Heritage showe 4 knob solid brass Cica 1993

Hi and thanks for your enquiry with the shower doctor,

The shower you are referring to is the Gummers 1850 shower,

Your shower can be serviced and will almost definitely only need new seals fitting to the cartridge if you want to save yourself money. These type of brass cartridges will need served every now and then normally when they start playing up with any of the following symptoms.

If you are experiencing the following problems the seal kit will solve these issues and is the cheapest solution.

Dripping when switched off

Shower valve stiff to operate

Shower temperature fluctuating hot & cold

Water leaking through the front of the cartridge

So i would suggest either fitting another seal kit to the cartridge or replacing the actual cartridge internally.


This shower and the spares diagram can be found via this link provided - www.showerdoc.com/sirrus-1850-1850-dual-shower-valve-including-sirrus-stratus-1850-shower-spares

You can buy the cartridge SK1850-2 which is what is in your image or you can service the shower cartridge with a seal kit on the same page as part number SK1850-1

The seal kit is the cheapest way of repairing your shower and the cartridge / internals is the most expensive.

You will also find instructional videos on the seal kit page on how to service your shower or replace the cartridge.

A new replacement shower can also be found to the right of the spares diagram via the above link.



Kind Regards
