Issue with no water coming through inlet valves

[J murton]

Hi all

I’ve had an issue with the amount of water coming through two side inlet valves.

There are 3 toilets in total. All are tank fed.
1 toilet bottom entry.
2 toilets are side entry.

The tank is above and comes down through the ceiling into the toilet through a 22mm pipe.

It then t’s into the bottom entry valve one side and then feeds the two side entry valves on the other side.

The bottom entry valve fills the cistern well.

The two side entry valves are literally trickling barely anything.

I have made sure they have the pressure reducer is out.

Still nothing.

I’ve also taken the nut off the side entry and had a bucket under it to ensure no blockage. It fills fine not the best pressure but pipe is not blocked.

Any advice would be helpful

Thanks

What sort of fillers are they? Any pics

Grit in the orifices inside the fill valves,
Fill valves have got high pressure orifices fitted,
And /or fill valve diaphragms are hardened.

So there is is a viva side entry and a fluid pro.

Checked all of the above. I can only think to run the toilets from the mains instead. Unless I’m missing something.

i find viva not very good on tank only really suited to mains

What would you recommend for low pressure

Fluidmasters but tbh can’t beat the old part 2 ball valve

Just strange how the bottom entry works well but the side entry are dribbling.
