changing fill valve on concealed lower toilet pan

[cidfenmaria]

Hi
Please forgive if this question is too simple

After flushing the loo takes ages to refill water. It says online I should change the filled valve/shank valve. The upper cistern is exposed and sits on the toilet pan but the lower pan have both sides concealed and walls down either side hiding the pines below so I can't have wrench access anything behind.

Do I change the fill valve the same approach as the open pan type which have side entry? If I pull it out would it snap the pipe connection causing bigger problem?

Thanks again!

probably on a flexi

Depends on what fill valve you have, but only easy choices you have is to simply replace the washer inside the valve, perhaps also having to clean the nozzle part, if one exists. Or you might find it it a fill valve with a stem part which can be taken apart, but not all do.
Note, - some valves have built in filters which can get blocked, but some of these filters are in the base of valve and can't be got at from above.

Steves right, if its a close coupled with a closed back it will most probably have a flexi for the cold feed to it, so you have to pull the toilet away from the wall carefully as much as the flexi allows and then isolate it and disconnect the flexi so you can split the toilet from the cistern to change fill valve.

Alternativly it might be easier and cheaper to turn off your mains at stopcock or isolate the cold water down service if its tank fed and then disassemble fill valve from inside the cistern. You may find some grit in the fill valve slowing it down. Don't disassemble until you can flush the toilet without it filling up again.

Agree with the above but ...
Would only pull the pan forward just enough to get a torch light behind and take a look, you might even need a small mirror. Could be easy but then again could be a nightmare for you.

Thanks for the advices and experience from above from you guys are brilliant! It's a flexi pipe and I managed to replace the fill valve. Now it gets the water into the cistern quickly and smoothly.

However it comes with a little issue. the water in the toilet cistern leak into the toilet pan when I turn the basin sink tap in the same bathroom and it stops as soon as I turn the tap off!?
where do I look at now?
