Exactly what was required, no problem installing item
Very competitive pricing, fast delivery and a wide range of products. Most firms sell this product and exclude the thermostat then charge extra. Very impressed.
Very easy adjustment on water temperature which was no any on the old one.Well done
purchased and delivered well before expected delivery date, excellent customer service also when i phoned to ask a question, and now a really hot shower working again
Able to repair a shower rather than rip it uot and replace - good news considering no spare tiles.
Good service, correct part delivered arrived on time
The valve is good quality band fitted perfectly. All seals were provided.
Easy to fit even for an amature.
Technical advice was great and delivery was very rapid.
Delivery a day late probably caused by christmas post but cartridge fitted more easily than expected. Something to note however is that it is supplied fully open and with the hot on minimum... not a problem but would have been nice to know...
Only two days for the product to get to me. Also instructions on how and what to do in order to fit it, which was very usful. Much appreciated.
An excellent and well made replacement shower cartridge. No more stiff control. The technical help line was very good. It would have been better to indicate the grease needs to be smeared around the back plastic unit not around the brass area.
Item arrived in good time with instructions to fit, very pleased
Excellent service and the shower part fitted easily. Would recommend the company without hesitation.
This was dispatched and arrived very quickly. It's super quality and has greatly improved my showering experience. The only downside is that most of the rest of my shower has been discontinued, so this cartridge is pretty much the only bit that I can actually replace!
Excellent service and advice. Delivery spot on.
Prompt accurate advice given , prompt delivery of the product . Excellent service .

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
