Thanks Vinn, I've looked at those and they say for usecwith 65mm sq pipework, whereas we have 100mm

Hello, I wonder if anyone can help with this query. We have a 100mm square RWP that needs connection into circular below ground drainage pipe work. Is there a socket/connector that will enable a square fitting of this size to securely connect to the below ground drainage ? Or do we need to...

Hi, I need to bleed a radiator, as it is cold at the top of the radiator when the heating is on. The problem is I cannot seem to undo the radiator valve. It's a typical Stelrad type radiator with a square bleed valve, I've tried with 2 or 3 different bleed keys but it won't loosen ! I have...

If it had been a concrete screeded deck substrate, then the vents could of become redundant as they would have been there to ventilate and allow the drying process of the concrete, but this is not the case in this situation. So unless they serve redundant equipment below, they should be replaced.

I've tested the incoming main water and its hard to be exact but our incoming rate is approx 15-16 l/m or maybe slightly more, it's difficult to be exact. We have good mains pressure.

Yeah I tested the existing flow rate and it was approx 11-12 l/m from the Powermax 185 boiler. The Potterton comes with a five year guarantee, it sounds quite a good unit.

Hi All, I'm considering a Potterton Titanium 40kw unit which delivers 16 l/min flow rate for £1600 suppled and installed, with a 5 year warranty. I think they are a recently released boiler. What are your thoughts on these boilers ? Regards,

Would I gain much by installing a Vaillant 837 instead of the 831 model. We have a 2 bed semi-detached with one bathroom. Or is that just unnecessary overkill ?

Thanks for your help Dan.

Dan_Robinson, Are the Intergas boilers only installed by Approved Installers ? We are based near Ipswich in Suffolk. Are they easy to work on, and a large percentage of Engineers happy to work on them ? This is important to me, because the Powermax was notoriously impossible to get anyone to...

Thanks Dan / Mickyg for the replies. I will get the output measured. That has been my concern regarding the hot water output as we do get an excellent supply with the Powermax, it's a shame no one is prepared to work on them !!! Of the three quotes I've had they all recommend the Vaillant...

Thanks for all the replies. Dan, I've never come across the Atmos boiler. Does it compare well to the Vaillant, technically and economically ? I've been quoted £1700 to supply & install the Vaillant 831 boiler including power flush. Regards,

By the way the reason we are replacing the Powermax is because it constantly leaks, and it's impossible to get anyone to repair / service it. We also have small microbore pipework, is there a high chance of getting potential leaks in the pipework when introducing a sealed system which must be...

Thanks for the reply. We have a Range Powermax 185 boiler, which has an F&E tank in the loft. The suggestion has been to replace this unit with either of the previously mentioned combi's which I believe are fully sealed systems, so the F&E tank will become redundant. I'm unsure if we...

Hi, We are in the process of replacing a Range Powermax boiler for a new unit. We have good mains pressure on the cold incoming, and the Powermax currently operates a shower directly very well. We have been recommended either a Vaillant 831 Eco Combi or a Worcester 30CDi. We have a 2 bed...

Hi All, I'm considering either a Vaillant 831 or Worcester 30 CDi boiler. Is there much between these boilers, as they are a similar price. I'd like the consensus on which is regarded as the best bet. Regards,

Yes the area might help ! The area concerned is no more than 12m2.

Hi, I've received two quotations for the following work; Had an extension built, I've currently lifted the existing paving slabs, dug out an existing lawn area and loose laid the paving to make sure it fits ok, and now require my existing slabs re-bedded properly in a full screed / mortar...

Hi, I've dug out a small area I want to pave in my back garden, and compacted the soil down tight. It's really firm in place, will it be ok to install pavers on a 25mm layer of slablayer directly to the soil ? Then point the slabs with mortar in the joints. Cheers,

Hi, Thanks for your answers. I've tightened it as tight as I can get it, and removed it and the washer is intact. The open thread on the isolator must not be mating with the washer enough to prevent it leaking. I think the weakness is that I'm trying to connect a flat surface washer onto...
