20 Most Recent Delta & Single Handle Shower Faucet Questions & Answers


The only possible explaination is that the water is finding it easier to go up than down. Water is lazy, just like me. ;)

Use an allen key to remove the tub spout. It's underneath and awkward. Once the allen key is loose, the spout just slides off. Try running the water. This may solve your problem and all you'll need is a new tub spout. If not.....

Turn the water off to the house.

Use an allen key to remove the handle.

Use a phillips to remove the trim plate (2 screws). Cut the silicone around the trim if it's there (which, in a proper installation it shouldn't be, but...)

Unscrew the nut (usually chrome) holding the cartridge into the brass body of the valve. The cartridge pulls straight out. Check for restriction in the ports of the cartridge itself. Check for restriction in the line going down to the tub spout. If you can't find anything, replace the cartridge.

Reassemble & Enjoy!

not all that familiar with your particular faucet. but in my experience, most plumbers dont put grease on the valves when installing them . the factory just uses enough grease to get the valve in the faucet. if you have extremely hot water and use it . it wont take to long for it to cause this problem.. just an opinion. i cant imagine how the buildings shutoff could have anything to do with your problem.

check the placement of the valve,, it may be 180 degrees out,, also,, try it with the shower head off, it may be clogged

easy way is to install a shutoff valve on the shower head.

If you look inside the shower head from the back where the threads are you can see a flow restrictor, if you take it out you get a lot better flow.

Look in where u screw the head on there should be a flow washer type thing u can take out or unscrew let me know if it works or you can find it

Was it hot enough before the Delta? If so open and close the hot water valve (under the sink) several times as there maybe mineral deposits. I know you said the flow is the same on hot and cold but unless your version is a single handle model the problem should lie with the valve. If this is a cartridge model (cold & Hot together) then the cartridge may be out of align allowing the cold and hot water to mix.

take the details to a plumber supply shop ( where the tradies get their parts ) and discuss the problem with them
it is very possible that there are other makes that will fit in the holes to replace the delta unit

should not be necessary to get behind the shower stall as there should be a hole big enough to remove /replace the facet insert
call a plumber in as it may be corroded in place and may require specialist tools for the job
get a quote first

Take handle off (either set-screw from side or bottom of handle, or phillips screw under cap on end of handle), pull off sleeve that's behind handle, unscrew nut that holds cartridge (strap wrench works great) and pull cartridge out.

there is probably a shutoff on the rough-in valve in the wall. Sometimes the seal in that comes apart and blocks the water. Get new stem for valve. Unscrew the nut, replace stem, tighten nut. Clean inside valve before u put new one in.

i would check the pipe going from the faucet to the showerhead for a clog

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:
http://www.deltafaucet.com/customersupport/faq/Water+Temperature/

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.

calcium build up "froze" the handle, would suggest immerse it in vinegar, or clr (do not know your local equvalent), or similar weak acid and leave for few minutes, run water through and then tap gently to try to dislodge it, repeat if necessary, and second time leave bit longer in acid.

i do not understand "handle leaks" - usually taps (faucets) do that... handle leak only if split or otherways physically damaged - it usually requires replacement, as handles are (including hose) extremely cheap and start with about $10.00 at any hardware store - i would not bother with repair - just replace.

another what can be wrong is seal gasket in handle mount. this cost few cents and is worth repairing... :-)

hope this will help you - do not forget to vote...
