How to fix low water level in toilets

Shelle

We have three toilets that are very low, one "normal style" and two that are integrated.  I am not a DIY person at all, Dad was the one that always did these jobs when needed, however he has dementia and is unable to help.  I have looked at lots of youtube videos and posts on this forum, but they all seem to show a different layout to the one I have discovered in the "normal" toilet.  So its not as simple as just turning the thingy (I did say I am not a DIY person LOL).  I cant even work out how to remove the panels for the two intergrated toilets so I dont know what their layouts will be.  Any advice please or should I get a plumber in as neither Mam and I can figure out what to do?

If you mean the cistern doesn't fill enough, you need to turn the red screw (downwards pointing stick) on the right to raise the height of the float (the little black box). 

When the water reaches the float, the float pushes up the stick which pushes up the red lever on the top and stops the water from filling the cistern. So if you want more water in the cistern, the float needs to be positioned higher up the screw.

I assume the cistern is the top bit, if so it has plenty of water, its the bowl in the toilet itself that is very low.  I cant see any screw on the red pointing stick?

Pic(s) of level of water in bowl(s)/pans?  Although usually one can't do anything about that level - it is in the design of the toilet pan that sets it and it's just a water trap to prevent smells from the drains...

Do they go to the same (low) level immediately after a flush? Or does the level drop over time? Any drains smells in the rooms?

Very clean cistern by the way!  Must be a soft water area or almost new.

Thanks for the compliment re cleaniness although done nothing to achieve that   We are in a "moderate" area which much contribute as its about 15 years old.  After every flush it goes back to being very low.  They (all 3 toilets) were always a bit higher than that and causing problems in one in particular as we are needing to flush the loo several times to get rid of number twos.  I have attached a photo of the toilet bowl.  I dont know how to access the other two yet.

Looks an acceptable level to me.

There is little you can do practically to increase the water level in the pan.

The water level in the pan is determined by how high the wier is at the back of the toilet. This is part of the toilet design and there is nothing you can do to change this level (other than leaning the toilet forwards, but that could make sitting on it somewhat uncomfortable, and may make flushing even more difficult)!

It looks to me like the level in the cistern is very low.  Not enough water in it for a decent flush.

Are the other two ones that have the cisterns behind a false  wall, or in a unit attached to the wall?

If in a floor standing unit fixed to the wall,  is there a top to it that can be removed?

Pan water level is unlikely to affect flush away of no2 and paper...  More likely you do need a higher water level in cistern to do that.  But there's not that much more that yours will hold.

Other cause may be a partial blockage of the waste pipework(s) restricting the flow of stuff away from the pan so it doesn't flush as well as it could if completely clear.  Do all the toilets share a single waste pipe / manhole... can you lift the cover to see how stuff is flowing and if there's any backing up happening?

This might need a plumber if you have no 'handy' friends, family or neighbours to help and advise on site.  It's hard to remote diagnose this sort of issue.

Hard to say conclusively from a photo but that cistern only looks about 1/3 full to me.

Looks like some over enthusiastic water saving.

Try the instructions @vacheron gave. Most cisterns have a maximum fill mark on them. Don’t fill above that.
