Plumbing Issue

Hi all, have just moved into a new House ( well its 22 years old), and having issues with the loos and water pressure, the house is a semi detached in Gorey hill, co Wexford and I have established that the area has an issue with water pressure and I will most likely have to get a water pump if I ever want to get a decent shower ( next years project).

My big concern is all of the loos, there are three, the main bathrooms, an ensuite and one under the stairs. They are all are really noisy when the water is filling up the cistern after a flush, and can take about 10 minutes. Had a plumber out yesterday and , he tried to fix the main one however he reckons I will have to replace the entire cistern fitting if I want a silent flush, he did replace the entire cistern fitting in the ensuite and that is flushing perfectly now, however, two nights I noticed there was no water in the ensuite bowl or cistern , but it was full the next morning, last night it was empty but full again this morning, does anyone have any idea what might be causing this, would it be a water pressure issue? By sheer coincidence Uisce Éireann were conducting tests for leaks in my estate yesterday so had a chat with them as they were testing in front of my house, and they said no leaks showing up for the plumbing in my house

Do you have an attic storage tank ?
This could be emptying at times which would cause the problems you describe.

If the water pressure drops below a certain level the attic tank will not fill from the mains supply.

If this is the problem you might need a larger attic tank.

I suspect this is the culprit for all. Water pressure is needed to fill the this tank and at night it probably is better due to less usage around you. This also explains why the ensuite doesn't immediately fill and is grand by morning. If the downstairs loo is close to the kitchen you could get the plumber to attach it to the mains but this is what's known as a Tipperary job.
