas ? Yhanks

[@sammitchell5942]

I can’t find the video on the complete replacement of the flush valve. I have a similar problem with my Kohler one piece flush valve. Have no idea how to remove the old one lol. Hope the new one I ordered comes with instructions

[@weekendhomeprojects]

I’ve not installed mine yet. May do it this weekend.

[@sammitchell5942]

I replaced it. Very easy. Just unscrew the base counter clockwise and it will pop out. Unfortunately for me it’s the same problem leaking. Talked to supplier and is making arrangements to call me back with a solution to the leak. Assuming it’s an easy fix I hope. I’ll let you know

[@ankitchapagain4477]

Design is similar to our home toilet

[@albyjam]

Okay, plumber installed all new float valve and dual flush plunger valve, seal, bolts and washers. Now, almost every hour or two, the toilet fills for a few seconds. No exterior leaks. I dont know if its bad parts, or one of many adjustments needed on one of the parts. How does one isolate the problem?

[@weekendhomeprojects]

Sorry, just saw this message. Did you end up figuring out the problem? My guess is bad parts or bad install. If it's loosing water then it's getting around the seal somehow, either the seal is damaged or not seated properly.

[@hugthynug4081]

thanks dad

[@weekendhomeprojects]

Did your mom work in a bar in Panama City in late 2001? If so, you're welcome son. Hope you're doing well.

@@weekendhomeprojects unfortunately not

[@jara20001]

You left the flush panels on the wrong sides. Blue to the left, white to the right... you get two turds for that !.

[@weekendhomeprojects]

Good eye. I’ll take those turds good sir.

[@Pullingguard79]

I've replaced the seal, but toilet keeps running. I'm guessing I have to replace the whole cannister?

[@weekendhomeprojects]

Yes. I’m in the same boat. Had the canister sitting around for 4 months waiting to install haha. Video coming……soon…ish

[@JM_Studios]

I changed the seal and still nothing.. any other options or something I can do to stop the slow leak?

[@weekendhomeprojects]

Change out the canister. They sell them at Lowe’s / Home Depot. I bought one but haven’t installed it yet.

[@JM_Studios]

@@weekendhomeprojects thanks! That was my next option. Appreciate ur vids!

[@cheyennerafterq]

Yep, home stores suck when it comes to anything plumbing, and what they do carry are lower quality than what you can get from a good plumbing supply house.

[@weekendhomeprojects]

Good suggestion.

[@tijger11]

Did u noticed during the re-install its 180 degrees wrong (take out = Blue left side / Re-install = Blue right side)

[@weekendhomeprojects]

Good catch. I didn’t notice.

[@TsheegeNtsoane]

I've replaced the seal but the toilet is leaking

[@weekendhomeprojects]

You’ll have to replace the entire canister

[@PoppinWheeliez]

Yeah......I am slowly transitioning back to traditional appliances and tried and true designs. I junked my front load washer and dryer already. Went commercial top load all metal, stainless tub. No stink, better wash. Toilet, will be heading back to a flapper flush style after the cartridge system has failed again. Dual flush toilet costing money. Not saving it. 💰 🗑 🚮 😢
