Cartridge 3079R

3079R we do not stock infographic
- These parts are coming directly from the manufacturer of your tap.
- The 3079R Red Diverter Cartridge that we have currently in stock is stiffer but should loosen out with use.
- We would also recommend that you purchase the 3192R Brass Casing as some customers have reported that changing only the 3079R Diverter Cartridge was not enough to stop the leak. They also needed to replace this 3192R Brass Casing alongside replacing the 3079R.
- In some cases, even by doing this there was still a leak and this is due to the fact that the 3192R Brass Casing currently available might be slightly different from older models. It is possible that you might need to take the top part (with splines) of the 3192R that you purchase and re-use the base part of your own 3192R to get the best fit to stop any leaks.
Post 2009 (but please check your own tap):Here are the measurements of the Brass Diverter that we stock
- Splines 18 (2 of the 18 are slightly wider but 18 in total)
- 48mm Brass to Brass
- 29mm Diameter of thread

Shipping Information:
We ship from Ireland. DPD have notified us that they are experiencing shipping delays in GB due to Brexit (Customs). They currently advise us that these delays are temporary. However, as per the Large Popup notice on our website that is there until you Dismiss it, you should allow a minimum of 1-2 weeks delays for your order to be cleared by customs. This backlog is due to the volume of goods now going to /from GB that have to go through Customs from January 1, 2021 due to Brexit. It is outside of our control. (There will be no extra or hidden charges with your order).
We intend that Brexit will have no financial impact on our customers.
