    Soil pipe repair plastic to clay

    I’d agree about replacing / redoing the clay below ground drainage but it’s hardly a diy job and in the current climate... lord knows when it would be done :p

    Soil pipe repair plastic to clay

    or perhaps one of these rubber sliding joints, they can be easier to fit to existing systems https://www.drainagecentral.co.uk/Flexseal-100mm-115mm-Drainage-Coupling-DC115?gclid=CjwKCAjwg6b0BRBMEiwANd1_SA--RwetZLDNMCN-GFn0t_HPqCBnWRFTr6PvoaCOKcbv-PlG9LAq-hoCwQsQAvD_BwE

    Leaking/Whining Unvented Cylinder

    Looks like it is on 0.3 now. Try 0.2 see if the noise stops. Adjust it via the black plastic nut. Anti clockwise

    G3 Registered, replacement control valve blowing off

    Just popped in on the way home and the balanced cold of the control has been capped. So the back pressure theory is looking likely. I just had a thought, could I just fit a 22mm double check valve on the dhw draw off? Im also thinking of fitting a prv after the mains stopcock as it’s easily...

    G3 Registered, replacement control valve blowing off

    Thanks I’ll look into back pressure. It’s looking like a tap or shower may have failed. The control valve and expansion vessel were replaced like for like recently. I’m sure both are correct One of my pet hates of unvented is expansion vessel at bottom of the cylinder as that means you have...

    G3 Registered, replacement control valve blowing off

    Hi Guys Just wanted to pick your brains on this one. (I'm g3) Customer has a 250 litre un-vented cylinder in his loft. He called me to the blow off dripping outside. The expansion vessel had failed and it was fitted at the bottom of the cylinder on the floor of the loft. The control valve...

    Leaking/Whining Unvented Cylinder

    To the left of the picture, bottom left you have an auto byepass valve, this may need adjusting. You can open it a little more but don’t open it too much as it’s a direct route back to the boiler, too much and the radiators won’t get hot. I think I can also see a lever valve on the return...

    Leaking/Whining Unvented Cylinder

    Sounds like air in the system generally, try bleeding all high spots usually towel rails / radiators on the top floor. Don’t forget to top the pressure up via the filling loop next to the gauge. To around 1.25 bar. There is also an automatic air vent next to the filling loop which is the most...

    Someone got to start this one 🤔

    Why is it that the individual needs money for a rainy day but when banks or large companies struggle they come cap in hand to the taxpayer? Remember the billions that went to the banks 2010? One thing I'm glad to see in this crisis is money actually going to the people that need it and from a...

    Someone got to start this one 🤔

    The key wording seemed to be "You can travel to and from work only if you can't work from home" Now obviously we can't work from home and nor can most trades. However if the merchants close because they are a "non essential business" then the materials will dry up... so the building sites may...

    Someone got to start this one 🤔

    There’s an interesting dilemma going round my head about the gas safety checks. Essentially I am putting the virus above them in a risk assessment. I’ve serviced them for years, I’m 99% sure they are perfectly safe but legally they are due and the landlord would be liable if anything happened.

    Someone got to start this one 🤔

    In the light of the figures in Italy... 800 dead yesterday! I’m thinking of changing my approach. I’m due to visit 4 different properties tomorrow. Two gas safety checks, 1 service and replace a unvented control valve. I’m seriously thinking about rescheduling the gas safety checks and the...

    Someone got to start this one 🤔

    I’ve noticed customers delaying bigger jobs. Simply because they don’t want to be in the middle of a kitchen refurb and no one turn up for 4 weeks! I’m getting maintainance work, in fact one customer said “ I don’t think British Gas will be doing my gas safety checks and that made me think do...

    Someone got to start this one 🤔

    Let’s get a sense of perspective 170,000 cases worldwide, out of 7.5 billion. 1500 cases in England out of 60 million plus. I really think the media is creating panic and I’m not really sure why. The actual health condition of the virus is very mild, only fatal in 1% of cases and that figures...

    Old Viessman vitodens 100 combi problems

    Managed to get it going again, the left hand isolator on the flow side was partially blocked / closed and once I got that flowing I got a fair bit of air through by flushing through with an external filling loop. The pump was actually fine, I couldn’t stop it thanks. One thing I noticed...

    WB Greenstar 30 cdi problems

    Lets be honest, the access on that boiler is shocking. It looks like someone has built that wall / bulkhead infront of the boiler. Especially bad on this model of worcester as the casing comes forward quite alot to be removed. If you look in the manual it will give you the minimum clearances...

    Old Viessman vitodens 100 combi problems

    Hi guys, Just replaced some radiators in a recently purchased student let. The boiler is a 12 year old vitodens 100, 7248589. I tested the heating and hot water before draining down and it seemed to be working, maybe a little lack lustre on the heating. After completing the rads, refilling...

    Hot water dominating central heating?

    Is there a gate valve on the cylinder return? I usually fit one to aid in balancing the coil with the radiator circuit. If its close to the pump you have to have it 3/4 closed or thereabouts Surely its not 15mm to all 9 radiators from the pump?

    Replacing boiler for combi. Fair price??

    "Reasonable" varies according to location and the installation required. However I would confidently say I could beat that price in most cases. Ask around your friends and family, they might use a plumber you can recommend.
