Ask a Question

Hello,
Following on from this question;
In the answer to the previous question you mention that you need to change the metal tag on the top depending on whether it's for the hot or the cold. What does this mean? I can't see a metal tag that is adjustable in any way, am I missing something?
there is a 'w'' circlip on front of the cartridge, remove it and lift off the steel tag washer, the tag rotates in a cut out on the front of the cartridge, you need to move the tag back a 1/4 of a turn, by doing this you reverse the action.
Just checking does the cartridge on the left do the Cold and the right do the Hot, and which way do they come out of the box, all set to hot or all cold?

hello, just behind the W clip is a steel tag washer, which travels in the cut out on the face of the brass valve. by moving this washer 90 degrees it reverses the action (open/close/open)
Please click on the photo on the item page on the website, the photo will enlarge so you can see the washer

My flow control initially turns water on to the shower then fails to respond to any further increase in flow despite rotating the control.
After about 20 seconds the flow reduces and can only be (temporarily) increased by turning the temperature control up.
The gears and spindle are not worn, so do I need to replace the Trevi 1/2 '' flow cartridges ?

Hello, if you remove the spindle and cogs, turn the valves carefully with a pair of pliers, do they work?, if they do, and the flow still dimisnishes, you may have a supply/blocked filters problem on the temp cartridge.

Hi,
When my Trevi boost shower is turned off, it still drips water from the shower head. Is is likely to be the flow cartridge that needs replacing or the booster cartridge? When working the power flow and water temperature is fine.
Thanks

Hello, definately the flow cartridges, there are tweo in each shower, A952501 , it may also be the gearbox A963067

Hello, does this Trevi spare part 952501 do both hot and cold flow?

Hello, there are two of these 952501 1/2" cartridges in your shower, 1 for hot, one for cold, they are linked together by a gearbox, the cartridges are reversible by adjusting the metal tag on the top.

We had a Trevi A3000 unit in one of our showers which start dripping all the time. Eventually it failed altogether and the water just kept flowing even after it was turned off. I replaced both of the flow cartridges with these spares and it's back to normal again. Very pleased with the product and excellent speedy delivery.

Both cartridges were stuck into the shower valve body with scale. On unscrewing the brass nut separated from the rest of the cartridge which was stuck in the valve. It needs to be carefully picked out with a small screw driver. This took some time. Replacing the cartridge was easy and cleaning the temperature control filters has returned the shower to "as new" operation.

Fault diagnosed correctly by one of your engineers over the telephone. Part did the job perfectly. The plumber was convinced that the fault lay elsewhere, but he was proved wrong. Thank you for saving me a small fortune.

Excellent prompt service. Would certainly use them again. Very favourable price.

Online order process was simple and part arrived quickly. Unfortunately the part received was incorrectly made with the wrong thread pitch and so couldn't be fitted. After contacting company by phone and email a 2nd replacement part was quickly dispatched and fitted OK.
Dealing with company and response to solve the problem was good. 4 stars due to the grief from the wife for the time the shower was out of action.

There's not much you can say about the product itself, other than it does what it's supposed to do (fits where it's meant to and turns the water on and off without seizing up or leaking - so far!) but I really must say that the ordering process was excellent. The diagram and photograph meant that I was confident that I was buying the right part, and the package arrived very promptly.

A great product - did "exactly what it said o the tin" - but of more importance at the time was the help given by the Shower Spares team in making sure I had the correct part.
Well done and thank you again .

Spares arrived in good time. There was a problem with the handing of the valves but a phone call to the help desk resolved it with a simple modification. No instructions included but saved by good old YouTube.

Did the job exactly as it should have done. National Shower Spares' customer services were excellent in sending me all the details I required, along with identifying the fault I had (shower dripped and unable to fully turn off). I recommend that these are followed to the letter. I also recommend that the cartridge is 'greased up' before fitting.
Now shower control like new again with just a quarter turn.
All these items were delivered very quickly too.

National Shower Spares (ShowerSpares.com) is an easy choice. The exact item was delivered quickly within a padded postage envelope. I bought valves for my own shower and was impressed enough to return and order again when my friends shower needed spares.
I don't know if Ideal Standard's Trevi 1/2" cartridge assembly suffer from a design flaw, but the shower was passing, and on removing the old valves, they came out in half. To remove the base of the cartridge was almost impossible, and they didn't come out intact. The spares ordered from National Shower Spares (ShowerSpares.com) are an exact replacement, and fit first time. I would suggest you coat the 'O' rings in silicone grease or similar.
Thank you.

Delivery was fast and efficient. The two cartridges were mismatched which puzzled me until a telephone call to Showerspares made me aware of how to alter one of the cartridges to match the correct configuration. Satisfied with the service and the help

Super fast delivery (they said 3 days, it arrived the next day) and exactly as ordered. The shower valve we ordered was around £5 cheaper with showerspares.com than anyone else on line.
