You need a new storage hot water system (HWS) and you call a plumber to quote service for you. When this happens, you must be aware of the terms and the scope of the work to make sure you are getting the correct and complete service according to your needs and know what you are paying for.
So when a plumber quotes you for a changeover or straight swap, do you know what it means? It means that your old storage HWS will be replaced with a brand-new unit of the type. A straight swap service should include the HWS, the temperature/pressure relief valve (TPRV) which is the hot valve that comes with the HWS. It should also come with a gas permit if you have a gas HWS and all HWS services should come with a plumbing permit.
Storage HWS service checklist
So what do you need in a straight swap storage HWS replacement? In addition to the ones mentioned above, we’ve provided a checklist to help you keep track.
- A new ECV – A hot water system doesn’t only come with a hot valve; make sure that the cold valve is included too.
- Duo valve – This controls the cold water flowing into the storage HWS and prevents hot water from flowing out of the storage HWS and into the cold water supply. Your old one may not turn off the water properly anymore.
- Gravel pits – Your relief valves can no longer simply drip on the ground and must terminate in a gravel pit.
- Insulation for pipework and valves – The pipe between your duo valve and HWS inlet and at least the first 500mm of your hot line must be insulated, as well as all relief valves and tempering valves.
- Tempering valve – If you are changing your HWS size, moving it to another location, changing the type, and/or want to add protection to prevent people from being scalded, a tempering valve must be installed, so that water is only delivered at 50 degrees.
- Copper pipe – This is required for relief lines to gravel pits, as well as installing a tempering valve or any modifications.
- Gas ball valve – This is a shut-off ball type valve and all gas HWS must have an isolation valve.
- Removal – A storage HWS can weigh more or less 75kg and so make sure this procedure is included in the service.
- Additional required licence – In addition to having the right permits and a plumbing licence, if you have an electric HWS, your plumber also needs a restricted electrical licence to connect and disconnect.
How to look for the right plumber
Any good plumber should be able to give you a firm quote over the phone, chat, or email when you describe the current situation of your existing HWS or show them a picture. No need for a call out.
Another thing to look out for when looking for the right plumber is the range of options they offer to suit different requirements and budgets. Finally, make sure that you talk to a plumbing company that is compliant with relevant standards and laws.
