hissing
The Madagascar hissing cockroach (Gromphadorhina portentosa), also known as the hissing cockroach or simply hisser, is one of the largest species of cockroach, reaching 5 to 7.5 centimetres (2 to 3 inches) at maturity. They are native to the island of Madagascar, which is off the African mainland, where they are commonly found in rotting logs. It is one of some 20 known species of large hissing roaches from Madagascar, many of which are kept as pets, and often confused with one another by pet dealers; in particular, G. portentosa is commonly confused with G. oblongonota and G. picea.Unlike most cockroaches, they are wingless. They are excellent climbers and can scale smooth glass. Males can be distinguished from females by their thicker, hairier antennae and the very pronounced "horns" on the pronotum. Females carry the ootheca internally, and release the young nymphs only after her offspring have emerged within her. As in some other wood-inhabiting roaches, the parents and offspring will commonly remain in close physical contact for extended periods of time. In captivity, these insects have been known to live up to 5 years. They feed primarily on vegetable material.
When we moved into our house in 2016, the electric water heater popped loudly when heating. After awhile, I researched and realized that it was likely due to limescale and/or other sediment buildup. I flushed it multiple times, but never got it to stop popping, so I eventually decided to replace...
I’ve just noticed my outside tap is making a sort of hissing sound and the pressure doesn’t seem as good as it was. It has much less power coming out of the hose pipe. A few months ago the return valve was fixed as it got stuck could it be related to this? I’m happy to try taking it apart to see...
I hope you can give me some advice.
The day after a pump replacement last week, on my Halstead ace, the boiler and pipes made a hissing noise when the hot water taps were used - a noise like when the pressure is too low- this continued when the taps were turned off and until the boiler stopped...
Hello everyone.
I live on the 20th floor of an apartment building. Whenever the neighbours on the other side of the wall wash their dishes/open their faucet I heard this loud, annoying, hissing water noise.
Any idea what's causing it to be so loud? Anything that can be done to fix it or, at...
Hi all. My house was built around 25 years ago, and I think the toilet might be that old. The toilet is making a hissing noise, but there is no water leak I can find and our water bill hasn't gone up. Now the toilet will randomly stop working for a few hours and then all the sudden the hissing...
Hi all,
This is in no way a blame thread for the recent work I have had done as the guys were top notch, just looking for a bit of advice on a few puzzling questions I have since.
I had a power flush done as two of my 12 radiators were not getting hot in anyway even though the flow pipes were...
Hi all,
I had a new Baxi Duo-tec installed a couple of months ago.
Over the last few weeks I've noticed and intermittent high pitched hissing noise when the pumps running.
If I turn off the CH and then watch the boiler, the CH light and burner light switches off but the the noise stays...
Hi Forum,
There is a Caleffi Inlet Control Valve (1 piece) connected to the hot water cyclinder and the cold feed, that is periodically (every 5 mins) hissing air, out of the grey catridge, when the hot water is heating.
- I've search around for an explanation without luck.
I don't...
Hi all,
I need some advice please. I heard a hissing sound as my toilet was refilling and it was taking much longer than usual. When I took the top off I could see that small 'jets' of water were squirting out of the fill valve.
The jets are coming out of the bit that attaches to the valve...
Hi,
The pipes in my bedroom have begun hissing and whistling in the middle of the night. It happens between around midnight and 6am, whether the heating is on or off.
I've uploaded a video here (it may be quiet on YT - it certainly ain't at 3 in the morning):

We have an issue with our combi boiler constantly losing pressure. The plumber has been round several times to do different things but nothing has worked. I think it's one of those ' you have to see it', so I'm...

Just switched the central heating on in my house and my boiler made a hissing noise for around 2-4 seconds, its a Remeha Avanta Plus and I've noticed in recent weeks that its not keeping its pressure, I can refill it fine but it will then drop back down, sometimes within hours. It's due a...
I have an unvented system in my home. The fitters that installed it recently came back to replace the expansion vessel as it kept hissing. They said it was a fault with the seal on the expansion vessel. Unfortunately, the new expansion vessel is still hissing.
It sound like boiled water...

Hi,
So one of my radiators doesn't get hot at the top. I tried bleeding it, but after the hissing stops, there is no water.
Could anyone tell me why this is? And what do I need to do to rectify this problem?
Thank you

The radiator in my bedroom makes a hissing sound if I turn the valve up above 3 and it's stopping me from sleeping. :angry_smile:
Note that...
