Why do I get a bubble in the top of the flow meter? There can be a small residue of air in the top of the flow meter. The higher the filling flow rate, the less air there generally is. As long as it is above the reading scale, it does not affect the reading. Over time, the air dissolves back into the water and will naturally disappear, as it is absorbed into the water.
Can you clean the flow meter inside? Yes, you can remove the flow meter part and clean it while the system is under pressure simply by closing off the lockshield valve first.
How do I clean and flush out an underfloor heating system? Both new and replacement systems (a system where a new boiler is fitted is classed as a replacement system) are required by the Building Regulations
1 to be thoroughly cleaned and flushed and a water treatment inhibitor added to protect the system from further corrosion. This is also particularly important where an underfloor heating (UFH) system is added to an existing heating system, to prevent the new UFH system becoming contaminated by water in the older system which may be contaminated with corrosion sediment. For further details of how to do this consult the following guides and code of practice:
- Domestic Building Services Compliance Guide
- BS 7593 – Code of practice for treatment of water in domestic hot water central heating systems
- BSRIA Guide BG29/2012 - Pre-Commission Cleaning of Pipework Systems
- BSRIA Guide BG 4/2011 – Underfloor Heating and Cooling
You require a 24mm AF hex spanner for flow meters and drain/fill valves, and a 26mm AF hex spanner for automatic air vents.
Can you connect a copper pipe to any of Emmeti Manifolds? Yes but we only cater for 10mm and 15mm pipe
Can I use 00400004 Tecno-Varia Auto Air vent with potable water? No you can’t, it is not made of WRAS approved materials.
Why is the amount of water in the flow meter different on different occasions? The initial amount of air can vary depending on your fill flow rate. Then it will be affected by your pump pressure, the higher the pressure, the less air that will be visible (as air is compressed under pressure). Over time, the air dissolves back into the water and will naturally disappear, as it is absorbed into the water.
Does flow affect the amount of water in the flow meter? The initial amount of air can vary depending on your fill flow rate. Then it will be affected by your pump pressure, the higher the pressure, the less air that will be visible (as air is compressed under pressure). Typically, you can evidence this, between when the pump is running, and when the pump is off. Over time, the air dissolves back into the water and will naturally disappear, as it is absorbed into the water.
