Comments: What a fun site! I came across it accidentally while the British Gas engineer was replacing the Diverter Valve on my old Worcester boiler. Googling Worcester Bosch Diverter Valve brings up your article on the same subject, and I whiled away the hours reading about your positive experience and the horror story of BD, the contributor who didn't have such an easy time of it! The Homecare engineer just finished the job and my hot water works again, but it was touch and go. The PRV and the fan also had to be replaced, and what with getting the spare parts and fiddling with the flue, the job took the best part of two days. It's not a DIY job in my opinion, but then I try not to dabble in plumbing too much. In the meantime, thank you for the hours of amusement which your site provided, and please send my best regards to your charming cats.
Comments: Mathew I have just completed a diaphragm replacement on my Worcester CD24i boiler. After reading a lot about the problems, I decided to not remove the diverter but just remove the 8 bolts holding the diaphragm housing in place. It took me 2 hrs to remove the two cross head screws from the rear of the diverter, using many different versions of screw driver. I decided to replace them with 5mm M5 stainless steel Allen Cap screws which use a 4mm Allen key (M5 12mm 10 for £1.30 post free) from boltbase on EBay. Replacing the diaphragm housing using these screws was far easier. I needed to cut 3/16” off the top of the bracket which bolts to the housing to clear the head of the new bolt, (a five minute job.) I could see the cold water filter with the housing off which looked clear so it did not need cleaning as this can only be done with the diverter removed completely. Thanks a lot Robert
Comments: Thanks very much for the info and pics along with your detailed instructs/experience..
Although I did this job before, many laps of the Sun ago I did "NOT KNOW" that you could get the diaphragm on its own and save a lot of ££ in the process
I remember it being an awkward job but ancient boiler is still working well (I`m guessing it aint all that efficient tho`) much happier about the repair cost this time.

Comments: I am about to undertake repairing my Worcester 28CDI in the next few days when I cam across your article.. The experiences shared are very clear clarified by the pictures.. I'm going to try the route of replacing the diaphragm in the diverter valve first. Then clean up the heat exchanger and see where this leads. Without your article I don't think I would be attempting such a job. Thank you - I'll repost when the job is complete. (May even include a few smileys - we'll see !!)
Comments: Hi, Thank you for your invaluable commentary on how to replace a 24CDI diverter diaphragm, the photo's were a great guideon "how to" all that is missing is the easiest method on how to put back those silly pins on the low pressure side of things. Patience ic required and lots of it. Once again a BIG THANK YOU.
