We lived in Castle Hill for many years, and it has always been challenging to find a good and reliable local plumber until we met Greg. Greg is knowledgeable and easy to deal with. More importantly, unlike other plumbers who try to rip you off or take advantage of the situation, Greg's prices are very competitive compared to similar work. Greg is our number 1 go-to man in the Hills District.

Greg came out to look at my stormwater drainage issues today, only an hour after I called, was very helpful, professional and genuinely interested in working with me to find a cost effective and effective solution to my issues. He advised a possible solution that would both solve my issue and save money. Thanks Greg, look forward to working with you in the next few weeks to solve my drainage issues.

I called GSM plumbing to discuss the stormwater drainage needs. Greg was quick to come over and explained the proposed plan in depth. He also went to the lengths of explaining how I should plan the different ongoing renovations to save time & money overall. I found him very honest and direct and will surely book him for any future plumbing work. Good bloke.

4 Steps to check your hot water system

There are 4 steps you can take to ensure your hot water heater is working properly. A licensed and insured plumber can also diagnose and fix the problem.

Is there is any water flow from taps?

If there is no hot water coming out of the taps, check to see if there is any cold water. If the cold water is working then check the isolation valve on your hot water heater. It is usually a red or yellow handle. If the valve is switched off, turn it back on. If you have an electric water system, check the fuse box to see if it is working.

If there is no hot or cold water from taps, check the main meter

If there is no hot or cold water from any of the taps, check the main meter to see if the valve is on. If there is only one tap with no water, then check if the isolation valve is switched on. If hot water is coming out of the taps but there is no hot water pressure, this could be due to sediment build-up in your hot water heater.

Are there any leaks from your hot water system?

If you notice water leaks coming from your hot water system - especially if there is excessive water, then you should get it checked by a professional. If there is water pooling at the bottom of the water tank, close the tap supplying water and have a plumber inspect it.

Check temperature settings if the water isn't hot enough

If the temperature of your hot water isn't hot enough, you may need to check the temperature settings on your hot water heater. After checking the temperature settings, adjust the thermostat on your electric hot water system and allow an hour to see if the water adjusts to a good temperature.
