Hi All,
Thanks in advance for any help. From reading posts, I see you guys like lots of detail. I apologise if this is too much
Problem in a nutshell, is that the shower has stopped giving cold water it seems. If you run the shower with the thermostat set to 'warm', then the water starts powerful, and slowly fades as the water heats up. Turning the thermostat all the way to cold makes it stop completely, turning it all the way to hot, it speeds up (But is VERY hot). Shower is fed by a Monsoon Twin 3.6bar pump by the hot water cylinder upstairs, shower is also upstairs. The pipes appear to go into the loft along, and down to the shower (rather than udner the floor). There are several stop cocks by the pump, and in the loft, and have tried to make sure they are all on.
This started occuring after a plumber visit to fix a broken heating pump. That was replaced, and central heating fixed, although I asked whilst he was here he could look at the cold water tank, as the feed constantly drips into the tank, and when we go on holiday for a week, it start going down the over flow to outside. The ball cock and mechanism were very scaled up, and looked ancient, so he replaced them. However, I started hearing a dripping a couple of days later, and noticed there was now a leak on the OUTSIDE of the tank in the cold feed, and water was dripping and making a mark on the ceiling. There was a stop cock a couple of feet from the cold feed, before the leak, so I turned this off, and called the plumber back, he make it a couple of days later. Whilst I was at work, my wife and a friend had a shower, and used up all the water in the tank and the shower stopped. After plumber had been, everything switched on again, tank filled up, but shower not giving cold.
So, my first thought is air in the cold watre pipe, but surely that doesnt make sense, as the twin pump is coming on when the hot is called for, so wouldnt that also pressurise the cold, and get the air pushed through easily? So i'm wondering if totally by coincidence the shower thermostat mechanism thingy (technical term) now has a fault, and isnt letting the cold come through?
The cold water tank has a vent pipe over it, as does a smaller tank, which I assume is the heating header tank. I'm not masively familiar with these things. Our hot water is gravity, central heating is pumped. Not relevant i'm sure.
Is it possible to get an airlock, that cant get pushed through, even with a 3.6bar twin shower pump??? When it runs, doesnt it pump both sides, or are they actually separate.
Many thanks in advance for any help.
Kevin.
