With conventional, outdated U-traps, the risk of water leakage remains high, and even regular preventive maintenance cannot fully eliminate the problem.
When failures occur, the resulting collateral damage can be significant.

The conventional, outdated U-trap requires multiple PVC components, adhesive bonding, curing time, foam insulation, and sealing materials. Despite all this effort, it still fails to fully prevent pipe sweating or blockage. If aluminum insulation is used, the overall cost increases significantly without guaranteeing reliable performance.

Notice the difference: The same unit with the expensive aluminum foam insulation and after installing MValve.
MValve offers a far simpler, fully transparent solution that is quick to install and easy to monitor. Operation is straightforward, and cleaning can be performed instantly—on demand, whenever required.


PVC drain pipes are typically available only in solid colors—black, grey, or white—making it impossible for anyone to see inside.
Servicing is often incomplete, with residues left behind.
Over time, bacteria and fungus continue to accumulate in the U-trap, repeatedly forming sludge and causing recurring water leaks.
The world’s first truly effective solution to the persistent and frustrating water leakage issues caused by outdated, failure-prone U-traps.

MValve is a very simple full transparent pvc pipe containing a non-return air valve in its center. When the air condition is off, MValve is always empty and dry - contrary to the very old u-trap that should be always full of water to operate. Thererefore, no bacteria forming, no bad smell, no fungus. When the air condition is on, the condensation water will drain normally through the valve carrying with it, all dirt particles! MValve is the perfect solution to any Fan Coil Unit (FCU), virtually, maintenance free!
For ideal operation, place MValve at 1/3rd of the condensation drain pipe length.
Standard pvc connecters or removable type are needed. That's it!
With MValve, save 20 cm in false ceiling height and improve your Indoor Air Quality (IAQ).
Simply, cut and remove the exisiting u-trap. Deep clean the FCU (air filter, coil, drip tray, drain pipes) to be free from any dirt, fungus, gel or rust. Keep pouring water in the drip tray until the drain water becomes perfectly clear and transparent without any dirt particle. Then, install MValve on the drain pipe line as instructed, and enjoy a long and relaxing operation, maintenance free. That's it !
MValve does not have any mechanical part as hinges, screws or hard moving parts.
At its center, MValve has a built-in full transparent silicon membrane that operates as a gate and a door.
No rust, no freezing, no squeezing noises, no hang-up...
