Need to adjust the water stop for a delta monitor tub faucet with a Danco 10347 replacement cartridge.

we would need a little more information but sounds like it will need replacement, The water will eat up the meatle and make a rebuild impossible sorry but no quick fix the hot water lineis usley the culprit

the two screws are service stops open them all the way

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.

the cartridge inside is bad and needs to be replaced or at least cleaned in order to stop the water

Assuming that you have sufficient hot water, you need to adjust the Scald-Guard valve. It's usually quite easy to do. The intent is to limit the amount of hot water that can be fed to to shower head or tub spout. On the 1300/1400 series faucents there is a disk behind the faucet knob/lever called the rotational limit stop. Remove the knob/lever, either by popping the cover off the knob and removing the screw with a Philips head screw driver, or removing the handle with an allen wrench. Next adjust the rotational limit stop disk clockwise to increase the limit on hot water flow. Delta claims each tooth you click past clockwise will increase the maximum water temperature by 6 degrees F.

Delta has a great FAQ on their web site. As of Jan 30, 2011, this link is valid:

If the rotational limit stop disk is already turned to the maximum point (clockwise), then you may have a hot water flow problem (either with the cartridge or to or in the manifold). The cartridges require a little more know-how to replace. You'll need to shut off the main water valve prior to removing the old cartridge. There are a couple of places that detail how to replace and/or service the cartridges, including a short video on youtube. I can post more details on this if you find you need to replace the cartridge.

I'm not aware of any problems with non moen replacement parts being the cause for a water hammer problem. Start with the simplest and cheapest correction which is using a moen replacement cartridge. If the water hammer persists then you may have to install a water hammer arrester in the plumbing system. This is basically a shock absorber in the plumbing system to stop the effect of water hammer. An arrester will cost you around $10 to $15 at your local plumbing supply shop. If you are not comfortable soldering copper then you will want to hire a licensed plumber to complete the work for you.

I had the same type of problem with an older toilet in my house. It developed a water hammer when it shut off after filling the tank. I replaced the fill valve with a generic universal replacement for about $10 and it stopped. Again sometimes the simplest fix will work. Let me know how it works out.

While there are several cartridges that look similiar to what you have posted, Danco it self is an aftermarket parts replacement business. From my point of observation, your posted pic is of a Delta stem which visually has some distinctive attributes. Most every thing Danco makes is a copy or OEM replacement part packaged under their name.

You have to buy a Genuine Delta Part because Delta uses a proprietary quck connect fitting at the end of the hose.

You will need to turn of the water and remove the handle, then remove the large brass or chrome ring behind the center sleave that is behind the handle. now that ring is what holds the cartridge in the valve body, you will need to remove the cartridge the rubber seats and springs will both need to be changed ,you can buy a rebuild kit for this facuet, it has everything you need even the o rings you will find in there . Hope Ive Solved your problem! Thanks
