Sounds like you might have the rubber cup seals installed upside down? The spring goes int he body first, then the cup seal goes over and on top of the spring.

Can't get the handle off the faucet hex won't budge

Don't even bother. I have 3 Delta shower faucets and have run into the same issue WITH ALL 3 .

Step 1: Call Delta and have them send you replacement parts before you follow the next step (Trim sleeve, cartridge, handle)

Step 2: HACKSAW just outside the handle, right through until it snaps off.
That's the only way you will be able to access the nut.

I tried eveything - Vinegar, WD40, CLR, Banging, Jiggling...

Problem: The brass nipple on the cartridge will fuse with the metal on the handle. Alternately, so does the Allen Key screw. They will not release no matter how hard you try.

I called Delta and they confirmed that the two metals will fuse together over time (a short period of time, in my case), but it's not a fault design but the water. Their solution (moving forward) is to wrap the brass nipple with Teflon Tape before attaching the handle, so that the 2 metals won't make contact.

However, one would think that Delta would rectify this issue. Say by enclosing a thin plastic cap that seats over the brass nipple, or better yet, pre-coat the inside of the handle themselves?

Regardless, don't expend too much energy. If you can't loosen anything,

We purchased a home built in 2001 that has the dual handle Delta Monitor 2300 series. Though this particular model, I believe, is designed to prevent this problem, my daughters are practically scalded...

There is probably mineral or rust deposits in the cartridge. Shut the water off and remove the handle and then the faceplate and remove the cartridges. Tap the cartridges and see if any debris comes out. You can try cleaning it out buy soaking it in a bowl of warm white vinegar. Keep moving it around and keep flushing the inside of the cartridge out and tapping it. There is usually a small check valve in the cartridge and you should here it rattle. With the cartridges out turn on the water supply for a few seconds to flush out the pipes. Then try reinstalling them or while they are out; go to your local plumbing supply or Home Depot or similar and purchase some replacement cartridges.

I have a Delta Tub/Spout Pull Down Diverter that has a pretty persistent drip. The HOT and COLD handles are turned off and seem to be as tight as they can be. After doing some research online I believe...

If your Delta RP17453 Pull-Down Diverter Tub Spout stops dripping after 5 minutes, your ok. If it never stops dripping, you need to replace delta faucet cartridge(s) behind the handle(s). This is were the water turns on and off and stops the water flow to the tub spout.

Delta faucets are some of the easiest to repair, and parts are usually available at any hardware store or home center. If you have a two handle faucet, replace both delta seats and springs and stems. If you have a single handle Delta faucet, replace the entire cartridge.

We have a Delta 172 single handle faucet. We had our hot water heater replaced. Now it takes longer for hot water to get to the faucet. Could debris (calcium build up, etc.) from the replacement get in...

Yes, debris from water heater replacements often breaks lose and gets stuck. The problem could potentially be anywhere between water heater and the faucet. The faucets shut off valves or the Delta faucet cartridge itself. Turn the hot and cold water valves off under the sink and disconnect the water supply lines from the faucet. aim the water supply lines into a bucket and turn the valves on one at a time. If there is a significant reduction in the water pressure and volume on the hot water side, you need to replace the shut off valve. If there is no reduction in water pressure, you need to clean and/or replace the Delta faucet cartridge. Contact Delta to receive free replacement parts.

Water is not very hot.

First try adjusting the pressure balancing gear located right behind the handle. If you still do not have hot water I suggest to replace the cartridge.

2-handle faucet handles both rotate "on" counter=clockwise

Here's the solution from Delta:
On a two-handle kitchen or lavatory faucet, if the handles rotate in the wrong direction, simply rotate the right stem stop assembly 180 degrees. This will change the rotation of the handle to the other direction.

I installed Delta shower faucet 132900 and I could not shut the water. What did I do wrong?

Did you solder the valve in? If so you may have got it to hot. Or debris could have gotten in the valve. Turn the water off, remove the handle and cartridge. Check cartridge for damage or debris
