Shower hot water side slow July 19, 2016, 02:03:16 pm I have noticed that the water flow is slower on the hot water side than the cold in the shower. It works OK. Kitchen and bathroom faucets seem to flow the same. Any ideas on what could cause that?Jim

Re: Shower hot water side slow Reply #3 – July 20, 2016, 09:02:33 am Jim,Have you taken the hot water valve apart? Either a restriction of some sort, or turning the knob is not fully raising the plug off the seat?Bill2003 23' FL

Re: Shower hot water side slow Reply #5 – July 20, 2016, 01:04:08 pm To Bill and Steve. I haven't tried to take the valve apart and it really doesn't look as though it can be taken apart. There are no screens on either the cold or hot side.I say that because about a year ago one side of the outside shower faucet failed and water started pouring out. I ended up removing the entire assembly and capping off the lines. All of it appeared to be cheap plastic and it didn't appear that it could be taken apart although I could certainly be wrong.The one thing that I could do is unscrew the hot water line from the back side of the connection to see if there is some debris but since it's output is acceptable I'm reluctant to do that for fear of creating a leak after putting back together.Given my experience with the failure of the outside shower controls I really must buy a replacement to have on hand should this one fail the same way. In the case of the shower it had probably been turned on only once or twice. We never hook up to city water without a pressure reducer and almost never hook up to city water anyway. And, if it fails you really can't use your water until fixed since there is no way to stop the flow to that fixture.On the plus side your questions got me looking at this closer and I learned I have a removable panel that exposes the bottom of the shower should I ever need to replace the drain.It seems logical that either there is a problem or debris at the hot water valve and I don't think the valve can be replaced by itself. 1 Likes

Re: Shower hot water side slow Reply #7 – July 20, 2016, 01:31:46 pm Jim,In the center of the knob on mine is a cap that I can pop off with a small screwdriver. Once it's out of the way, there's a phillips screw that you can remove to lift the knob out of the way. That should give you access to the valve body. Yours may be different than mine, but usually they can be worked on from the top. Bill 1 Likes

So once you have the knob removed what exactly can you do with the valve? ThanksJim
Re: Shower hot water side slow Reply #9 – July 20, 2016, 02:55:04 pm Jim,On mine, once the knob is off, there is a clear piece of plastic that fits into the white 'base' that pulls straight out. Once it's out of the way, it exposes a plastic hex 'lug' on the valve that can be used to turn it out. Taking it out on mine allows me to look into the back of the valve to see if there's any sort of obstruction in there, and also allows you to turn the stem with it out where you can see it to confirm it is moving in and out as it should.Hope this helps!Bill

I think that I will wait until I have a spare in hand and then take a look. I can't recall what mine looked like but I have to think it would be identical to yours.Jim
Re: Shower hot water side slow Reply #11 – July 21, 2016, 01:48:38 pm Bill, here are a couple of photos of the valve. I don't see anything that would be removable. Does this look like yours and, if so, what piece are you talking about removing? ThanksJim

Re: Shower hot water side slow Reply #13 – July 21, 2016, 06:22:20 pm Jim,It does look like mine except the outer piece on yours appears to be the same white plastic as the valve body, where mine is more opaque. I've attached, I hope, a couple of pictures of mine, one (fuzzy) with the outer sleeve on, and with it removed so you can see the hex lug on the valve stem. Good luck!Bill

In your earlier comment I understand you to say that once you remove that piece you can somehow remove the entire valve. Is that correct, and, if so, does it unscrew or pull out? Really appreciate your help.Jim

Re: Shower hot water side slow Reply #18 – July 21, 2016, 09:56:15 pm Jim, I replaced my shower faucet a few years ago when it spun, not sealing or opening fully - stripped internal nylon threads, I think. Removing and replacing the connector from the back was moderate difficulty because of poor finger strength, but was not technically hard. I removed the access panel behind the faucet, then unscrewed the connections. While I did not look at the inside of the faucet, I also had a problem with the bathroom sink faucet, wherein lime deposits had partially plugged a tiny screen system formed by holes in the nylon, up inside. The only way I could see them was to use a penlight, holding the faucet upside down in my hand.Vince at the mothership told me the valves were not removable/serviceable on my '08 MB. Perhaps other years or models have serviceable valves.Based on all that, I would suggest you try removing the connection behind the faucet to look for a restriction from debris or lime. Ken F in WY
Re: Shower hot water side slow Reply #19 – July 21, 2016, 11:13:05 pm Another thing to check, tho maybe it is unlikely with PEX, is a crimped hot water line feeding the shower valve - this happened with our '83, which used polybutylene tubing.Steve

I wouldn't be surprised if it was debris from the hot water tank since we spend a lot of time in the southwest. Despite using a water conditioner we still get deposits out of the tank.I hate unscrewing water lines, they just seem to insist on leaking when I screw them back together.Jim 1 Likes

Re: Shower hot water side slow Reply #23 – July 25, 2016, 08:18:57 pm I have had similar problems with my bathroom sink and shower faucet's and ended up replacing them. I am pretty sure the stuff that clogged them came from the hot water heater which we should flush periodically. I don't know if mine had ever been flushed until a few months ago but it had a huge amount of white stuff in it.
