Rated 5 out of 5 by from It pays to go with quality I purchased a less expensive toilet 7 years ago and recently discovered that the tank had cracked. Only one person in the house plus a new kitten who weighs about 3.5 lbs. I don't think he's responsible. Needless to say I was very disappointed. Happy that I bought a Delta -- great reputation. Porcelain is guaranteed for life!

Rated 1 out of 5 by from The Delta Foundations Elongated Toilet is TERRIBLE Long story short, the Delta Foundations Elongated Toilet is TERRIBLE, and I would NOT recommend it to anyone. I regret my decision to switch to this toilet, and should have stuck with the Kohler model elsewhere in my house. No matter what I have tried, this toilet consistently leaves streaks of fecal matter in the bowl after every use, and I need to manually brush and clean the bowl every time someone has a bowel movement (even an 8-year-old kid). I realize it's a low flush toilet at only 1.28 gallons per flush, but the problem with the toilet is the design and shape of the bowl, and not the quantity of water it uses. The shape of the bowl is such that fecal matter doesn't go to the bottom of the bowl where the water is, rather it sits on the porcelain or right at the edge of the water line. It doesn't clog, and the flush follows through just fine; it's just a poor design. It's embarrassing for us, for our guests, and it is NOT pleasant. All of the suggested "solutions" by Delta do not work, including: - Adjust the tank water level to match the waterline (correct at time of install) - Fully open the water supply shut-off valve (correct at time of install) - Clear obstructions from the trap way, jet, or bowl rim holes (there are no obstructions - water flows freely) - Clear obstructions from the waste line (there are no obstructions - water and waste flow freely) - Holding the lever longer to allow more water to flush (while an unacceptable "solution," it still does not help) If I can't find some way to recoup my money on this through Delta or Home Depot (though I can't imagine actually returning a toilet to the store), I'll be forced to put it out to the trash and lose the $130 I spent on it. I've only had it two weeks, and can't imagine living with it for years to come. I've never regretted a purchase or hated a product as much as I do this toilet - such a disappointment. It seems many many people are having the same issue, and I don't understand why the toilet has received some higher ratings. Save yourself the frustration and buy something else.

Rated 1 out of 5 by from Do not recommend! We just bought this toilet and installed it. Wish we did not! The design of the bowl is terrible! It requires multiple flushes for a bowel movement and will leave streaks every time!

Rated 5 out of 5 by from Initial problem with flush There seemed to be a problem where you need to flush 2 or 3 times to get rid of fecal matter. After leaving a negative review, I received an email from a Delta employee who suggested a fix. Thank you Jon, the fix worked and all is well.

how to adjust water level left in bowl after flush. (more)

Asked by: barbish
Hi, Barbish! Thank you for your question. While the Delta C43913-WH toilet is only designed to use 1.28 GPF (gallons per flush), you may also hold the flush lever down for a few seconds longer to allow for more water to flow through the tank into the bowl, which will help to clean the bowl and still conserve water, since older toilets were designed to use anywhere from 3-7 GPF. This will also allow for more water to stay into the bowl, the longer you hold the flush lever down. Best Regards, Rosanna

can this toilet be ordered with the flush lever on the opposite side?

Asked by: susan
Hello susan, Thank you for your question regarding the Delta Foundations® Elongated Toilet and I am happy to assist you today. Unfortunately, we do not manufacture this model with a right-hand lever option and I apologize for any inconvenience this may cause. If you are interested we do manufacture a dual flushing toilet which has 2 buttons located on the tank lid, model C43908D-WH. I hope this is helpful and again I am so sorry we do not offer a model with a lever located on the right although if we can assist you with anything else going forward, please do not hesitate to give us a call at 855-345-1345. Thank you, Brandy

What cleaning products does Delta approve for this model? I see that in-tank cleaners are highly discouraged, however; in the video I noticed that something colored the water blue to display the hydro flush technology.

Asked by: Lea29
Hi, Lea29! Thank you for your question. We do not recommend to use in-tank cleaners. Products containing chlorine or chlorine-related products can seriously damage fittings in the tank, which can cause leakage and property damage. Best Regards, Rosanna
