Rated 5 out of 5 by Easy to install... After my old valve had ceased due to limescale, time for a new one. Really easy to fit, 10 minutes max (there's loads of tips on YouTube if you're not sure what to do). Being all brass, it should be durable too, although too soon to confirm 5 stars, good value for money, I was expecting to pay more... 22 Jul 2016
Rated 5 out of 5 by Built to last Good value valve, I prefer to spend a little extra for a Pegler valve, direct replacement for most fill valves out there.. 14 Jul 2016
Rated 5 out of 5 by Easy to fit and good quality Easy fit to replace decades old original. Mostly brass construction. Let's wait and see on performance and reliability. 17 Jun 2016
Rated 5 out of 5 by Upgrade float valve Bought to replace existing Part 1 valve with leaking copper ball float. Easy to fit and set up, works perfectly (I have monitored for a couple of days). Only time will tell on long time reliability so have given four for that section. Friendly and efficient staff at Norwich Hall Road pick up point as usual. 1 Jun 2016

Answer: 
Hi

There is no minimum pressure specification for this valve, only a maximum of 14bar. The published flow rates start at 0.5psi which is classified as low pressure.

Thanks for contacting the Technical Help service

Hole Size

Hi

It's probably obvious on the listing (but I can't see it). Could you please let me know what size hole I'd need to cut in the tank to fit this?

thanks

Brett

Answer: 
Hi Brett,

The inlet tail thread is 1/2" BSP which has a diameter of 0.825" or 20.9mm therefore 22mm or 22.5mm should clear the tail.

Thanks for contating the Technical Help line.

Flow rate?

I have not long had a power shower fitted, & have just found out that the header tank can't keep up if two people have a shower one after the after. I've noticed the float valve in the header tank pretty much looks like one you would get in a toilet & fills up at the same sort of rate too. So my question is this, does this valve have a faster flow rate & fill up my header tank quicker? Many thanks

Answer: 
These valves have been around for many years in much the same format, so I suspect it is very similar to the one you already have fitted. The reason they are fairly slow is that you really don't want too much of a flow going in to the tank or it deprives the rest of the house.
There are two possibilities I would look in to. Firstly, fit a 3/4" or 22mm float valve. This may seem silly when its fed with a 15mm pipe, but really it will increase the flow. Secondly, you could fit a pump in the house to increase the cold water pressure. Increasing the pressure will increase the flow to all areas of the house, so will not result in you depriving the rest of the house.

Answer: 
It's a 1/2" fitting, so you need a 1/2" tap connector. These are available at Screwfix. To connect a 15m on the other end, you need something like a 1/2" tap connector with 15mm end feed. If you just search for that you will find it.

Answer: 
Hi Adiadi, thanks for contacting our Technical Support. The entry end of the valve is designed for connecting to standard 15mm copper pipe,so yes the tap connector is compatible.

Regards,
