FAQ

The space with a recessed or open back is called a shaft. To make your sink cabinet moisture and water safe, place a new chipboard or plywood board on top of the cabinet bottom. Make sure the board covers the entire bottom as well as the shaft.

If there are pipes installed, cut U shaped openings in the board. You will find illustrations in the installation instructions for sink cabinet inserts.

The difference lies in the manufacturing method. Pro trays are molded, while Standard trays are stamped.

This means that Pro has a thicker bottom and is more durable than Standard. Pro drip trays are available for dishwashers and fridge freezers, while Standard trays are available for dishwashers, fridge freezers, wine coolers, cabinet inserts, floor protection and other water connected appliances. Both models are tested and type approved by RISE.

By using two cabinet inserts joined together. See examples at tollco.se

Yes, but the placement requires additional measures. The purpose of the exception that allows washing machines in kitchens is to meet accessibility requirements when the bathroom or shower room is too small.

A washing machine in a kitchen must be placed on a watertight tray with raised edges all around and be equipped with a leakage circuit breaker connected to a moisture sensor placed on the watertight tray, or be installed with a floor drain and a water alarm.

Boverket’s Building Regulations (BBR)

6:51 General
“Buildings must be designed so that moisture does not cause damage, bad odor or hygienic nuisances and microbial growth that can affect human health.”

6:5334 Concealed surfaces
If there is a risk of leaking water or condensation on concealed surfaces in a room, outlets from these surfaces must be arranged so that water quickly becomes visible.

We have a tray called K55 for fridge freezers.
Item number: 3003002-01-015

Our trays are made of environmentally friendly polypropylene.

PP has the advantage of being accepted by Byggvarubedömningen, Sunda Hus and Svanen.

The ribbed side should face down, into the bottom of the sink cabinet.

A water connected appliance must have a tray with raised edges all around and a leakage circuit breaker connected to a sensor placed under the appliance that shuts off the water to the appliance in the event of a leak.

In 2020 we launched a completely new series of appliance trays for fridges and freezers where the front edge also has a raised lip to prevent water from running directly onto the floor. This allows you to see the leak before any damage occurs and gives the leakage circuit breaker time to shut off the water if it is connected directly to the appliance.

A water connected appliance must have a tray with raised edges all around and a leakage circuit breaker connected to a sensor under the appliance that shuts off the water to the appliance in the event of a leak.

The raised edge on our standard appliance trays is 40 mm, which has been tested and approved by RISE.

The requirement for trays for appliances is that they must be function tested and approved.
For plastic flooring, the requirement is a 50 mm upturn in order to create a reliable welded joint in the corners.

What applies when installing a coffee machine or other water connected appliance?
In such an installation there must be a leakage circuit breaker with a water sensor under the appliance that shuts off the water if a leak occurs. There must also be a tray with raised edges around the appliance.

Our inserts and appliance trays are made of polypropylene plastic, and common sealants such as silicone or similar products do not adhere properly to this material.

We have therefore developed sealing kits where the seal consists of butyl rubber, which adheres to this plastic and is also a very flexible seal.

It should be installed so that water quickly becomes visible. For fridges, the tray should extend to about half the thickness of the door so that any water becomes visible when you open the door.

The connectors for the sensors must be fully pressed in. Often you think the connector is fully in place, but it may need to be pushed a little further. Also check that the fabric covered sensors are dry. If it is a short beep, it is time to replace the battery.

Yes. The villa system can be controlled using an adapter and a smart plug from your alarm provider. With this solution you can turn the water on and off via your alarm provider’s app.

The red water sensor can be cut to the desired length with ordinary scissors. If you have a cotton based water sensor, it cannot be cut.

The red water sensor can be shortened with standard scissors, but a cotton water sensor must not be cut.

Yes, absolutely. You can buy a splitter from us that lets you connect both plugs. Alternatively, you can connect one sensor to the terminal block on the circuit board (K81, prb prb) and the other to the connector on the underside of the control unit.

See manuals in the Document Library. Document Library.

No, unfortunately not. The control unit does not have a radio receiver and therefore cannot communicate with wireless devices.

Yes. We sell an extension cable as an accessory, it is 5 meters long.

We have leakage circuit breakers, water fault circuit breakers and water shutoff devices. They differ somewhat in function and area of use.

Water fault circuit breakers use measurement and or sensors to monitor the entire potable water system, detect leaks and shut off the water centrally at the main inlet.

Leakage circuit breakers use measurement and or sensors to monitor locally, detect leaks and shut off the water locally or centrally.

Water shutoff devices use remote control to shut off the water centrally or locally, for example via a presence detector for lighting or a timer.

As a private customer, you can buy our products in well stocked building supply stores such as K Rauta, Beijer, XL BYGG and others. As an installer or contractor, you will find our products at HVAC wholesalers such as Ahlsell, Gelia, Dahl, LundaGrossisten and others.

Tollco systems are designed primarily to protect moisture sensitive building materials from contact with water or moisture, as well as to shut off water flow with water fault circuit breakers and to provide alarms if a leak occurs.

Please note: If you use other similar products from competing companies together with Tollco systems, we cannot guarantee the function of the system. We therefore recommend using only our products within the system, as they are tested and type approved by RISE.

See also: the industry regulations “Säker Vatteninstallation” (Safe Water Installation), a set of rules developed by the industry to reduce the risk of water damage, spread of legionella, scalding and poisoning. The regulations place requirements on both installers and products. The aim is to provide increased safety and security for users.

All installation work is carried out according to the Säker Vatteninstallation regulations, which are now required by insurance companies, municipalities and major clients.

You can find a consolidated version of the Swedish National Board of Housing, Building and Planning’s Building Regulations (BBR) online. When you are renovating a kitchen, chapter 6 is particularly relevant as it covers hygiene, health and environment. Here you will find sections on water connections on concealed surfaces, microbial growth and more.

Type approval proves that a product has been tested and approved according to the rules and requirements applicable to that product type. The tests are carried out by an independent company, in our case RISE and SINTEF, which test and verify our products.

Type approval is a national system for assessing and verifying that building products meet the requirements in Swedish building regulations. Type approval may only be issued if the product is not covered by a harmonized standard or a European Technical Assessment (ETA) issued for the product. In Sweden, type approval is not mandatory for building products.

Type approved building products have assessed properties in the areas specified in the type approval.

The product is assessed only in those respects that are explicitly stated in the type approval through references to sections in BBR or paragraphs in EKS. Users must pay attention to this and read the scope of the type approval carefully.

The RSK database is a complete information source for HVAC products.

Here you can easily find information about HVAC products such as installation instructions, product sheets, type approvals and images.

An RSK number is a manufacturer and supplier independent article number for HVAC products in Sweden. The designation “RSK” originally stood for “Rörbranschens Standard Katalog” (the pipe industry standard catalogue) but is no longer spelled out. An RSK number is intended to be permanent, meaning that discontinued articles can still be found for spare parts and replacements.

There are several reasons to water proof your home, not least to avoid the inconvenience and costs associated with water damage.

Insurance companies also reward customers who have water proofed their homes, and in renovation or new builds it is a regulatory requirement from Boverket that the property must be protected against water damage.
