I have two Delta faucets in the bathroom that have a problem with the valves closing, shutting off the flow of water. The faucets are three years old and the problem first surfaced in the hot water side but now seems to occur with the cold water side as well. When turning on the hot water, the flow would be normal, but as the water warmed up, it seemed the valve slipped closed, restricting the water flow to a trickle. It now seems to be occurring on the cold water side as well. It seems that some O rings or something have gotten worn out. Am I on the right track, and if so, how difficult is the repair?

Go to delta website, take a picture of faucet with your cell phone and send. They should be able to identify and send you the parts. Meanwhile you'll have to turn water on and off from the emergency shut off valve under the sink. If it looks like the picture, it's probably the rubber seat and spring. If you don't want to wait go to your local "hardware" store. There may be someone there to help you. Bring the stem or cartridge, along with the rubber seat and spring. Don't use cold water while stem is removed. Turn cold off as well to prevent a mishap.
Your Delta faucet is open and close the valve very quick. This will produce back pressure on pipes. You need an anti water hammer / back pressure suppressor to avoid this problem. You can find it in local market.
These shut-off valves don't last long before they lock up. There is always the chance that they'll break. Go ahead and turn off the main water valve, then remove the packing nut (Google images for valve packing nut). This should allow you to turn the valve stem. However, you still run the risk of not being able to get to shut off. I almost always have to replace these shut-off valves whenever replacing a faucet anyway. So, assuming the valves are threaded on to the supply pipe (not soldered) then buy replacement valves as a very first step. I am assuming you won't want to do the soldered fitting yourself.
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.
There is a restriction in the faucet or the piping to the faucet on the hot wtaer side...this will be very hard to find and fix... The shower uses less water so it will get hot.... the tub spout allows more water flow so you cannot get the water more then warm...
Take the faucet apart and blow out all the passage ways with air... also run some water from the piping while the guts are out of the faucet, to flush the piping...
Hopefully this will fix you up...
Hi, W/D here.
Almost always, the shutoff valves are at the wall where water is supplied to the faucet. If the problem is with the drain piping, and the faucet valves don't leak, you don't have to shut off the water. Simply replace the drain piping and tighten it up. If you need any repair parts, you can get them from any hardware store. Please repost if there is anything else that I can help you with.
Good luck, and best regards,
Faucets in general operate either with a one handle valve stem or valve stems that uses small pieces of rubber to precent the water flow. In a single handle model this is usually caused by mineral deposits building up and the valve not being able to fully restrict the flow of water. The fix here is usually a new stem. On models that use a two handle system and do have replaceable valve stems one must get a repacement seat from a hadware store and reinstall the stem. In extreme cases the valve body may need to be ground internally and will require a professional. If you do not a have replaceable stems than the only alternative is a new faucet. I hope this assists you and thanks for using Fix Ya.
