Yeah, I think you've got things the wrong way around. If you do a search on google books, for NVQ plumbing you can get a preview of a really useful book. It tell you that you need the vent first, followed by the feed (both within 150mm of each other), and the pump should be ideally facing...

The vent pipe and expansion tank feeder are located before the pump, and the pump is the right way round. Systems was flushed in the last year and plenty of inhibitor added. If you drain a low point in the system you get a little sediment, but soon clears. So it appears from previous replies...

Hi, I have a grundfos super selectric 15-60. If I have it on speed 2 everything works fine, but I get water trickling back into the feeder tank via the vent pipe. If I have the pump on speed 1 the boiler temp trips out on CH and HW. I have been into the loft, and the height of the vent pipe...

Hi, I recently changed a radiator, so as the system was partially drained I topped up with inhibitor. Before adding Sentinel X100 & X200 I noticed that the header tank had dark 'gunge' (apologies no better word to describe it) around the waterline and in the bottom. I was surprised as I only...

Hi, recently changed valve & head (head burnt out). Wired up as instructed, completed all checks and confirm working as expected. I have noticed that a 'feature' that is probably there all the time, but only apparent when you start looking. If you have HW Tank stat satisfied, the controller...

I'm sure the dampness is due to cold water pipes, and cold walls in a warm damp room. Try to increase the air circulation before attempting anything like rendering

Contact your council. I'm sure environmental health will be able to assist with it ?

My house was built in 1989. Downstairs we have a 1" blue board fix to the internal wall within the cavity. For some reason, I assume cost,they didn't bother to put it upstairs. This is really frustrating because two bedrooms with North facing walls are really cold, and you are not allowed to...

I've just descaled my boiler. Symptoms very similar to yours. I used Fernox DS-40, but isolated all the radiators to minimise leak risk. Ran the Ds-40 for 24 hrs (using plenty of hot water to keep tghe system in use) Once neutralised, and fully flushed, I added Sentinal X-100 and X-200 which...

Hi can you help? I have recently successfully de-scaled my boiler with DS-40 (added to H/W side only for 24hrs, then neutralised). As part of that process I drained the whole system and added inhibitor (Sentnel X-100 plus X-200). Unfortunately I now have some form of debris rattling in a...
