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?

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

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?

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.

I am looking for shower catridge Grohe 1/2" Thermostatic Shower Cartridge - 47450 000. I don't know the number of control catridge for controling water.Can you please find out the other catridge for me and let me know the price of complete set.

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

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

The product was excellent, installation was straightforward. The advice given by the customer service department was also excellent as well as being courteous. Wouldn't hesitate to obtain any other spares from them again.

Grohe are probably one of the finest producers of brassware. NSS can supply parts for all current and obsolete products.

Direct replacement. No problems with installation and working correctly. Only reason not giving 5 stars: no instructions on how to replace part which could have been an issue if my customer had purchased it themselves.

Easy to fit once discovered how to remove the necessary components, as diagrams in booklet supplied with the shower were somewhat misleading. Shower spares also assisted in ensuring I got the right replacement as again the booklet was misleading. Care needs to be taken with the helix on the end of the thermostat the edges are very sharp and can cut your fingers.

Arrived quickly and competitive price. However the instructions showed a different mixer using the same unit and I had to work out how to fit the unit. It is now in place and working correctly.

Identified the part required using the online facility and the very good exploded diagrams. It fitted and is now working well. I have a very happy customer as do National Shower Spares. I will come back to National Shower Spares again as and when the need arises!

The part arrived the next day which was impressive. Our plumber did ring the Grohe technical support people just to make sure he was fitting it correctly but we were pleased with the excellent service from National Shower spares. Will use them again. Many thanks.

This is a company that knows what it is doing which makes a change. All that one requires are the following,
is it in stock
when will it be delivered
information when it was sent
please keep me informed.
This company does this.
Its a simple idea

Installation instructions could be improved. Diagram showed different model and no explanation as to what to do with Silicon grease.

This was a replacement unit for the original unit purchased some 16 years ago. Could be fitted straight in, plus special synthetic grease was also supplied.
