How to Familiarize Yourself with Australian Spa Parts

Proper care and maintenance are crucial to the longevity of your outdoor water entertainment feature, most especially if they happen to have Australian spa parts. All the different parts of a swim spa equipment, from the pump motor to the heater element, manifold assemblies, main control units, relays to pc boards, blowers and pressure switch — they should be well taken care of and must always in their tip-top form. If something is needing replacement, then make no haste in doing so. 

Even if your hot tub or outdoor swim spa is made from high-grade Australian spa parts, keep in mind that over time they will still go through the normal grind of wear and tear. They can be replaced with original items when needed, or in the absence of which another brand of products of comparable grade and quality can be used instead, as per your requirement.

But don’t be afraid of trying out compatible items. Most of the time, they also offer optimum performance as opposed to how their original counterparts would fare, but at a much lower cost. 

Now is the time to get to know your swim spa or hot tub a little deeper by knowing what is inside them. 

Heater Elements

Even if people would usually blame it on a worn spa heater element, it is not always the case. We don’t think we would qualify it as among the most common causes of spa heater issues. A sudden drastic spike in the voltage could be getting into this, but then again, it could be something else also.  


What are the spa relays? Relays are qualified electrical switches, whose main function is to relay power from one single component to another. As for the contactors, they are quite different from the relays. They are another kind of mechanical spa relays intended for a larger load such as the heater of your swim spa.

Spa Filters

Spa filters are not likely to last that long since they are not designed to last forever and this is due to their intended purpose and that it is to filter out debris, dust, and other foreign matter from getting into your swim spa equipment and its internal components.

This is the reason why you need to keep an eye on them and depending on the frequency of use of your swim spa or hot tub, replace their filters at least once every 12-24 months.  

Wet Ends

If you have a swim spa, the wet end is the extreme end part of its pump and that is in direct contact with water and gets wet, hence, the name. The other end can be found in the motor and you must keep it as dry as possible.

Pressure Switch

The majority of house calls for spa heater repair works are almost always due to a dirty filter. A dirty filter will not let enough water to flow through. The purpose of the pressure switch is to sense the amount of water flowing and keep the heater from turning on. 

If you are not likely going to clean your spa filter, then you probably have a faulty pressure switch instead. Therefore you need another one, so replace it. 


Spa o-rings inside the unions are among the most well known. Opening a union will flush out the o-ring to an unreachable point, under the swim spa itself. There are instances also that O-rings can be found in chlorinators and certain types of swim spa filters. They can also be used in a pump’s wet end.

The Australian spa parts we enlisted above may not be completely exhaustive, but the core message we have here remains the same. Each single one of them must be properly maintained and should be well taken care of. Neglecting this aspect runs the risk of unnecessary damage to your outdoor water entertainment feature.

How to Identify the Best Marine VHF Antenna to Use

For anglers, when it comes to finding the most invaluable VHF antenna they would probably see it as finding a great bite. Or surviving a skunk perhaps. But seriously speaking, this could save their lives or keep them from getting stranded or mishap. 

An expert would always encourage us to buy the best possible antenna that our money can afford. Prices for these pieces of equipment would be ranging from around $30 to more than $300 on recreational fishing vessels. 

What is a Marine VHF Antenna?

ICOM, one of the leading brands of marine VHF radios says they have sensitive receivers. They added also that if you will match it with just a meager $30 worth of antenna, you may not be able to optimize the range that ICOM can obtain for you.

VHF marine antennas can be classified into 3 groups. These correlate to good, better and best items. The categories would include Galaxy, Classic, and Phase III models. As for the key differences they have with each other, that part will boil down to what they have inside, whether a combination of coaxial cable, copper, and brass or all brass and copper. The brass and copper type is capable of producing the greatest efficiency. 

But before they decide to take that plunge into the antennas, anglers must understand what an antenna is all about. It is a machine. Most ordinary people see it as just a piece of wire. We qualify them as a physically resonant circuit, catered and designed for the frequencies we are aiming to utilize. They are photon generators because they have the power to convert the electrical signals and render them to become photons.  

Leading manufacturers say that as a general impression consumers think VHF type of antennas would only transmit signals right from its tip. However, this is not precisely correct. They assert that this type of antennas radiates their signal right from the base up.  

We can attribute this to the energy that is surrounding the antenna and since their signal tends to travel by line of sight, the manner in which you installed aboard a vessel is a major key factor here.

Even if you happen to have the best brand of an antenna, you can’t expect to receive optimum performance from them if you place them too close to another similar frequency antenna (it could be another VHF or an AIS type). The same level of underperformance can be expected if you will mount them too near to metal objects or if you mount them too low.  

If you are experiencing radio signal interruptions and think that your antenna could be causing the problem, the best course of action you can try in this kind of situation is to have someone help you test the signal strength from another boat. Have this friend you have started the test by being fairly close to your vessel and then gradually moving away until the radio signal starts to dissipate.  

When you decide to buy and acquire a new antenna, or you have finally decided to replace your old one, there is a big possibility that you are not going to come across a tech creep that is also plaguing some other electronics types. The working technology behind VHF antennas or any other type for that matter is more or less defined by physics — there nothing much about has changed over time. 

Materials though had undergone some changes, but the significant ones so far have something to do with a combination of things: multifunctional radios and antennas (VHF and AIS together, or WiFi and cellular). Everything has something to do with centralizing these products in a much smaller footprint.
