What to do if your water meter's seal is broken or missing

Why the seal is there in the first place

The seal is a small plastic or metal tag, usually on a wire loop, fitted by the water utility or its contractor after the meter is installed or last checked. Its purpose is simple: to show that nobody has opened the meter housing or disconnected it from the pipe since that date. It is proof of an unbroken chain, not a decorative fitting.

Billing in Tallinn's water network relies on trusting the reading on the meter. If a meter could be removed, reset, or bypassed without anyone knowing, that trust would break down, so the seal exists as a low-cost way to confirm the reading has not been interfered with. It is checked whenever a meter is replaced, calibrated, or inspected.

How the seal usually gets broken

Almost nobody breaks a seal on purpose. It happens during ordinary plumbing work: closing the stopcock to change a washer, swapping out a tap, fitting a new toilet, or replacing a section of pipe near the meter. The seal's wire runs close to the union nut, and loosening that nut to turn the meter or shut the valve is often enough to snap it.

It can also happen through age rather than anything anyone did. The plastic tag becomes brittle after some years and cracks on its own, or the wire corrodes and parts. In older buildings with meters that have not been touched in a while, this is at least as common as accidental damage during a repair.

Who to notify

Once you notice the seal is gone or broken, tell your apartment association (korteriühistu) or building manager first if the flat is part of one, since they usually coordinate with the water utility on behalf of the whole building. If you manage the connection yourself, contact the utility directly.

Do this before you do anything else to the meter or the pipework around it. A prompt report, made before any inspection happens on its own schedule, reads as ordinary housekeeping. Waiting until someone else spots it during a routine check tends to raise more questions, even though the outcome is usually the same.

What to have ready when you book a resealing

Resealing is typically done by the utility or an authorised contractor, and it helps to have a few things sorted before they arrive. Note the meter's serial number and current reading, and if you know roughly when and why the seal broke, mention it; it is a small detail that speeds up the visit.

If the seal broke during work you did yourself, such as changing a tap washer or fitting a new toilet, it is worth having that plumbing finished and the connections tightened properly before the resealing appointment, so the meter does not need touching again straight afterwards.

• Meter serial number and current reading
• Rough date and cause of the damage, if known
• Any related plumbing work finished beforehand
• Clear access to the meter, with the surrounding area cleared
• Apartment association or utility contact details to hand

How a licensed job avoids the problem

A plumber who works on meters and stopcocks regularly knows exactly where the seal wire sits and works around it, or removes it correctly and arranges resealing as part of the job rather than as an afterthought. That is the main practical difference between a professional visit and a DIY repair done with a spanner from the drawer under the sink.

Our plumbing work, from 45 € per hour, includes handling shut-off valves and meter connections without unnecessary risk to the seal, and toilet repair and fitting, from 60 € per job, is priced so you know the cost before work near the meter begins. If a seal does need replacing as part of a job, we flag it and arrange it rather than leaving you to notice later.

Does a broken seal lead to a fine

A broken or missing seal on its own is not treated as proof of tampering. What matters is whether the damage looks like ordinary wear or maintenance, and whether it was reported. Utilities distinguish between a seal that has clearly been cut or the meter housing forced, and one that has simply cracked or come loose over time.

The cases that lead to real trouble involve a meter that has been bypassed to avoid being billed, not a snapped seal reported the same week it was noticed. If you are ever unsure whether a change to your plumbing counts as something that needs sign-off, the apartment association or the utility can tell you directly rather than leaving you to guess.
