    Indication of WC Cistern flush valve letting by.

    Prompted only by the horror of a trebled water bill, I tracked the source down to a Geberit dual flush valve silicon/rubber seal washer that had deteriorated and become covered with "warts". (Not an uncommon problem! ) Isolating the WC, noting the dropped cistern water level later, and washer...

    Polypipe 43mm o/d pipe compatibles.

    An existing bath waste run is made up of polypipe 43mm o/d 40mm i/d with solvent elbows I need to make up a replacement run of pipe with various solvent elbows to fit between an existing straight compression coupling on the 43mm o/d (40mm i/d) polypipe and a soil boss compression fitting that...

    Felt Lap Vents in Loft

    Is there any advantage to using these mouldings instead of just inserting something (wood strip, pipe insulation, plastic pipe, etc) to separate the felt layers? Do they increase risk of insect access?

    Frozen Pop-Up

    This is still not solved and I cannot get past the pop-up so can't continue into the forums. Others seem to be having problems also related to this pop-up.

    Frozen Pop-Up

    Recently a green bordered "Privacy & Transparency" pop-up has appeared on opening DIY not forum. It does not respond to clicking on "Continue with recomended cookies" and no further progress is possible. I am using an old (V9) ipad for this purpose that has been OK previously, and an alternative...

    Access to Paint fascia over porch

    This should be a simple paint job, but how would you reach the fascias over the porch roof? The slope is uncomfortable to stand on, ladders will not angle over it and the roof is slate which could be troublesome. Is it OK to just stand on it (Rafters cannot be located) or are there any useful...

    Fitting Hot Tank Thermostat

    Thanks, but that is not directly relevant to my problem and was never needed in the past. PS jeff's signature has nothing to do with this Tony !

    Fitting Hot Tank Thermostat

    Fully accept that, but in this case a minute change in the the dial setting results in a scalding or totally lukewarm tap output change, so the sensitivity range would have to be vast. (The stat marked temp is not what I am working on.). If I set the stat at about 55c the water remains cool but...

    Fitting Hot Tank Thermostat

    Thanks. I can see that, but I would not expect a stat sold for this purpose would have such a massive differntial nor for so many to display a fault.

    Fitting Hot Tank Thermostat

    Thanks for the interest. That's true and that was the original position of the stat. However the problem as described existed at that point and moving it higher was an attempt to check for and discount stratification, but neither changed the symptons. Therefore the problem is not arising from...

    Fitting Hot Tank Thermostat

    I am still struggling with this one and have no remaining ideas to resolve the situation. The DHW will only set to produce a tap exit temp that is far too hot or far too cool. I have moved the tank thermostat so that it sits at 1/4 down from the tank top,( to see if stratification and low use...

    DIY gas thread - I'm confused

    Exactly--so we are stuck with the Gas Regulations regarding a DIYer being competent. and whether there is any law placing an onus on them to demonstrate competency.

    DIY gas thread - I'm confused

    Health and safety at work act 1974-- does this apply to a DIYers own "castle?" Competence is a combination of practical skill, training, knowledge and experience to carry out the job in hand safely, and ensuring the installation is left in a safe condition for use. Knowledge must be kept up to...

    DIY gas thread - I'm confused

    "if you can't prove competence, you are breaking the law by doing DIY gas work." This is the failing in all the debate.---No such law exists. The law states simply that no person shall undertake gas work unless they are competent, yet the term competent is not defined. It does not require a...

    Fitting Hot Tank Thermostat

    Thanks Harry. Yes and Yes. Thermal stratification looks the only remaining answer--but never noticed this situation in the past winters. Incidentally, the thermostat bi-metal strip is kept about 1mm from the tank surface by the casing. Should this space be filled with any thermal paste?

    Fitting Hot Tank Thermostat

    Thanks Terry. I agree and that was what I tried this morning. However the water is still scalding hot even with thermostat set to 60c. Oldbuffer---the boiler control is irrelevant as it is running from the radiator heating requirements in any case, so the only control relevant to the tank is...

    Fitting Hot Tank Thermostat

    As the hot water on an S-plan system was far too hot, I worked through the following logic. The immersion heater was definitely off. There had been no recent work on the system. The cylinder thermostat was set correctly and the Myson 2 port 28mm zone valve (Neon and motor) responded to...

    MYSON Zone Valve 28mm 2port MPE228 Body swap(?)

    I am having a problem in obtaining a replacement 28mm brass body (Part No Myson 421202) for the above and the complete unit is not required. (The actuator heads are freely available, but the complete unit is attracting a premium price!). Is any one confident enough to suggest an alternative...
