I have a shower valve body installed correctly, but no water gets to the shower spout. It seams as there is not enough pressure to make it. When I disassemble the tub, shower, and hot water 1/2" pipes and leave the cold pipe hooked up, water flows through valve just fine. Where is the pressure leak? Btw, the other baths work just fine. Is there a such thing as a valve that requires so much water pressure to work?

Plumber2011, is this a new install? Or problem that just started? What make and type of valve?

I first cut the copper lines in 3 places;hot,cold, and shower. Took out the old, went and bought a new Cadet Pressure Balancing bath and shower set. I then rebuilt the valve body assembly by connecting quick-connect compression fittings and also adding hot/cold shut offs for convenience. Once tubing was installed, I hooked only the cold water to the valve body to make sure water was getting through it. It done fine. So I fully installed the Cadet pieces and checked it and well, the problem. It's the second one I have tried. Any help?

Plumber2011, I'm guessing you need to adjust the hot limit stop, your installation instructions show how, check page three. Also look at cleaning cartridge, on page 4 good luck

Does the hot limit stop adjust the lack of pressure from cold water supply? Doesn't make sense to me. Can you explain the corralation between temperature and pressure and how it can regulate the cold pressure? Its also the second assembly I have purchased within 2 days of each other, doubting both cartridges would be obstructed. Thank you for your responses.

You obviously did something wrong during installation. What type/brand/model of the faucet is it ? Where is the diverter located ? Please, explain what is "shower spout" and where is it located ? Back to you... Milo

Diverter is a plumbing term I'm not familiar with, but if it's the valve body your talking about, its behind the esteuchon, above the tub spout, and below the shower spout which is attached to the showerhead on the tub side.

Showerhead is usually located 4-6 inches above the shower stall in the ones I have seen.

When i disassemble the tub, shower, and hot water 1/2" pipes and leave the cold pipe hooked up, water flows through valve just fine.

Plumber2011, I understood that your cold was flowing "just fine", is this correct?

Yes, with the cold line only hooked into valve and a bucket underneath, the water flowed fine through the valve out of the tub and shower outlets. But when I assemble all of the connections, water does not come out of showerhead and barely comes out of tub spout. There must be a technical reason with pressure somehow.

Hi Plumber2011...

You said, "Once tubing was installed, I hooked only the cold water to the valve body to make sure water was getting through it."

If the HOT water isn't hooked up or flowing properly to the valve you would not get cold water to flow properly when the valve is all hooked up, OK? Here, you have a temperature and PRESSURE balanced spool and if hot or cold isn't getting to the shower valve then you won't get water to flow from the shower when you assemble the valve entirely.

So, the big question is how is hot water flowing to the valve when you have the valve disassembled and hot water on? If it isn't flowing then that is the problem with the cold water... ;) Get hot water to flow full on and you should see the balance of water/pressure return to the valve.

Check that and get back to us, OK?

Thank you plumber2008 for your well informed answer concerning water pressure, you hit the nail on the head!
By knowing the type, make, and model of shower faucet, you were able to definatively explain why the lack of pressure without knowing the hot water heater was not in service yet. Temperature would not cause the lack of pressure and you did not straitly assume impropper assembly. The explanation of the lack of pressure equalibrium between cold and hot lines which must take place for the pressure balancing valve to work properly was grade A plumbing knowledge. Thank you for your response.

Plumber2011: Thank you for your negative feedback. Just trying to help...

When I asked you for the brand / type / model of your faucet, you got offended and slapped me with negative feedback. But then you proceed to post that same info right below my post for others to use in determining your plumbing problem. Also, it is not my fault you do not know what "diverter" is and that you used incorrect identification for shower arm. You should look it up in dictionary so you better understand your faucet and its parts before you start asking questions.

So the negative feedback you have left for my attempt to help you is plain wrong.

Furthermore, your logics in your conclusion is incorrect. Yes, Temperature Balancing device may, and will, inhibit water flow if not working properly. If the balancing mechanism gets stuck on one side, it prevents that side from delivering desirable volume of water through the body of the faucet.

Best Regards... Milo

Milo,
I started my test question with the given information of a correctly installed shower faucet. Your first response was to overlook the given information and criticize me with an assumption. You should have started with your answer by your question of type/make/model. You then asked me where the diverter is located which is a term only plumbers would be familiar with. The question included certain terms a common person would use to describe something he/she is not familiar with. As a plumber, you could have deduced that from the information given. The negative feedback was based on your criticism which is not advisable in the future questions to come. But I'm not here to interrupt your competition so I will select yes instead of no. I also chose no for parttime on his second answer because it was not an answer solving the problem question. He also asked a question that was directly answered in the test question. I chose yes on his first answer because although it did not solve the problem, it was instructions in a direction to at least try. By the way he stated his answer, I had confidence he was also doing his homework by reading instructions and relaying them. Furthermore, the additional information given outside the test question directly nulls your theory of my logics being incorrect. It specifically states that 2 faucets were tried and still the same problem. If one faucet was used only, then you could be correct, although that theory is very rare. Plumber2008 effectively used the information given and without criticism or assumption, gave instructions on how to proceed. I apologize for any inconvenience or illwill caused by this test question. I do hope we will become more professional in our dealings with others. Are you ready for problem 2? Just joking! Plumbers, pipe on.

Plumber2011..

Test question? Is that what all this is about... a test question?

If so, let me make a couple things clear, OK?

We do NOT answer test questions. It is one of the site rules... and you have just broken that rule and in a rude manner to boot!

Also, using negative feedback as you have... also against site rules. As you can see the negatives were removed as they were given for a ridiculous reason.

We are not here to answer to you or any silly games. We are all volunteers and take precious time from our days/nights to help people where we can, when we can. We do not appreciate having our time played with or having you treat it in such a trivial manner.

I would strongly advise you not to bother posting any more test questions or smartalec answers as they and you will be removed from the site on a permanent basis!

This is your first and only warning!

Mark
