Reducing pump and solenoid valve sounds

Thanks for your comments Donn. Indeed trivia, but lets dig in ; If we presume a 14L boiler contains 7L 114°C water and we add 0,06L 10°C, we will have a new temperature of 113,1°C. My 6,5L boiler 3,8L 114°C and added 0,06L 20°C will be 112,5°C. A less than one degree heat reduction for

Reducing pump and solenoid valve sounds

The sure are. But they are (in my machine anyway) both made by Sirai. Good to know that you too consider the pressurestat sound being lower than the one from the solenoid valve. So the pressurestat, to my knowledge, react on pressure changes only. The solenoid valve is only activated when the water ...

Reducing pump and solenoid valve sounds

I read the posts about Sirai pressure switch. It made me a little unsure of how to act regarding my choice of pressure switch. The thing is, I have already purchased a Sirai. I ordered a 20A Sirai a couple of weeks ago, however, I got home a 30A. The 30A version will, according to the posts you

Reducing pump and solenoid valve sounds

To insulate the case might be a good idea. Most likely I will have to isolate the boiler from heat leakage in some kind of manner. Not sure yet, but as my current safety valve is leaking and causing excessive steam and heat, and I'm worried that the wallpaper will roll off the walls. Remains to be s...

Reducing pump and solenoid valve sounds

Thanks séb for feedback. I like the machine a lot. Only thing bother me was the pump. Well besides the ugly plastic panels... The nme pump setup is very quiet. I have added a quickmill membrane and bolted it down to a massiv junk of metal. The click sound is from the autofill valve, for time beeing ...

Reducing pump and solenoid valve sounds

Hi there! I'm working on a sound reduction for my pavoni 1el. Just changed pump from the original Ulka ex5, to a mini Ulka nme 1c. Works great, just some minor tings to add to reduce tube vibration in the reservoir. But as the pump sound was reduced, a new sound became more obvious. A click from the...

New gaskets for commercial lever group

Relax, this is a ok product. A "no name" product will of course not have a EFAS-certification. Part of a deal with a "no name" product. But if the compound is the same as dow/molycote, and if it clearly states that the product is food graded, it will be more than good enough for a super thin layer o...

New gaskets for commercial lever group

I found a "no name" silicone grease on a low market hardware store named "Claes Ohlson": {link}. Might be nice to know for the rest of the Swedes on this forum. Not a "genuin" mark, but for me, being a "Smålänning", it's right up my alley... (ops, that didn't came out right, did it?!?)
