Rated 3 out of 5 by from Disappointed Your site shows the cost of this faucet at over $400, the plummer provided your product and changed us over $600 for it and installation. I don't think it works any better than the less expensive options.

Rated 5 out of 5 by from Great Purchase Great product! Very good water flow. I like the 3 types of spray. Easy installation. Pleased with my purchase.

Rated 3 out of 5 by from Nothing special, This faucet is average nothing special about it. It looks good but needs more weight to draw the sprayer back to dock. The sprayer itself is kind of bulky to hold. The third function of the sprayer is pretty much useless(at least I have not found a use for that pattern). Would be nice to have the option of which side to have the on/off handle on. The supply lines could benefit by being more flexible. The durability and no leaks is most important to me and only time and use can answer those two things

Rated 1 out of 5 by from TERRIBLE FAUCET Purchased this faucet from HD two months ago and it keeps dripping. I move the handle around to try to find the "right spot" to stop the dripping and sometimes it works but most of the time it does not. The faucet is brand new so I should not be having any issues with it, right? WRONG!!! Honestly, I would like to exchange this faucet for a different type altogether but that would cost me about $500 for the faucet and a plumber to install it. Wish I never purchased this faucet. DO NOT PURCHASE!!! You will have nothing but headaches.

Rated 1 out of 5 by from Junk! Our faucet was purchased from HD, and within the first year, the magnetic mechanism broke twice. We had to replace the parts twice before finally after another “fight” and easily two hours on the telephone, they agreed to send a replacement faucet. They sent the wrong model and once again wasted more time on the phone with Delta. The supervisor we spoke with, was not very cordial and didn’t care how inconvenienced we were through this entire process. He couldn’t even schedule a home delivery pickup for the wrong faucet which was their fault! What kind of company does this???? In our opinion, his attitude and lack of regard to the paying customer was unacceptable and such that we will never buy another Delta product again. We also feel their quality has gone down hill like the customer service we received.

How can I change the water pressure of this faucet?

Asked by: blee72
Thank you for your question, blee72! The water flow on model 19978Z-SS-DST, is adjusted at the on/off handle. The spray pattern can be adjusted at the black button on the wand assembly. Model 19978Z-SS-DST has a maximum flow rate of 1.80 gpm @ 60 psi, and there is not a way to increase the maximum pressure. Best Regards, Benjamin

what is the difference between Model # 19978Z-SS-DST and Model # 9178-DST
