Last week I installed a tub and shower and replaced the shower valve. The valve was a Delta rough in I think 10000 series. The problem I have is when you turn on the valve a slight trickel come out the shower head. HO does not like the trickle. I have replaced the cartridge and still a trickle.

I have had this before but the HO was flipping the house and didn't care.

The Delta rep has no ideas. Water pressure is 45 psi

I'm guessing you meant when you turn off the valve there is a slight trickle from the shower head?

 

[smythers1968]

No, I stated it correctly when you turn on the valve without the diverter pulled, water come out the shower head

 

[Optimus Primer]

is that the cartridge that has o-rings on the back of it? if so then one might be ripped or missing. If the water comes out pretty good, the valve may be upside down.

What kind of piping to the valve, to the diverter spout?

 

[smythers1968]

1/2" pex

on the diverter and the shower riser:blink:?

 

[Protech]

could be a restricted tub spout or the line that feeds it.

 

[smythers1968]

1/2" pet to the valve out of the valve to the shower head and diverter.
Removed the diverter and still water out of head

 

[Optimus Primer]

how much water? you say you removed the divertor, did you cap the line?

 

[uaplumber]

Scored valve body?

 

[smythers1968]

How much water? Well a strong trickle.

I took off the divert/tub spout thinking that it was the restriction but still have water out the shower head.

Could it be a bad rough in valve?

 

[Protech]

could the valve be roughed in sideways? that is rotated by 90 degrees.

 

[Optimus Primer]

I don't know. If you're sure there are no washers missing or ripped. I know if the valve is upside down you will get water out of both at the same time.

I had the same problem, most valve directions state copper from valve to tub spout. Pex gives too much restriction. my valve was a Kohler. learned my lesson, we fixed it with a chrome shut off at the shower head

 

[uaplumber]

The R10000 rough-in has a notch for the cartridge to keep it from being installed wrong. Check the body for damage.

 

[Optimus Primer]

I'm talking about the actual valve being installed upside down.

 

[smythers1968]

As a young apprentice I installed a valve upside down. Boss made me tear it out after hours and off the clock. Hard lesson. I know the valve is installed correctly. I.m thinking the pex is causing the issue

 

[uaplumber]

Check to be sure that the "H" is on the left side when the Cartridge is installed.

 

[Optimus Primer]

ok don't know. we use copper or cpvc. correction. not cpvc to tub spout. copper only. I was just saying we use only the 2 for water piping.
