 water flows from tub and shower
Author: blackxacto (TN)

Two handled water facet in the tub which is in my house that is appx 60 years old. Problem is that when I turn on the water faucets to fill the tub, water comes out the shower head. I replaced the tub water spout/divertor. Water still flows out the shower head, unwanted, when filing tub. My plumber says that I have too high water pressure for the two handle faucet. Does this sound correct? She recommends adding a third divertor handle to the tub. I have the wall removed from behind the tub, as the drain and stopper assembly was just replaced. Should I have to spend another $250 to correct the showerhead flow, or is there an cheaper/easier way to lower the pressure to the tub faucets. I will do what I have to, but was just checking w you guy's for any insight. Thanks

PS: or should I just live with it, I mean all the water goes into the tub anyway, just hits my head sometimes.

Not likely, but since you have a two handled faucet, it would either have to have a "restrictor" inside the valve or use a "twin ell" at the spout. Without seeing your installation, I cannot tell if you have either of these. IF the shower was just added to an existing installation, it is very possible that you have neither.

Did your plumber happen to test the pressure and tell you what it was? If you are on city water and your pressure is above 80 psi, I would advise you to have a pressure reducing valve installed. If you have one I would have it replaced if the pressure can not be adjusted. This would lower the incoming water pressure to your whole home.

does the water flow from the showerhead with the spout removed?

Save your money and purchase a showerhead with a shutoff or you can use your present showerhead with a shutoff adapter. They are available with lever or push button operater.

You'll have to decide if you can "live with it" or not.

Since you have the wall open you could install a "Twin Ell"

Would you describe where this unit goes in the tub plumbing lines? What does it do? Thank you very much for your response.

Where would the "restrictor" go? Is it inserted on both valves somehow? Thanks for your response.

one pipe goes from the valve to the "front" opening. The rear opening is connected to the shower riser, and 3/4" diverter spout is connected to the front opening.

No have not tested as yet. Still not sure what my next move should be. See the link in my original message for a picture of the tub piping. Thank you.

If I unscrew the tub water spout completely off, turn both hot or cold water valves ON, or only one valve, there is no water running from the shower head above.

If I screw the tub spout BACK ON, and turn on both water valves or even one of the valves, I get water coming out of the showerhead spout, with the shower head off or screwed back on.

It's like with water valves turned on, the tub spout restricts the water flow backing it up out of the showerhead. The tub spout is new? I just bought it. Why would a spout restrict water flow into a tub? Only my naive opinion, but isn't the idea to fill the tub asap?

The easiest fix would be to go with Wheelchair's recommendation for the shower head that shuts off.

The first thing I would try would be to remove the elbow and the two galvanized pieces going to the tub spout. They are probably very corroded and causing back-pressure, thus forcing water to come out of the shower head. Replace them with brass.

"replace them with brass." (or copper)

Unfortuately, we cannot tell if there is a restrictor in the valve at the point where the shower riser is connected, but your description of the problem indicates that it was a tub filler OR shower valve, NOT a tub filler AND shower valve, and someone just connected the shower riser to the valve. If that is the case, and it probably is, then you DO need the twin ell shown previously.

It doesn't GO anywhere since it is installed by the manufacturer and you CANNOT retrofit one into the valve.

The spout does NOT "restrict" the flow into the tub, but it does introduce "backpressure" which is what causes your problem.

And once they are removed, replace the elbow with a twin ell, remove the shower riser from the top of the valve and connect it to the rear opening of the twin ell, then install a 3/4" nipple and a 3/4" diverter spout. IF there were a restrictor in the valve, it would be more likely to REDUCE the flow to the spout, NOT increase it to cause the problem.
