How To Replace A Diverter Valve Cartridge And Head On A BAXI Duo Tec Combi 33HE Boiler

[@IanSlade1984]

I just followed along with this how to video on the same boiler used in the video and it worked perfectly. Hot water now restored, thanks for sharing.

[@kevinhancock4064]

Hi I'm pretty competent contemplating ordering the part got heating but hit water just going cold all the time think it's been long time coming ..just power off some draining and easy enough ? Currently got front off and lower section lowered

[@umarchetty1]

Dear sir...I have to say million thanks to you. You saved me so much money. I pray you always have Happiness as your your shadow.

[@fozaannaeem5362]

These vids are great lately. Hands on guide step by step. Doing my apprenticeship atm. And beginning to do more breakdowns, these vids are really helping me. 👍👍

[@PlumbingGy]

Brilliant thanks for the support👍🏻💪🏻

[@boogiemulee]

Thanks a lot mate. Fixed my heating for 20 quid. Legend 👏

[@craigjones6962]

Cheers fixed in 30mins saved me a few quid and no waiting for plumbers to not turn up👍

[@don4techy]

You saved me £750 mate. You're an angel. All working for 5 months now🙂

[@PlumbingGy]

Haha, glad to help. Smash that subscribe button 😉🤪

[@kevinhancock4064]

What issues were u having buddy?

[@northeastcorals]

Legend, just saved me a right headache

[@mrtickles2129]

Fantastic video, 30 minute job heating is back on for Christmas!

[@nareshsonithaleshwar3197]

Hi, Is there way to find out if motorised head is faulty or diverter valve cartridge is faulty?

[@ldosanjh2070]

Great video. The pin in my cartridge wouldn’t depress. It is stuck. It’s making a loud noise when switching over. Would this be the cartridge or the motor. TIA

[@bartooosh5099]

Hi, please help me 0:50 I can't close this valve, what should I do?

[@Chriswizzv12]

Hi there can this valve issue also cause the radiators to remain cold but have hot water? As I appear to have no radiator flow, but power to the pump and it sounds to be running. Thanks

[@oldguy8078]

I think so. Hot water but no heating. The diverter valve is stuck. This could be the issue.

[@chickendog27]

Big help, doing one tomorrow, huge thanks pal 👍

[@karldagnall8438]

Thank you for the tutorial video. I've just replaced a faulty diverter valve for the grand sum of £23.90. parts and a length of 10mm rubber tubing to connect to the drain off valve. Plumber wanted £180 all in

[@hippopotamus86]

I was just quoted £288.

[@Error_404_Not_Found_timed_out_]

Great video . . .but even though it seem a lot, that is standard price for a plumber

[@asicasualgaming5602]

I followed this steps and i fixed my boiler....thank you so much....

[@asicasualgaming5602]

I have a question....i just realised that after replacing that diverter valve ...when i use hot water my radiators start to heat up aswell even when the heating is turned off....any advice?thanks

[@PlumbingGy]

The role of the diverter as you know is to divert the water from the heating to hot water when required, I would suggest checking the diverter again for blockages/debris making it stick. Double check it is working and the motor head is doing its job too. 👍🏻

[@vcgohil2001]

very nice video .mine is jammed. cartridge is been stucked only top part of the cartridge comimg off rest has been stuck. do you any reason why is it happening. thanks

[@PlumbingGy]

They do require a slight wiggle but be careful not to snap it, as it is only plastic

[@adamek9750]

any clue what 5f means on the display? my central heating turns on randomly.

[@ph1009]

Thanks for the clear instructions on this video. I'm getting a lot of water leaking out from just where the motor head sits - would this be an indication to replace the diverter valve as you've shown, or some other problem? Potterton Promax boiler, about 10 years old.

[@kevinhancock4064]

I'm hoping to do ours in next day or 2 . But get a new mot8r head only around 10 quid . Likeky just seals gone bad and the motor will be affected corroded etc

[@christopherdevoe5746]

Would this part only make noise when calling for hot water? Our system has been making a whining noise when only the hot water is called and running and not the heat. Seems like the noise is coming from the head.

[@PlumbingGy]

You may notice a slight whine if it's clogged or potential debris causing an issue inside, or when you hear it working it may sound like a click which can be a sign of the head going. 👍🏻

[@JJ-bv7fc]

Hi mate I have the exact same boiler but have no central heating should I change the diverter valve cartridge or pump? Thanks

[@PlumbingGy]

As long as you have the required certificates to work on gas 👍🏻👍🏻

[@akabowath3251]

My valve came with silicone do I need to use it if so where? Also what size plumbing grips will I need?

[@PlumbingGy]

Yes, and big enough to remove 👌🏻

[@TheMilkshakeuk]

Hello Dan , thank you for the video . Wanted to ask if i am going to replace a double check vlv isolator do i need to drain the boiler ? Or can i switch off the boiler and turn off the pressure keys to change the old vlv ?

[@PlumbingGy]

If you’re replacing the built in full valve then you don’t need to drain off just isolate under boiler and change 😊

[@TheMilkshakeuk]

@@PlumbingGy Dan you’re a legend - subd

[@kevinscott1158]

Hi. Watched this vid re changing valve motor unit. My duo-tec 5yrs old is tripping our circuit breaker and I found a water leak, just a bit wet, around where this motor unit is fitted onto the water valve. Do you think internally the motor unit might be getting water damage causing the trip? The plastic casing and where elec connector is fitted all looks dry though so was looking for advice. Replacing the motor and valve looks really easy for me and would be a great fix if you think is cause. Appreciate any feedback

[@grimawormtongue2014]

Is it really important to undo the flow nut underneath? As opening these old joints usually results in leaks afterwards.

[@PlumbingGy]

Never had any issues in all honesty 👍🏻

[@miketakla8641]

Thanks a lot just did the repair tonight worked perfect thx buddy

[@AaronYeamate]

This video saved me circa £300! A doddle if you can follow instructions. Cheers Dan!

[@michaelmcnamara8839]

Would this valve cause a grunting noise whilst running the hot water?

[@PlumbingGy]

It may sound like it's whirring but do not confuse with the pump

[@FATHEROFTHREEKIDS]

This diverter has been replaced 4 maybe 5 times in 7 years on my baxi duotech 24 he, any idea why this fails so often, also recently noticed hot water temp gauge goes over 60 when its set to 50, it also exceeds 65 which is supposed to be the max, do you think there is a fault with something or is this just normal for baxis

[@rowgli]

Mine has also apparently failed twice in the five years we've lived here. We have noisy pipes and what sounds like a water hammer issue. I wonder if a water hammer arrestor would help.

[@colingraham9281]

Hi I have had this issue on 2 boilers and had numerous cartridge valves replaced on both. It was such a joke, in 2018 Baxi even changed the boiler for free, ensuring me this would solve it. The new boiler lasted 15 months before that as well failed. It’s a moving part but it’s been massively under engineered to save costs. What they have saved in component build costs, would now be well outweighed by the amount of breakdown warranty claims. My boiler is currently broken down, awaiting another engineer visit to repair the same fault again. I am now considering getting the boiler replaced with a different manufacturer as it’s proven over 2 boilers these Baxi / Potterton boilers are really unreliable due to this fault.

[@kevinhancock4064]

Great video. Is this likeky my issue .......h9t water often goes luke warm or cold . Pressure of hearing system is mostly stable but can drop by 0.5 if it kicks . Rads all hot . Bled etc no air in rads . Occasionally 1 tap on its own won't activate the boiler but 2 taos will.....But often same issue with water going warm ir cold . Thank you I've got the both parts on order you mentioned inc a thermister just in case. Thank you

[@0macky0]

Long shot but did you fix it

[@colinjaap3911]

Done this and still no hot water any suggestions

[@kevinhancock4064]

Great video. In others they use a grease /lube?

[@seemaab]

Amazing video! Quick question, do you have to drain the radiators and the water to perform this repair? Many Thanks

[@PlumbingGy]

No only isolate 👍🏻

[@berrypickers]

Just changed my divertor valve and now my temp is going through the roof. Lots of scary noise coming from boiler. So much so that I've got to switch it off. Any ideas?

[@PlumbingGy]

I would go through the checks for the thermostat, without looking all I would suggest to start with 👍🏻

[@berrypickers]

@@PlumbingGy Think it was an air lock. I bled the pump and all my radiators and its all working now. Cheers

[@datageek9132]

Do you have to put silicon grease on the cartridge?

[@PlumbingGy]

It’s a good idea to

[@hamzaparvais3948]

Thank you so much great help and confidence

[@ryancoleman7875]

Hello, I have the same boiler. I drained the system and fitted a new radiator, I filled everything back up. Now my problem is I get hot water but no central heating. I can hear it turn on, but no heating to the radiators. So will doing this fix the issue.

[@PlumbingGy]

It could be a few issues, unfortunately without looking I can’t give you a good answer

[@joejoejoejoejoejoej]

Great video So easy when you know x Is it easy to change the heat exchanger in this type of boiler ? I have the 24 HE model and I’m going to attempt it. The manual says you have to firstly remove the gas valve !!!!! Also….. what gauge (bore size) is the orange tube ? 1/4” ?

[@justsamuelhaze]

Gonna attempt this next week

[@raihankhan5638]

Good explanation very helpful

[@mikepeck9260]

any links to where to purchase that cartridge?

[@PlumbingGy]

You will need a GC number off your boiler not a link as I could be different model

[@denlongstaff5436]

Thanks for that... really useful. Can I ask.... Why is the replacement cartridge shorter than the one you take out? Seems to have a bit missing ?? Cheers

[@PlumbingGy]

No difference in part maybe slightly new design functions the same

[@pgalaxy]

really clear, thanks perhaps you could over some details a bit slower, what does it mean recommision the boiler, is it just a question of pushing button?

[@PlumbingGy]

Thank you, Recommissioned and test, so make sure all your work is correct and the boiler functions and performs as it should. I personally test everything from leaks to flue performance while I am there so I do not miss anything nasty that may be lurking 👍🏻

[@pgalaxy]

@@PlumbingGy i want to become a plumber now, please start an online training academy, I ll sign up

[@nadeemhashmi7169]

Why did you not grease the seals with silicon grease?

[@PlumbingGy]

Because you do not need to.

[@adriatikqypi9356]

Nicely explained 👌

[@anthonycox1340]

Fantastic vid i sorted out my boiler thankyou

[@kevindietrich3874]

Do you have that part number?

[@PlumbingGy]

Sorry no, the boiler gc will give you correct part

[@johnthegodfatherslack]

No hot water. Ill try this tomorrow. Clean part and refit see if that solves it. Great vid.

[@PlumbingGy]

Give it a try john hopefully will work 👍🏻

[@jameselms7342]

Thank you for sharing this info, it helped me, cheers

[@AJGMB93]

I'm new to the gas world one question why is it called a 3 way cartridge if it only does heating and hot water? May seem a silly question.

[@weitubefan]

one input + two output = three ways🙂

[@abualam4418]

Great video

[@GulmazHd]

Hi Dan. How come this part was changed? I have the same boiler. Some of my radiators are hot, some aren’t even warming up. I’ve checked for air and flushed the system.

[@PlumbingGy]

This was changed due to the valve not operating correctly so it would either be hot water or heating, the other wouldn’t work at all. It does sound like yours may have either blockages or debris build up with the rads/valves, if some are getting hot you know the valve is working…. Unless they’re piped off the hot water circuit 🧐

[@GulmazHd]

@@PlumbingGy I doubt they’re piped off. Everything was working fine. Been off all summer then came winter and some were hot and some weren’t. I’ve thrown some flush into two radiators. I’ll let it get round the system. Then flush it out and see how I get on.

[@michaelrose5040]

Doing my ACS exam soon hopefully... great video mate thanks

[@PlumbingGy]

Good luck mate 💪🏻👍🏻

[@justsamuelhaze]

Engineer wanted £170 for parts for this job, I got them for £20 for the pump and the cartridge

[@kevinhancock4064]

What was wrong with yours mate ?

[@Bobbybulsara179]

Supply and demand

[@hippopotamus86]

Question, is this a job someone is allowed to do themselves? Quoted £300 for diverter valve replacement by a highly recommended local company. I thought you should never touch the boiler yourself.

[@rowgli]

I think you're probably good so long as you just don't disturb the gas system... At all!

[@barrycollins3962]

Not fancy mentioning how to check if a bypass is fitted ..🤔🤔

[@PlumbingGy]

Why would I mention that

[@barrycollins3962]

@@PlumbingGy maybe cos if divertor has the built in bypass from it as some do then the cartridge can’t be replaced and it’s a full new valve.. 🤷‍♂️

[@PlumbingGy]

It would be different therefore a completely different video. If the person replacing the part cannot identify simple observations before they order the part then they shouldn’t be touching it. Again it would be a different part entirely.

[@mikesimmonds1916]

The only reason I've watched was because the professional didn't turn up. Step 1 in being a British tradesman.

[@PlumbingGy]

Definitely, I would try to check their ratings next time and try to get a reputable one booked in 👍🏻

[@uktoilets6394]

Forget that what I said I noticed on your about your a plumber I was really just didn’t want people getting in trouble and it looks like one of the connections have been leaking On That boiler

[@PlumbingGy]

Yes it has however this video is only to explain how to replace the diverter, the customer is aware. Thank you 👍🏻

[@davecavaghan7889]

Sorry, since when does a plastic cartridge come out in one piece,do an honest video of real diverter cartridge replacement instead of you tube video world

[@PlumbingGy]

Sorry, but from all the ones I have done only one has ever broken on me, it seems you may be too heavy handed and I would suggest a more careful approach. Thanks
