Noisy Pump Out, Pressure Cylinder In (Soon)
- Thread starter bolo 2
- Start date
Plumber calling tomorrow to discuss the pressure cylinder system installation. Could someone please supply a list of the possibil pros and cons please. The plumber has already mentioned the possibility of leake with such a system. A quick reply would be appreciated.
Assuming you mean an unvented hot water system:
1. Minimum cold water mains pressure of 2.0 bar. Dynamic = pressure at 1 mains outlet with another mains outlet running.
2. Minimum 20 litres per minute flow rate. Measured "open pipe", i.e. with no restrictions in place.
3. The installer MUST have a current "G3" accreditation.

Thank you for your quick ,reply. I am not going to pretend that I know what any of it means but I do know that I can use the information to my advantage starting with, “You do have a current G3 accreditation, don’t you, that’s a must as far as I’m concerned?”..

1. Pressure is what drives the water through the pipes. One bar is roughly equal to the pressure at the bottom of a column of water 10 metres high. If the pressure is inadequate, then the amount of water flowing will be insufficient.
2. Flow is usually measure in litres per minute (lpm). It is a function of the pressure of the water, moderated (reduced) by any restrictions on flow, such as narrow pipe, valves half closed, too many bends. A good shower generally requires a minimum flow of around 10 lpm. To allow for other appliances being used at the same time, a good margin is required, hence the suggested minimum flow into the house of 20 lpm.
