Quick delivery, correct part. Thanks to the team for quoting me the correct part number. Good comms.
Worked fine. Didn't realize that the body O-rings were not included but the old ones were OK to use.
Jonathan R Thomas
Exactly as ordered on schedule what more can you ask for.
Good service received quite quickly part was perfect fit .
Can't fault the helpful and quick service that I received. The part in the end was not right for me (through no fault of the company) and the refund process was straightforward and quibble free. These guys know their showers!
Fantastic service, very quick on delivery.
When my shower went to cold only I thought it would be a job for a plumber I was wrong I bought this replacement mixer and with a bit of help from YouTube removed the old replaced it with the new and hey presto we had lift off it couldn't have been easier and couldn't be happier

I have just received 2 x SK1503-2LP cartridges which you sent out to my plumbers merchant, Ashwell's In Cheshunt. These are to repair 2 x Armitage Shanks Thermostatic 3 showers. Can you please tell me what the 'o' rings are for which are loose in the accessory pack. There is nothing in the instuctions only on how to adjust the temperature.
Hello, one of the o rings goes inside the main body, the other is for the headnut. setting the temp is done via a grubscrew down the centre spindle , anti clockwise hotter, clockwise cooler, I have also e-mailed the instructions to you.
Hi I have a TS 1503 the temperature control is fine but it will not turn off fully and there is often a drip, It will sometimes stop if fully turned home hard.
Can you please suggest a path to resolution?
Hello, you have two options, 1 buy and fit a seal pack, (cheap but fiddly) or fit a new cartridge, (dearer but quicker) the seal kit is part number SK1500-1, the cartridge SK1503-2LP
Hello, Can you please tell me what size socket one needs to fit the head nut? Also how deep must it be to not touch the top of the cartridge. I have a Bristan Java JTHBSMVOC and it seems very difficult to access the head nut in order to undo it.
Hello, the headnut is 29mm, the depth is 47mm
I have a sirrus opec ts1503 and I can only get hot or cold out of it there is no middle ground for warm? I've tried adjusting the thermostat temperature but that hasn't worked? Someone said its the cartridge, are the replacement cartridges sold here also able to adjust the thermostat temperature like the one that's on the shower now?
If you are in a hard water area you may have to de scale cartridge, if this doe's not work you will require a new cartridge.
I have had our Sirrus TS 1500 for about 15 years . The water on max temp is not that hot although the water generated by the boiler is. Should look at repalcing the cartridge. Will this resolve the problem do you think?
Also is the screw holding the cartridge in a left or right had thread?
Hello, the part to replace will be the SK1500-3 stat & piston, the thread for the head nut is a std anti-clockwise thread
