Faq - Frequent questions

If the valve drips or frequently discharges, the system probably lacks an expansion vessel or, if present, it has lost pressure. We always recommend installing an expansion vessel together with a safety relief valve, especially if there is a hot water or storage heater present which, as it heats the water, causes the pressure to rise and therefore frequently triggers the safety relief valve. Roughly speaking, the volume of the expansion vessel must be at least 10 % of the storage volume.
