Repair first

Four cheap parts that fail before the tank does

Nine times out of ten no hot water is a part, not the whole unit, and it is worth finding that out before anyone quotes you three and a half grand on a replacement. There are four things that kill hot water far more often than a dead tank does, and every one of them is a fraction of the cost of a new system.

The element is the first. On an electric storage unit a failed element means no heat at all while the tank sits there perfectly serviceable. Common, cheap and quick. The thermostat is the second, and water that is lukewarm, or scalding, or that runs out much faster than it used to usually points here rather than at the tank.

The third is the tempering valve. It is mandatory on bathroom outlets and it is a genuine consumable. When it fails you get cold water at the tap even though the tank is full of hot, and people replace entire systems over it. The fourth is the pressure relief valve, and if yours is dribbling constantly you are dumping hot water down the drain and paying for it.

We test before we quote. If the unit is genuinely finished we will tell you that, show you why, and give you the replacement number. If it is not, we will fix the part and you can keep your money.

There is one symptom worth acting on straight away rather than waiting. If you can see water pooling under the unit or rust staining down the side of the tank, the tank itself has gone and it will eventually let go all at once. Depending on where yours sits, that is anywhere between a wet patch on the lawn and a flooded hallway, so it is worth a phone call the day you notice it.

Local knowledge

The Mount Barker pattern

Mount Barker's estates went in fast, and in batches. Whole streets were fitted out by the same builder with the same builder grade electric storage units at the same time, which means they reach the end of their service life at the same time too. If yours is around fifteen years old and starting to struggle, there is a fair chance three of your neighbours are in the same position this winter.

That is useful to know, because it changes the advice. On a fifteen year old tank with a corroded connection, spending money on a repair is throwing good after bad. On an eight year old unit with a failed element it is absolutely the right call. The age of the unit, not the symptom, is usually what decides it.

Out on the rural blocks around Mount Barker it is a different story again. Tank water and hot water systems do not get along, and sediment carried into a heater will shorten its life and discolour your water. If your hot water has gone rusty looking, the answer might be filtration rather than a new heater.

If it does need replacing, the three realistic options are like for like electric, gas if you are already connected, or a heat pump. Heat pumps run at a fraction of the electricity of a resistive element and there are rebates available, but they cost more up front and are not right for every install position. Gas is cheap to run if the line is already there and pointless to install if it is not. We will give you the running cost and install cost difference in plain numbers and let you decide, because we do not have a brand we are trying to move.

Frequently asked questions

Can you come today?

Often, yes. We are local to Mount Barker and we treat a house with no hot water as urgent, particularly with kids in it. Call 0410 063 121.

Is it worth repairing an old hot water system?

Under about ten years old, usually yes. Between ten and fifteen it depends what has failed. Past fifteen you are generally better off replacing, and we will say so rather than sell you a repair.

How long should a hot water system last?

Ten to fifteen years for a typical electric storage unit, longer with a stainless tank, and less on hard or tank water without treatment.

My hot water goes cold halfway through a shower. What is that?

Usually a thermostat, an element on a dual element unit, or a tank that is undersized for how the house is now being used. All of it is diagnosable in one visit.

Do you carry replacement units?

We can usually source and install a common size the same day, so you are not left without hot water overnight.

Can you install a heat pump and help with the rebate?

Yes. We install rebate eligible heat pump systems and will talk you through what you are actually eligible for before you commit.

Had Ash do two new/renovated bathrooms for us! From quote to completion, couldn’t say a bad word! Everything went exactly as he said on the day he said it would. He was very clean and respectable during the process and the workmanship was perfect. Couldn’t be happier!!

I had a shitty job no one else wanted to touch and got hold of this great mob of plumbers and in no time they were where I needed them and they completed the job very professionally and in a timeframe that I didn’t think possible. Amazing people, great work ethics and the price was fair and reasonable. I highly recommend them for any plumbing services that you require and I will use them again if the situation arises that needs good work done correctly and within a decent time frame. Thanks Assigned Plumbing Services. 😁
