      Thomas Kirkham

    • A perfect replacement for the cartridge valve in our nearly 18-year-old Grohe shower.
      Best price by a long way of all the suppliers who had this in stock and delivered within 2 days of ordering.
      Fantastic service by NSS from start to end

      Mark W

    • A branded quality product sat a competitive price.

      Robert Piper

    • Easy order and swift delivery from NSS. I had problems regulation the shower and bath temperature overtime and was advise by Grohe technician to replace the thermostat cartridge which is all good upon replacement. Regarding fitting, note there is not written instructions just a parts diagram for you to figure out. It assumes you are a trade person and fimiliar with part replacement. If you refer to installation manual there is a section on maintenance/replacement of the thermostat cartridge.( ps presumably you could download one from grohe website if you dont have one. Straight forward replacement.

    • As far as delivery, packing, price and ease of ordering .. 5 stars.
      Since the item it replaced lasted 10 years its a bit early to give it 5 stars for performance.

      Hugh Grant

    • Easy to fit and did the job

      Prem

    • Saved our bacon!! The Groer
      Shower thermostat had gone and thought little chance of a spare, but NSS came to the rescue. Part arrive very quickly and now we are back up and running at the right temperatures. Fantastic service and product. Many thanks. Paul

    Ask a Question

    • I have a grotherm 1000 34624. it has suddenly started only running cold and not at all if the hot is fully on. Would this be a problem with the thermostatic valve ( 47450 )?

      Hello, you need to check the inlets for blockage first, then if you do not find any blockage, you can replace the 47450, but no flow at all, would suggest a blocked inlet/non return valve.

    • is it possible that a new replacement cartridge is faulty, only we have had two new ones and it has not solved the problem. We have just
      had our boiler checked and every thing is running perfect, also cleaned filters and replaced valve in shower it is mixer shower over a bath we have very hot water in the bath tap, but only warmish water at the shower, we have tried every thing running out of ideas hope you can help.

      Hello, are you re-calibrating the temperature after fitting the new cartridge?, by adjusting the black hub?

    • Hi
      I have a megaflo system and sometimes my hot tap in the kitchen runs cold. I have checked everything possible, but, could it be a faulty thermostatic valve in my Grohe Automatic 2000 shower. Its about 15yrs old, and now just needs VERY small adjustments to change temperature.
      Many thanks
      James

      Hello, it sounds like you may be getting cross-flow through the shower, which means the non return valves are stuck open, they can be removed, cleaned and replaced,they are either side of the temp cartridge 47450.

    • My Grohe Automatic 2000 34310 doe not turn of the water without a lot of force on the knob. What might solve this please?
      Rgds Ray

      Hello if your on/off valve is screw-down, ie it turns more than 1/2 a turn, then you need part number 06905

    • The diverter in my up to now excellent Grohe bath shower mixer, which has a shower symbol on the top, is only diverting approximately 50% of the water to the shower. Is it something that can be fixed without buying a new shower mixer? Is the necessary part(s) still available? I can attach photos to identify model no. It is definitely Grohe, and approx 16 years old.

      Hello, please can you send a photo so we can be sure of getting the right parts first time.

      Hello, this cartridge is used in many other showers, we need to know which shower you have. Can you e-mail a photo to us salesdesk@showerspares.com

    • We have recently had fluctuating temperatures on two Grohe showers installed about 9/10 years ago. Plumber inspected them today and confirmed that we need new cartridges........... but we can't find the exact code numbers or details of the shower control units and I long ago mislaid the paperwork. Might you be able to identify if I sent photos?

      Hello, yes, please send us a photo of the trimset and if poss of the cartridge.

    • I have a Grohtherm 3000 about 10 years old now but recently it has been fluctuating water temperature whilst in the shower. I replaced the thermo cartridge but no improvement. I am still experiencing fluctuations in water temperature, not massive but enough to make it uncomfortable while in the shower. Can you suggest any other corrective action please or replacement of existing part ?

      Hello, is the shower on a combi boiler?, if it is it may be the boiler 'cycling' a blocked shower head can cause this or partially blocked inlet filters. we hope this helps

    • My Grohe 47450 came with a small sachet of what looks like silcon or grease. what is this for?

      Hello, please smear the grease on the O rings and any threads.

    • Our Grohetherm 3000 - 19663 recessed bathmixer will only produce luke warm water. The sink tap next to the bath has hot water. Is the thermostatic valve inside broken?

      Hello, yes the thermostatic cartridge will need to be replaced

    • Hi,
      We have a Grohe Sentosa oval shaped shower which is concealed behind the tiles so we can't get at the product code. Is the Grohe 47450 the right valve as the shower is permanently far too hot even when the dial is turned to the cold setting.

      Hello, if it is just a shower (not a bath/shower) then yes, the 47450 is the correct part

    • My Grohe Automatic 2000 Shower valve has become unstable controlling the temperature will 47450 fix it? The valve is more than 10 years old!

      Hello, if the shower is running very hot or stuck on just one temperature, then the 47450 will cure the fault, if however the shower is cycling hot-cold-hot, then you may have a problem with the hot water supply, is it on a combi? are the inlet filters blocked? is the shower head a bit blocked up?, both of these can cause a combi to cycle.

    • Hi, my Grohe Thermostatic shower valve has faulty temperature control, it will only run very hot, will the 47450 cure such a fault??

      Yes, the Grohe 47450 temperature cartridge will fix this fault
