Low Water Pressure on the Hot Side Only? It Could Be Your Shower Cartridge

[@dannym5047]

Just finished replacing cartridge, what a wonderful success! Thanks

[@TopHomeowner]

Fantastic!

[@RandyLie]

Thanks for the video. I followed your instructions with my Hansgrohe system and replaced it with a new cartridge, but 2-months later the pressure has gradually worsened again. Any thoughts?

[@user-cj2wt2ku2g]

Probably the BEST DIY video regarding this concern. So straight forward and most of all...IT WORKED!

[@TopHomeowner]

Awesome! Glad it fixed your problem!

[@VolleyballJIM]

Yep, not too long, not too short, covered all topics

[@mikealvord55]

Change the cartridge same issue I did put it in upside down so right is on the hot side now. What are your thoughts?

[@djmannion2369]

Fixed the problem. Watched the video a few times and everything was SPOT ON!!! Two thumbs up!!! Thank you

[@TopHomeowner]

Great to hear!

[@deannabailey7408]

Great job describing the parts and how to...love to see any hiccups, because in the real world we always have issues, like the part not coming off easily. GREAT VIDEO!

[@TopHomeowner]

Thanks for watching... and for the feedback!

[@Salanan]

My hot water is suddenly low pressure at every faucet.

[@franklinrogers6388]

The issue where your pipe connects to your water heater, usually a clr type issue.

[@Zackmack91]

The issue is likely a blockage. Happens often with galvanized pipe not as common with copper.

[@jimjamjom1]

I have changed the complete shower unit (and therefore also the thermostat cartridge) and yet this exact problem persists (reduced pressure only on hot). Anyone got any thoughts about what else the problem could be?

[@aaronbaraiya3692]

any update? could be your water heater, do you have any issues with that?

[@joryclouthier]

If you are on a well with hard water or iron pipes hot water tank inlet/outlet could be blocking

[@MakaylaTW]

i’m having this problem too did you ever figure out a solution?

[@jimjamjom1]

@@MakaylaTW yes, for me it was the water tank in the attic was too small. Had to get someone in to work out the problem.

[@kia511]

The best video on the topic! Followed the instructions and have hot water pressure again! The strange thing is that my house is 8 years old and we have never used this guest shower, so not sure how the cartridge had gone bad?! Maybe from sitting there without water flowing through it?! Thanks again!

[@cabletv1997]

Thanks for sharing the video. Question. Could the low hot water pressure from the shower also affect the hot water pressure from the vanity sink faucet in the same bathroom?

[@ChuckTownRC51]

I did all this and it did nothing. Also, my water takes forever to get hot. This ONLY happens at one shower (and one place) in the entire house.

[@i-tit5474]

Try this: it's due to the air bubbles in the vertical pipe going to shower head and the sink is usually lower than shower head therefore it (the sink) gets more pressure .what i would do is either run the sink tap on full (Hot line) for a few seconds, you will hear air bubbles coming out once there is no bubbles you can turn it off or you can run both sink and shower ( on full hot lines as well) at the same time for a few second ( it may take longer depending on how far your hot water tank is to both) then turn off the sink tap. i hope that works let us know if it works for anyone. it works for me:)

[@flash8051]

At least a half dozen things that could make this task NOT go as easily as the video shows. Regardless, still helpful...just be aware that it may not be this easy (like most DIY projects).

[@gbpluspcrepair]

Agreed - with my luck, this is never going to be the fix! lol

[@anthonymadrigal8851]

Thanks for this video 👍 Really appreciate your work. thanks 🙏

[@kodaboda24]

What would be your course of action if this was happening to a shower that the hot water worked in the morning and now it’s not in the afternoon? Would you suspect a cartridge? Home is 20 years old, only this particular shower is loosing pressure on hot our other one is not. We do have polybutylene pipes.

[@truth6600]

Cartridge is pressure balancer, if you have a pressure drop it a no brainer.

[@TopHomeowner]

Most likely it's the cartridge.

[@truth6600]

I would suspect the cartridge, it floats between hot and cold,in the morning you shower relieving the hot expansion, during the day water heats up expands and gets stuck ,sometimes I have seen little or no pressure from both sides.

[@tomacquilano1304]

Brand new shower valve only delivering 2 GPM from the tub spout on full hot setting. Plumbing is all new as the bathroom was gutted and completely new mechanicals installed. The mixing valve is a Moen UT2133EPBN. On full cold from the tub spout I get just over 4 GPM. Spoke with Moen and they say it's not the valve. Any ideas? Thank You!

[@1smokeyj350]

I wouldn’t check the shower head if there’s pressure with the cold water

[@jacobsmith8644]

He said that

[@kaltrex9465]

Which point in the line to reduce water flow (pressure?) in the shower stream at least, to save money on water bill?

[@TopHomeowner]

They make shower heads that are designed to reduce the flow and save on water

[@knicks6030]

Quick question what is the pressure from the hot side is not only in the showers I have problems with foists as well.

[@jyt-iz6jm]

1st time someone tries this and half the cartridge gets stuck or breaks inside the valve. They will be calling a plumbing company. 2nd thing that occurs is the cheap aluminum puller breaks🤣🤣

[@bigboybelly1567]

I’m soooo glad I found this video, I could cry ugh

[@rscranman2002]

Nice video sir. Could this issue also occur in the bathroom faucet? Trickle of the hot water side comes out but nothing when we swing the lever to the cold water side. All other faucets/showers dispense water normally in house.

[@bethaiton9916]

Thanks! Your video helped me change my sister's cartridge. Thank you so much

[@TopHomeowner]

Thank you! Glad this was helpful!

[@timfalter5940]

Yeah the cartridge had nothing to do with mine... there is a mixing unit behind the cartridge that got clogged and had to be replaced. I then used the same cartridge.

[@jamesj4909]

Thanks for clear navigation through this repair. Worked a treat.

[@kanoelapriel8462]

Great video. How would I do this with a three knob shower set up?? Thanks in advance.

[@TopHomeowner]

With a three knob, there will be a separate valve on the hot side that's probably bad. Check out this video for more details: kzbin.info/www/bejne/sHW8Y4B5hr-Fn8U

[@davidanderson6304]

We have a moen brand faucet are the cartridges the same for all brands? Great video Thanks David Anderson Newell iowa

[@tonynguyen8248]

I have new one . I just put in today but the water not strong enough. Can you help me please tell me what I need to do?? Please

[@SteelCityFilms]

Hi, thanks for the great video. I get perfect cold but when turning to the hot it gets very weak. The entire system is brand new and has never been used before. I have the same set up in the other bath w/ no issues. I have a tankless heater (Navien NPE - 240S). I don't see or know about a manifold. Before buying the tool to remove the cartridge, do you have any suggestions? Much appreciated.

[@TopHomeowner]

Since it's new, you might just be able to use pliers to pull the cartridge out to inspect it without buying the tool. Also, it could be that the hot water line has some type of blockage inside the line... Like debris from wood or even solder if it's copper pipes. Either way, both hot and cold are mixed in the valve so if something is blocked, or if it's the cartridge, I'd look there first. If it's not the valve/cartridge, then the problem has to be between that shower and the hot water tank.

[@patdennis3202]

hey, i have the same tankless heater, same problem. Did you get it figured out?

[@truth6600]

Replace pressure balancer cartridge.

[@truth6600]

Great job.

[@MilkyWayGalaxyy]

Right after a water main break and repair on my block, my bathroom and kitchen sink hot water stopped coming out, only cold water comes out. But my shower and other bathroom sink are fine. Just my kitchen and main bathroom hot water stopped working at the same time and same day they worked on the main break on my block. So i doubt its the catridge, both faucets are only 6 years old. So is the problem with my hot water heater? But the hot water works for my shower and 2nd bathroom sink??

[@user-xh2iy1mw9r]

Would it be the valve if the hot water is low and the cold is full pressure but when it's hot the water also comes out of the faucet for the tub water?

[@lewishorn5628]

We had the same problem, replaced the cartridge and still have low hot water pressure in the shower. However, if the vanity sink water is running at the same time, there is good pressure. Any idea on what can cause this?

[@i-tit5474]

it's due to the air bubbles in the vertical pipe going to shower head and the sink is usually lower than shower head therefore it (the sink) gets more pressure .what i would do is either run the sink tap on full (Hot line) for a few seconds, you will hear air bubbles coming out once there is no bubbles you can turn it off or you can run both sink and shower ( on full hot lines as well) at the same time for a few second ( it may take longer depending on how far your hot water tank is to both) then turn off the sink tap. i hope that works let us know if it works for anyone. it works for me:)

[@AboveAllAerials]

@@i-tit5474 thank you soooooo much for this, I was just about to order a cartridge and saw your comment...after running both the hot water on the sink and shower the hot water pressure in the shower again is good again, you made my day! :)))))

[@fictions2135]

What if it’s the sink and shower only in one bathroom? Hot water in kitchen and second bathroom ok. Hot water in the sink and shower in the first bathroom very low. The only thing I can think is a bad solder job protruding into the copper pipe choking the flow.

[@PaulMathews-p4o]

That Pressure don't look too full :o

[@bee2333]

Behind the wall if i turn cold off from the valve and keep hot on i get no water on hot at all

[@stevenvillarreal683]

Same here. Any suggestions?

[@uncledoey]

thanks for this before/after presentation. One question--is there any way to tell whether the problem is just the cartridge as opposed to the whole valve fixture itself? The latter is a lot more work and mess.

[@tyoder87]

Great video. Fixed the issue but for some reason when the water is turned about halfway between cold and hot, it sounds like it’s struggling to to let water in or something. I heard an odd noise coming from it but only in between hot and cold. All the way either way there’s no noise. I got a Danco cartridge. Could it be just an inferior cartridge compared to the Moen?

[@David-ik6yu]

Great video. I just installed a new Moen 2510 valve with a new 1222 cartridge. I have extremely low water pressure. If I take the cartridge out and turn the house water back on, the water pressure is normal blowing across the shower. I have contacted Moen and their answer was a new 1222 cartridge. I have now swapped the cartridge 3 times with three different cartridges and no difference. I reversed the cartridge so that H&C are on the bottom. Same issue but now hot water comes out instead of cold. I did recently install a new hot water heater (electric) and pressure tank before replacing the shower valve. Could the pressure tank on the hot water heater be the issue???? All other plumbing in the house works fine.

[@TopHomeowner]

Both hot and cold are low pressure? Since it's fine everywhere else and you've swapped out the cartridge (a lot), I suppose it could be the valve itself but I'm not sure what the issue would be. Sorry I can't be more help.

[@David-ik6yu]

Thank you and sorry for the delayed reply. Ill advise if and when I figure it out.

[@HugeCockAndBalls]

I have the same issue! fuck moen!!!!

[@Mashataters]

@@David-ik6yu were you able to figure out what the issue was? I'm having the same problem

[@jeffmaraman8149]

Me too just the hot water. I've changed the cartridge and the seat several times...when I remove the seat and the cart water blasts out of the hole

[@OpenMindedForever]

For a rental unit built in 1928, where the hot water supply pipe is rusted and often clogged, which reduces the hot water flow rate (pressure), would you recommend (1) changing the pressure-balance mixing valve, (2) only the cartridge, and/or (3) "cold water backflushing" the hotline? I get fluctuating 0.05GPM to 1.5GPM hot water from my shower nipple and tub spout compared to 5.0GPM to 5.5GPM on the cold side. It can take 30 to 100 minutes to fill up a 50 gallon bathtub with hot water and I get thermal too-hot and too-cold shocks from the showerhead. Yikes! Old rusted pipes!

[@TopHomeowner]

Easiest would be to inspect the cartridge first and see if it has a problem, then I'd inspect inside the valve to see if theres some debris that can easily be removed. Good luck!

[@truth6600]

With a rental property, to remove liability, have the pipe replaced,if you take out the pressure balancer someone could get scalded.

[@thirteenthgrade508]

My issue is - mine is a tub/shower. The shower head is fine but the tub faucet when fully open on hot drops in water pressure. Brand new cartridge and shower a tub. Any ideas?

[@ferndogg4427]

Can u just turn off water through body valve?

[@TopHomeowner]

The cartridge is what blocks the water so once it's removed, you'll be soaked!

[@rjdatdude23]

That’s a nice shower

[@astrasasha]

So i have same shower setup and i had no pressure. But it was because of main valve wasn't fully opened. After opening it more, switching to shower water flow started making noise. Will be performing valve replacement anyways. Watched this video 5 times now.

[@jonymanay]

I only have low pressure on the hot water side. Having issues after replacing my shower head. So the hose and shower nozel part is new. I replaced the mixer last year so its brand new. Trying to think what i can do. I might try the old shower head back on after work.

[@cathyfrench325]

What if you replace the cartridge and still does not correct the hot water flow? Ie still low pressure

[@TopHomeowner]

Most likely there is something blocking the flow. Either something in the pipe (like solder/debris) or possibly a supply line valve is not open all the way

[@MicahsMom]

Ok so my husband replaced the cartdridge because we couuldnt het the water from the tub to stop dripping so he replaced it late night next moeming i went to take a shower turned cold water on from sjower then hot and not hot water turnung jt on only made the cold water slow down what did he do wrong

Would calcium deposits limit one or both hot and cold pressures? My shower upstairs doesn’t have as much cold water pressure but has plenty of hot It could easily be a cartridge issue but I’m gonna clean the deposits either way. I’ll also check the valves you mentioned

It's possible it's calcium, but that usually affects both hot and cold, not one or the other.
