Säker Vatten and Plumbing Self-Inspection Explained

Säker Vatten (short for Säker Vatteninstallation, literally "safe water installation") is Sweden's industry standard for plumbing work that is built not to leak, and the certificate that proves each job followed it. A plumbing firm becomes an authorised Säker Vatten company, its fitters carry a personal trade licence, and at the end of an installation the fitter fills in a Säker Vatten certificate documenting how the pipework, joints and wet-room penetrations were done. Insurers treat that certificate as the difference between a paid water-damage claim and a disputed one, which is why the paperwork matters as much as the pipework. This article explains what the standard actually requires, why a leak-free installation is worth documenting even outside Sweden, and how to turn the certificate from a Friday-evening paper chore into a two-minute self-inspection you finish on site.

What Säker Vatten is, and what it maps to outside Sweden

Säker Vatten is a set of trade rules (branschregler) owned and maintained by the Swedish plumbing industry, not a government law. It exists for one blunt reason: water damage is one of the most common and most expensive building insurance claims in the country, and most of it comes from installations, not burst mains. So the industry wrote rules that remove the usual failure points, and tied them to three things: an authorised company, a licensed fitter, and a signed certificate per job.

If you are reading this from the UK, Ireland, New Zealand or Australia, there is no identical scheme, but the shape is familiar. In the UK, WaterSafe and the water fittings regulations (WRAS) cover who may work on the supply and how fittings must perform. In New Zealand, a licensed plumber issues a certificate of work and, for larger jobs, a producer statement. Australia runs certificates of compliance per state. What Säker Vatten bundles into one habit is a leak-prevention rulebook plus a per-job record that an insurer will actually read. If your market has any compliance certificate for plumbing, the workflow below transfers directly: swap the rulebook, keep the discipline of documenting the job before you leave.

The three pillars: authorised firm, licensed fitter, signed certificate

The scheme only works because all three are personal and verifiable.

• Authorised company. The firm registers, agrees to work to the rules, and appoints a responsible person. Authorisation is checkable in a public register, so a homeowner or a housing association can confirm you before they hire.
• Licensed fitter. The individual plumber holds a personal trade licence earned by training and a test, renewed on a cycle. The licence belongs to the person, not the firm, so it moves when they do, and its renewal date is a scheduling constraint you have to track.
• The certificate. One per installation, filled in by the fitter who did the work, describing what was installed and confirming it follows the rules. This is the document the customer keeps and the insurer asks for after a leak.

Miss any one and the value collapses. An unlicensed fitter in an authorised firm still voids the point of the certificate. A perfect installation with no certificate is, to a loss adjuster, indistinguishable from a bad one.

What the Säker Vatten rules actually require on site

The rulebook is detailed, but the recurring themes are the failure modes that cause claims. Know these cold and the certificate writes itself.

• Everything leaking must be visible or drainable. Concealed joints behind a tiled wall are the enemy. Connections belong where a leak shows itself and drains to somewhere safe, not into a floor void.
• Waterproof layer penetrations are controlled. Where a pipe passes through a wet-room membrane, the detail follows an approved method so the membrane is not the weak point.
• Fittings and materials are type-approved and used the way the manufacturer specifies, with the right tools and joints for the pipe system. No mixing incompatible systems.
• Dishwashers and washing machines sit on a waterproof tray or floor with a drain, and shut-off valves are reachable.
• Water meters, manifolds and shut-offs are placed so a future fault can be isolated without tearing out the room.
• A pressure test confirms the system holds before it is closed up. You record it, because a test you did not write down did not happen as far as a claim is concerned.

None of this is exotic. It is the difference between a plumber who assumes it will be fine and one who builds so the one joint that fails in ten years fails where someone notices before the floor rots.

Why the certificate is worth more than the extra ten minutes

The certificate is a self-inspection: the person who did the work certifies the work. Sceptics call that marking your own homework, and on paper they have a point. In practice it does three jobs at once.

1. It protects the customer's claim. After a leak, an insurer asks whether the installation followed the trade rules. A completed certificate is the fastest route to "yes, pay it." Its absence invites a fight the homeowner did not sign up for.
2. It protects you. If a claim does land on your work, the certificate is your record of what you installed, tested and handed over. It moves the conversation from memory and blame to a dated document.
3. It sells the next job. "You get a Säker Vatten certificate" is a concrete promise a nervous homeowner understands, especially in a bathroom renovation where the fear is a hidden leak two winters from now.

The catch is that a certificate is only worth anything if it is actually completed, accurately, for every job. That is exactly the step that dies on a busy Friday, which is why how you capture it matters as much as the rules themselves.

Killing the paper without cutting corners

The traditional certificate is a paper pad in the van: fill it in by hand, hope it is legible, photograph it, lose the photo, retype it later. Every step is a chance for the record to go missing or go vague. The fix is not to skip the self-inspection. It is to make the digital version faster than the paper one so it gets done on the day, in the wet room, while the detail is in front of you.

A digital self-inspection should let you do all of this before you leave site:

• Open the job on your phone and start the certificate as a form built once from the Säker Vatten checklist, so nobody is retyping headings.
• Attach photos of the pipe runs, the membrane penetrations and the pressure gauge straight onto the record, geotagged and timed.
• Record the pressure test result and the materials used as structured fields, not a scrawl.
• Work with no signal in a concrete bathroom and have it sync when you are back in range, not fail because there is no bar.
• Take the customer's signature on the handover on the same device, and send them the finished PDF before you drive off.

This is where a field system pays for itself. In OdinTask you build the certificate once as an egenkontroll form template, fill it offline in the wet room, attach the photos to the job, capture an e-signature on handover, and the customer has the PDF while you are still packing the van. The next fitter uses the same template, so the record is consistent whoever did the work, and it is filed against the job rather than lost in a camera roll.

A practical pre-handover checklist

Before you call a wet-room job done, run this. It is the certificate in the order you actually work.

• Every joint is accessible or drains to a visible point. No blind connections behind tile.
• Membrane penetrations follow an approved detail and are photographed before they are covered.
• Fittings match the pipe system and are made up with the correct tool and joint.
• Appliance connections sit over a drained, waterproof surface with reachable shut-offs.
• Shut-off valves and the manifold are placed for future isolation without demolition.
• The pressure test is done and the result is recorded, not remembered.
• The certificate is complete, signed, and sent to the customer as a PDF.
• A copy is filed against the job so you can find it in three years when the claim adjuster calls.

Get those eight done every time and the standard stops being paperwork. It becomes the reason your work does not come back, and the reason a homeowner picks you over the cheaper quote who cannot promise the same.
