Where will I find the filter - not obvious. I can make out the pressure vessel safety valves and stop cock in the vicinity of the cylinder. The sequence of connections on the incoming cold main are main tap, closely followed by a drain valve, then the pressure gauge ( that has a bulky unit on...

Thankyou everybody for the advice. What is a full-bore maintap and what will changing it achieve

Time to fill bucket at kichen tap is 8.5 litres in 1 minute

Many thanks BigBurner. I am unable to test flow rate as I am not at home till later this afternoon ie 3-45 pm. I presume you are also confirming that problem is not related to the pressure vessel?

What would be the outcome of a loss of pressure in a pressure vessel on an unvented cylinder. When taking a shower if a hot water tap is opened the hot water flow in the shower turns to a trickle. Cold water mains is 1.5 bar

Thanks again Onetap We do not have an immersion heater. If the expansion vessel has lost pressure could that be a problem. Some more information we do not have any problems with the showers. The showers are approx 4 ft higher than upstairs sink taps. Will take your advice on service

Thanks Onetap. The water heater temperature is set so we can comfortably shower ie only a little cold water is required and a basin of hot water is hot but not piping hot if that makes sense. I did reduce the temperature setting as advised on this site but that did not make any difference other...

This morning the spluttering from the downstairs tap was a lot worse. Initially iit cleared and then after the water flowed well for several seconds started spluttering again. So the problem appears to be getting worse. I presume it can't be an air lock as it is a pressurised system and any...

Simond - thx for response. The system is unvented. Heat setting is 155 deg f which provides comfortable hot water ie not scalding.

I have a STATE gas fired water storage heater - SR8 50 NADS. It has worked fine for 11 years. However 12 months ago when the hot water was used in an upstairs basin the tap would splutter for a little while. This now happens in several other taps. I have read several notes on similar heaters on...

Will not be able to get my hands on part no's till I get home this evening but it is of USA manufacture - the company is STATE

I have lived in present house for 11 years. The house is heated with a seperate gas fired central heating system to the hot water. A gas fired balanced flue storage water heater provides the hot water. This works really well with hot water always available no matter how many showers etc are in...

I have a seperate gas fired DHW heater from my central heating. It supplies 3 showers, 2 baths, 7 sinks and a washing machine. The temperature is set at low end of the heat scale. A pressure vessel is also included un the system. For a little while now I have been experiencing a spluttering...

Many thanks. Did not hot flush but will give it a try. Would it be OK to carry out the work in spring when the weather should be warmer.

Fernox F3 - System was filled and drained 3 times. Did not take any readings as suggested though. Now I have the bacterial growth - will it cause any problems like blockages etc ?

Last spring cleaned out my central heating system. After several flushes introduced Sentinel X100. A couple of weeks later I noticed a slimy substance which according to Sentinel was a Bacterial growth which can happen when adding X100 into a central heating system. They suggested to bail out...

After spending so much time on system cleaning and piping modifications I did some research on system balancing and after several weeks of trial and error ie tweaking lockshield valves - on some radiators an awful lot I have got a resolution to the problem. I never thought this was an issue as...

Would n't the easiest solution be to turn the boiler down to zero
