We service Lifeline, PD and RRS extinguishers. Just click on the one you want serviced. Add to Basket, Fill in your details, Pay and post to the address provided. Extinguisher service is while you wait (by appointment) if you can get to Essex or 2 day turn around once received by post.
Do not leave the lever down. Use an oversize box as if it gets dropped the handle will become damaged. I cannot get replacement RRS valves they do not supply parts.
