Pressure temperature relief and cold water expansion valves

A cold water expansion valves or pressure relief valve is a safety valve on all storage hot water systems. They are designed to relieve excessive pressure caused by the heating of water inside the cylinder. They come in two main types, a pressure temperature relief valve (hot water relief valve) which is installed directly into the hot water system, and a cold water expansion valve (cold water relief valve) which is installed on the water inlet valve assembly or before the hot water system.

Cold water expansion valves are set at a lower pressure than pressure temperature relief valves, which may explain why a cold water expansion valve is ‘dripping’ more than the pressure temperature relief valve.

Should they leak?

Both cold water expansion valves and pressure temperature relief valves are designed to leak when the system is being heated, however when the tank is full of hot water and not being used, the valve will shut off and should not leak. If a constant leak is present, that indicates that the valve is malfunctioning and this could be due to something such as calcium being caught inside the pressure relief valve, or the pressure relief valve may be faulty and require replacement. It is not a safety concern if the valve is constantly leaking however it will dramatically increase your water and gas consumption.

SOAK PITS

Soak pits are an approved point of discharge for drain lines (pressure temperature relief valve or cold water expansion valve) and shall be located so that the release of steam or hot water is controlled and does not cause a nuisance, is readily noticeable and will not cause damage to buildings or injury to persons.

Hot Water Systems that were installed pre 2018 may not have soak pits installed, however, soak pits are now a requirement on all new hot water system installations in Perth.

Hear what our customers have to say:

Had No Probs Plumbing out to replace my toilet, Connor was such a good bloke and did an awesome job too. Would highly recommend to anyone who needs plumbing work done!

Reuben Simcock

The person that did the scheduling was very efficient and explained all the costs up front. The plumbers turned up on time and even sent a text when they were 20 minutes away. The work was done well and each step was explained to me. The guys were polite and cleaned up after themselves.

Grant Stephens

Cam was on time, very knowledgeable, explained everything and gave me multiple options. When finished he made sure everything was cleaned up as well! It is good to see customer service does still exist. I would not hesitate to recommend them and will use them for any future work that needs to be done. Thanks Cam for a job well done. 😀

Tamarra Kemsley

I recently required the services of No Probs Plumbing for my house of plumbing horrors, Declan was excellent to deal with and managed to locate the issue and repair it quickly considering the work that was required. Also setting up a tap to help isolate the outside from the inside in an effort to find leak number two. Not the first time I have used the company and deffo wont be the last - excellent service, efficient and great customer service from every single person I dealt with.

Jonti

Declan came today and fixed a shower head and 2 taps. He was friendly, professional and worked quickly. Did a great job. I first had Dylan do work for me in the earlier days if his business. Great team of guys he had and good to see his business growing. Definitely refer no probs to anybody.

CK Taranaki

The guys arrived early and got right to it. they sorted what was causing the problem and anything else and informed us as to what needed doing and all costs. They let us know the options and we agreed on it. Both got stuck straight in and before we knew it, the job was done and everything cleaned up. no mess left behind. very happy with the workmanship, time doing the job and both very friendly and professional. Hoping to never need them again but if we do, we will get them again no questions asked. JOB WELL DONE!. NO PROBS

Bige Jones

Cannot recommend No Probs Plumbing highly enough. They were so fast, professional, kind, and knowledgeable. I appreciated how fast they arrived, the time they took to try and repair the old system and patience with me to make a decision on the new system. The workmanship was exceptional and were excellent value for money. Thank you

Rebecca Gaby

No Probs and their complete home filtration system are brilliant. They really know their product and are realistic with what your family or home needs. Their work is extremely neat and tidy aka they take pride in their work. Since installation we have experienced softer, clearer skin and water that tastes as it should - clean!! Best decision we made was to have the filtration system installed.

Janelle Edmondson

Quick response when contacted online. This was my second time using them and I am very satisfied with their work. I had issues with my sewage drainage. Conor was punctual and professional. He explained the issue with my sewage pipes, quoted the total costs upfront. My experiences have been positive with No Probs Plumbing and will definitely using them for future jobs if required.

Stefanie Lau

Been using No Probs for about 3 years and for 4 large jobs. Excellent team, well priced but more importantly they are reliable, trustworthy and honest. A rare commodity nowadays. Keep up the good work team.

James Rowbottam

Outstanding service, very professional and responsive. We had Connor come out the same day as our hot water system burst. He stayed late and got the job done thoroughly. Would recommend this service to anyone.

Holly Miles

Declan did a very good job installing my new hot water system and fixing up the leak issues. Very professional and giving me some good advice. Thank you, Declan.

Swanny

Called for assistance and received great and quick response. Assessor on site 2 hours after reporting problem with toilet suite. New suite installed less than 24 hours later with minimal disruption to floor tiles.

Clive Nealon

Hi, I recently had one of your electricians come out to install a new set of filters for my under the sink reverse osmosis water unit as well as repair a bad leak coming from my solar hot water system up on the roof. The young man was very friendly and completed the work quicker than I has expected. I wish that I could remember his name as he was first rate. I have now used your company on several occasions and every time the men who have attended to do the work have all been of a high caliber and have done quality work and I couldn’t recommend your company highly enough. Kind regards Richard Byron

Richard Byron

I’ve used this company many times and they have always performed their duties to the highest standards. They’re polite, efficient , reliable and charge accordingly which is cheaper than many others. Will definitely continue to use them and highly recommend their services too.
