my delta one handle shower faucet

[ll1000a]

Installed new yet it drips when completely shut off but untwisting stips the drip (annoying) then after many uses sometimes the faucet get's stuck on. Then I find myself having to disassemble the unit to try to stop the drip.
Model#1348 bought from Home depot. Already saudered to tub pipes, so cannot return.
Is Delta crap? too much plastic and overseas parts?
Or Bad install on my part? it seemed simple, It should not leak

Delta is good.....

you probably got a solder ball into the mechanism....

and scarred up the o rings....


take it apart and blow water through the unit

to clear out anything inside the valve body



if that dont work , tha parts are free from Delta..

simply call them and ask for a whole new cartridge.....

Good idea, I've blown it out twice so I'll try delta. Also when I tightened the ring harder using a pipe wrench sealing the whole unit it does not get stuck 'on' but still drips from the spout. I have to untighten the 'knob' from the 'off' position to slow the drip. Pain...

Thanks for your input
