The one fitting you cannot do without

A house can limp along with a dripping tap or a cold radiator. It cannot manage without a toilet.

So you learn its habits. Jiggle the handle. Hold the button for a count of five. Lift the lid and push the float down by hand. Guests have to be given instructions.

All the while, water is trickling down the back of the pan day and night. And a toilet that is only just working picks the worst morning of the year to stop altogether.

How you get a plumber to call

  1. Describe the trouble

    Type your name, a phone number and your part of Dumbarton. Then say what the water is doing, or what you want fitted. If it cannot wait, switch on the urgent option.

  2. A local plumber phones you

    A plumber who works around Dumbarton and the Vale rings at the time you chose. Expect a few quick questions: where the leak is, how old the tap is, if the water is off.

  3. Hear the price, then choose

    The plumber tells you what the job should cost and when it can be done. Say yes, say no, or go away and think about it. You pay nothing for asking.

What is going on inside the cistern

Lift the lid and there are only two working parts.

The fill valve lets water in after a flush and shuts when the cistern is full. Older ones have a brass arm with a ball on the end, which is why people still say ball valve. When it wears, the cistern keeps filling and the surplus runs away down the overflow.

The flush valve or siphon lets the water out into the pan. A lever-handle toilet usually has a siphon, with a thin plastic diaphragm that splits with age. A push-button toilet has a drop valve with a rubber seal at the bottom. When that seal perishes, water slips past it into the pan without a sound.

Match the symptom to the part

  • Water runs into the pan all the time. The flush valve seal has gone, or the fill valve is overfilling.
  • The cistern hisses and never quite stops. The fill valve is not shutting off.
  • You have to pump the handle. The siphon diaphragm has split.
  • The button sticks or does nothing. The cable or rod to the drop valve has failed.
  • Water on the floor behind the pan. The seal between cistern and pan, or the pan connector to the soil pipe.
  • The pan rocks when you sit down. The floor fixings have worked loose, which strains every joint.

Tell the plumber which of these you have and if the toilet has a lever or a button. Blocked, not broken? That is on our blocked drains and toilets page.

When a new toilet is the better buy

Most faults are repairs. A new toilet is the sensible choice when the pan or cistern is cracked, when the glaze has worn so it will not come clean, or when the cistern is an old pattern and no spare parts fit it.

MyJobQuote's guide says a simple replacement typically takes two to four hours. The standard choice is a close-coupled toilet, where the cistern sits on the back of the pan. Wall-hung pans and cisterns hidden behind a panel look neat but cost more to fit and are harder to get at later.

Measure before you buy. The distance from the wall to the centre of the soil pipe decides which pans will fit without the pipework being altered.

Adding a toilet in Scotland

Swapping an old toilet for a new one in the same spot is ordinary plumbing. Putting in a toilet where there was none, such as under the stairs or in a new en suite, is a different thing.

Scotland has its own building standards system, with building warrants in place of the building regulations approval used in England. The Scottish Government's technical handbook lists the work that needs no warrant. Like-for-like replacement of a sanitary fitting is on that list. Work to provide a new water closet is named as an exception for some types of building, flats among them, and any change to how waste water is discharged is an exception even in a house.

So ask before the work begins. West Dunbartonshire Council's building standards team, based here in Dumbarton, can tell you if your plan needs a warrant.

Common questions

How do I know if my toilet is leaking into the pan?

Dry the back of the pan with toilet paper, then leave a fresh sheet stuck there for twenty minutes without flushing. If it is wet when you come back, water is getting past the flush valve. A few drops of food colouring in the cistern show the same thing.

Why does my toilet fill so slowly?

The fill valve has a small filter that clogs with grit, or the isolating valve on the pipe to the cistern is only part open. A plumber can clean or replace the valve. Check the little screw-slot valve on the pipe first. The slot should be in line with the pipe.

Can parts still be found for an old toilet?

For most, yes. Fill valves and siphons come in standard sizes and fit many makes. Push-button valves are less standard, so a photo of the inside of the cistern helps the plumber bring the right one.

Do not wait for it to fail on a bad day

A cistern that runs on is wearing its valve out with every hour. A pan that rocks is working its joints loose, and the leak that follows is not clean water. Both are short jobs for a plumber now and bigger ones later.

Say what the toilet is doing, lever or button, and your part of Dumbarton. Nobody bills you for a question.
