I bought these to replace the original flow valves on my Trevi shower - these used a plastic housing and this had completely broken away on one valve.
These replacements fitted perfectly, are very easy to operate and should be far stronger.
Good product and service, would recommend without hesitation.
Fixed the problem right away, quick delivery and cheaper than others!
TOP product shower working like new will be useing N.S.S again
Just what I needed. Very easy to fit. One cartridge was all I needed to mend the shower flow valve, although there are two cartridges in the unit.
Allowed us to repair our thermostatic shower instead of replacing the whole item.
Parts came on time. Easily identifiable on web site.
Great service /product as ordered
Mr A Felton-Glenn
Exactly what I wanted, even though I was asking for the wrong pair of valves. The guy on the phone was brilliant making sure I recieved the correct valve's for my shower
Upgraded part to original. Fitted fine as per telephone conversation. Works well. Perfect
After fitting a pair of these new valves the shower is now working perfectly once again.
very prompt delivery, new original part as described
The product was easy to fit and had great assistance from Trevor at National Shower Spares. Thank you as the plumber told us that the shower needed to be replaced.
The help I received to troubleshoot was great, I changed both flow valves and our 25 year old shower is now as good as new. The NHS are great but NSS is awesome!
Items received quickly and now installed and working excellently.
I got the product I needed quickly, no fuss service excellent
Part arrived quickly and I was able to track it for delivery.
I bought 2 valves for Trevi Therm Mk2, one old one was easy to get out of the shower body, the other, I used a trick that I found on the internet, to melt the old plastic part that was jammed in the body using a soldering iron.
Both new parts have all brass body which should not give that problem again (this was first replacement in 16 year old shower!).

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