Rated 1 out of 5 by from Horrible Toilets Horrible product if I could give less stars I would. I have bought 3 of these toilets and were at the top end at home depot. The design is really terrible! I mean terrible! I have tried to adjust the toilets to ensure enough water was in the bowl but every time you go number 2 it just hits the porcelain, and you have to clean every time. I called Delta and they gave me the I'm sorry sir there is not much we can do. It would.be easier to just go and use a gallon of water and flush it myself. That's my two sense its frustrating when you spend 500-600 dollars on something a Home Depot bucket can do.

Rated 5 out of 5 by from Nice product Even though I just bought this toilet, I like it. It uses very little water but has great flushing. It also has normal features such as a normal flapper; so should I need to repair it, I can get a regular repair kit. The last toilet I bought from a different company had problems within months of buying it. The flapper was not sealing correctly but it was an abnormal flapper so that I could not buy a replacement! I'm glad I bought this Delta toilet.

Rated 5 out of 5 by from One of the better toilets I have ever bought This affordable toilet works very well, and much quieter than those with a Flushmate that scares our grandchildren with every flush. However, the handle requires a little more effort to flush than other toilets. That makes it somewhat harder for the relatives that are old and frail to flush. They have to put a little effort into flushing the handle.

Rated 5 out of 5 by from Delta Toilet Delight Got this as a replacement for a round seat. This was easy to install and the oval seat is much more comfortable. The packaging and contents made it an easy install. Flushes great and can already tell it's a water/money saver.

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!

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

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
