- Is your mixer shower water COLD ?
Here I show how to fit a NEW Thermostatic Shower Cartridge for a Bristan PRISM Mixer shower. Although this is for a Bristan Prism shower, the process is much the same for most Thermostatic valves. (Links to all tools and items used are in the description below)
The cartridge featured in this video is PART NUMBER - CART 06734B (Non threaded version) which is suitable for the Bristan PRISM Mixer shower.
Part numbers and items will vary depending on the type of mixer shower that you have, so please check to ensure that you purchase the correct shower valve / shower cartridge for your particular shower.
This video shows you how to replace the thermostatic cartridge within the mixer shower. This is the part required when your mixer shower fails to provide hot water. This is a common fault but fitting a new thermostatic cartridge / valve will instantly fix the problem.

Hi.. are there any alternate multipurpose silicon grease... the one you showed is not available
@@ateek66 Hi, This one will do the same job amzn.to/2ZLTr9c
Hi, thanks for the video. What is the model of this Bristan shower? I’m currently having a problem with it leaking and no hot water and the plumber says I need a new flow cartridge and temperature cartridge. Thanks
@@jwlcham Hi, It is a Bristan PRISM shower, hope this helps ?
This is great content for single woman sick of men telling me the whole shower panel needs replacing
Thanks Jay, I am glad you found it helpful, thanks for the comment !
Your problem with men have nothing to do with the shower mixer love, the shower mixer is just an excuse to trash talk men😅
Thanks for the video, which helped me replacing the on/off and Thermostatic valves on my Bristan Quadrant shower. Both had failed after 20 years of daily use. Luckily found replacement parts from Di Vapor, as the Bristan Quadrant range is no longer in production. Suggest using a 30mm box spanner to remove the thermostatic value retaining nut, because there is not much of the hex surface to get a grip on. Also used a lime scale cleaner (ensure you flush with clean water afterwards) internal to the valves as a bit of a mess. Thanks again.
No problem, glad you found the video useful Martin !
Thanks Mate, just what I needed
No problem, glad it was helpful
Brilliant video and exactly what I’m looking for to replace the same thermostat. I assume this is a Scotia build as everything looks the same. Can I ask the best way to isolate the hot water supply to replace the thermostat? (Boulter Buderus oil boiler and hot water tank). I know mains supply is under utility sink. Thanks
Thanks, yes, I think this was indeed a Scotia home :-) Best to look for an isolation valve coming from your hot water tank, you should be able to find that no problem. Thanks for the comment
Great vid
Thanks Mo ! 👍
Great explanatory video.
My problem with this same shower is tiny holes in the shower wall outlet metal dome and water sprays out. Probably due to corrosion as I am near Aberdeen beach.
How can I remove the outlet & is there a straight replacement?
Cheers!
Hi, it is difficult to say without seeing it but if it is corroded, best practice to replace the whole unit as you don't want to risk a leak when you are not in your property.
A good clear video. I need to do this with my old Trevi Therm 300. Do you know if it is the same procedure? There is a part called 'calibration control' between the knob and the cartridge.
I am not familiar with the Trevi Therm 300, so cannot comment on that. The calibration control will just be water temperature setting, it is usual to set this to around 38 degrees c.
Excellent info. I have problem my control knob will not pull off after grub screw is removed any ideas Andrew . Ok small hammer and chisel to price off did if thanks
Thanks Andrew. If the control knob is stuck, you are best to squirt in a releasing agent such as WD40 or PLUSGAS - try to prize it away a little bit and then squirt loads of releasing agent in and leave for a good 5-10 minutes. That might work, try to avoid using a hammer and chisel 😂💪👍
@@Bacrenfencing Hi thanks for replying. Sorry after lots of releasing fluid still had to resort to a small hammer and chisel. Andrew
@@andrewfowler267 Did you get it off Andrew ?
This video was really helpful - thank you. For some reason I just have Hot water - any idea what I missed when replacing the parts please?
Thanks, I'm not sure why you would just have hot water after replacing the valve ?
@@Bacrenfencing Thank you - could it be that I replaced the black rubber piece the wrong way?
The cartridge wasn't secured tightly enough - it wasn't flush with the silver water control !!!
@@elicastelli9728 That's good you got it sorted !
This is a great video! Many thanks! I need to replace the Thermostatic cartridge on my shower as there is no variation of temperature. It's either mildy hot when on max or cold in any other direction. The shower set up is the same as your video i.e. temperature handle at the bottom and pressure handle at the top, built into the wall. However, plumbers are telling me they are not able to do it unless they know the manfufacturer of the shower. Is there no way around this? E.g. universal parts, if I take the existing valve to a plumbers merchant? The shower was installed 10 years prior to me moving into the proeprty so I have no access to the manfuacturer details and it's frustrating, given how simple the fix is. All the best, Nick
Take the valve out and take it to the plumbers merchant, they will be able to find a replacement I am sure. There is probably a serial number on the cartridge which will help identify it. Plumbers will often say that because it can be a lot of hassle getting the correct replacement parts and will cost plumbers time and money - can't blame them for that.
@@Bacrenfencing this is great. Many thanks!
Have you got a similar video or can you advise regarding the top valve (water flow) as my shower is dripping.
Thank you.
John
Sorry John, I have not got a video on that,
My shower cartridge just came flying out and gushing water. The collar was held in with a small Allen wrench screw but there was no threaded ring for it to fit into the hold. It seemed so unusual.
All showers are different, this was for a Bristan PRISM shower.
Hello, very informative video, i tried to follow the same procedure myself :-) ...i manage to spray wd40 and the hexagonal nut opened quite nicely , however the cartridge is not coming out as in your video. It seems there is no spring in it. The model is Bristan Qube , part is 00622415. How do i take this cartridge out please ? Also, how do i calibrate the temperature. Thank you.
I have no experience with the Qube but I would assume that the cartridge should just pull out. Try praying some releasing agent and pulling it out gently with a set of grips. In order to correctly calibrate the temperature, you would need a water temperature thermometer to determine the temp. These should be factory set at around 38 degrees, so I always mark it before moving anything and then replace exactly in the same position.
@@Bacrenfencing Thanks. I will try once again. It’s called screw in cartridge it seems, so wondering if it has no spring but instead I have to further unscrew the cartridge after I have taken the hexagonal nut out. I am looking to call Bristan service Center tomorrow so hopefully will have it sorted.
@@guptanaveeen Please let me know how you get on, hopefully you will get it sorted !
Thanks for the video. Unfortunately I don’t manage to remove the nut. I’ve trie spraying WD40 several times. Any recommendation?
Try heating the nut with a small blow torch but obviously be very careful - only do that if you are confident. Failing that, best to call a plumber to do it for you.
@@Bacrenfencing Thanks for the suggestion.
Change my cartridge same way but seems to run ok then once you turn cold and go back to hot it stays cold almost as if the springs locked and spring stick to cold??
Yes, sounds like something is sticking.......maybe best to take it back out and have a look at it to see if there is anything obvious ?
How do you know if you need a new cartridge, or just to clean up the outer casing of the valve? My temp valve has seized and only turns 1 way
Every situation is different, I could not comment without seeing that, but it is usually always good practice to change the valve.
Exactly the same shower I have, my shower is Luke warm even with the scalding stopper removed, is my cartridge goosed?
Hi, I am having an issue with my shower system, when showering with hot water, it then goes cold suddenly for a few seconds then it goes back to hot. Could this be a cartridge replacement issue?
this is only happening to my bristan shower system, no other taps around the house has this issue
thanks
Yes, sounds like a thermostat cartridge issue, best to replace the cartridge.
How do I fix a dripping shower problem for this same Bristan shower? Will changing the same part fix it?
No, you will need to replace the actual cartridge, it is the one above the one that I replaced in this video. The video shows replacing the thermostatic cartridge which controls water temperature. You will need the other cartridge which turns the water on and off. I am not sure of the part number but if you google Bristan Prism 3/4 cartridge, that should show you where to get them. Fitting is pretty much the same as I have shown in this video. I hope this helps ? 👍
@@Bacrenfencing thank you for the speedy reply - much appreciated. The problem is which part do I buy. There are a few that came up after google search. Wonder if Di Vapor has it
@@indranil2u I think they are pretty standard, maybe best to phone a supplier and tell them that it is a Bristan Prism shower, they will know what the part number is. I think it may be Bristan 00622206
How do I stop the water coming out I started to unscrew it and water was coming out
Are you sure you turned the mains water off completely ? If it is just tricking out, it is probably just some water in the pipes that will drain, but if there is some pressure to the water, then it is likely that you have not fully isolated the mains water supply.
