North Leeds Plumbing & Heating – Home Improvement and DIY Advice

By the time you reach step four of installing your water underfloor heating system you are almost finished. You will now have the manifold fitted to the wall, the floor insulated, the pipe work snaking neatly across the floor and connected back to the manifold. The next step is checking out the system.

Step four is where you need to check your work. Before the floor is sealed away forever, you need to establish that it really is watertight and the pressure in the pipes is correct. To do this, connect a hosepipe to the system and fill it with water. As with the previous stages, in depth instructions are always available on the Internet and you are advised to follow them closely. If you employed a plumber to fit the pipe work these tests are something he should be doing before he leaves.

Once the system is filled with water you need to check for any sign of leakage. Be very thorough with your checks, because once the concrete screed has be laid it can be very costly to correct any problems. Note the pressure displayed on the gauge and if you are sure there are no leaks monitor it for 24hrs. There may be a slight dip, but if the pressure falls dramatically or plummets to zero, then you do have a leak and you must find and correct it before you go any further with the installation.
