Poor water pressure in shower, wife not very happy.

[J&JD]

This morning, the first day of a month long adventure, the DW stepped out of the shower very unhappy with the water pressure. While trying the valve I noticed that there was good pressure on the hot side and almost no water coming out when turned to the cold side. When trying to mix the two the flow was anemic. Knowing that the trip would not be enjoyable with the shower in this condition I reluctantly took off the valve cover to see if I could fix the problem.

Behind the two set screws there are spring loaded rubber tipped flow regulators. The cold water one was frozen in the extended position limiting the flow. A little bit of lubricant and cleaning got everything loosened up and full water flow back to normal. I decided to post this after reading about this being a fairly often occurrence that often was hard to diagnose. This is on a 2017 Dutch Star with about 50k miles.

Nice job!

To add some more information, the shower valve is a Huntington Brass Model # 05120-00, discontinued. The regulators referred to are called Service Stops, Part # FA04120S. The Ceramic Disk Cartridge is part # ST7100. I had the same issue on our 2017 back in 2020 and researched all the information.

If I may ask, is the cartridge still available and are there any special instructions for replacing the cartridge? If parts are no longer available is there a plug & play complete valve assembly recommend?

I changed mine to a Moen early on. Best thing ever for the 2017 Ventana era. Huntington Brass was total crap. Not hard to change, just get the right config for shower, no tub.

It is. Just google ST7100 and several sources popup. I bought one back then and it sits on my shelf collecting dust.

Do you have a model # for the Moen that will cover the big rectangular hole in the wall?

 

[Neal]

The Moen is just the regulator, the item in your picture which goes through a plate. Can you show a picture of your setup with the wall plate installed?

This is what I believe I got, just the bottom part was installed.

Good Job, Jerry! Although it was probably more self preservation than anything.

I have the same model as Neal (we replaced ours at similar times) but have noticed that we need to turn the valve very far to the cold side to have it “warm”. I wonder if this valve has the same adjustments?

 

[Scotttkd2]

OP shows the mix valves (theirs was stuck) that allow you to customize the flow to your needs.

 

[J&JD]

Actually it wasn’t the mixing valve that was stuck it was the pressure/flow cold water plunger behind the set screw on the right. The one on the left is for the hot and was not stuck. No cold water could get to the mixing valve.

 

[Richpatty]

I may call Moen tomorrow and see what they say. Maybe they will send me a new cartridge.

 

[RKins]

I've had good luck calling Moen direct. When we got our coach it had top of the line Moen hardware (1997) in the kitchen and bath/shower. Unfortunately all the screens needed to be replaced and the screen in the kitchen pull-out spray faucet was not easy to find until I called Moen and they fixed me right up.

If I recall mine is like that too. It may have something to do with the actual water temp. I think you're in Florida so it's just below boiling I think Keep in mind fresh tank temp and also ground water temp.

 

[Richpatty]

LOL. I agree...Florida water is not refreshing. Especially when your water softener is sitting out there too. But we have seen this issue show up (at least somewhat) before arriving. Also, we would have to set the faucet to 3:00 to be able to stay in without it being too hot.

I did call Moen and they said temperature issues could be caused by the cartridge, so they are sending a new one. (under warranty).

Will let you know.

PS - We are back from Florida now...so once it arrives I can install it. Next trip out is not until June though.
