Scott Posted April 28, 2015 Share Posted April 28, 2015 I'm looking for a bit of info as I'm struggling a bit to find a solution. I'm looking to make a bottom drain for my boiler, currently it's a side exit. What fitting can I use for the drain itself? I have a 1/2" female 90 deg elbow for underneath the boiler but I can't find anything that's a "drain" to connect to it. At the moment I've got a reducing bush, that would do the job nicely if it wasn't for the lack of flange..... I just don't think I'll get a good enough seal, even with a washer, due to the lack of flange. Any help would be appreciated Scott Quote Link to comment Share on other sites More sharing options...
Scott Posted April 28, 2015 Author Share Posted April 28, 2015 What about a half socket? Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted April 28, 2015 Share Posted April 28, 2015 I have an encyclopedic knowledge of plumbing fittings (I wish I was joking ), but I can't picture what you're trying to do. Are you talking about the condensate overflow pipe? Quote Link to comment Share on other sites More sharing options...

Scott Posted April 28, 2015 Author Share Posted April 28, 2015 I have one of these..... http://www.caterfor.co.uk/images/products-large/CF-CC191.jpg As you can see it has the tap coming out of the side. I'm changing this to drain from the bottom instead of the side..... like this... The kit I currently have is as follows.... The red box shows the bottom/side of the boiler. The fitting in the 90 deg elbow is the reducing bush that I was going to use, but the hex flange on it is minimal so I can't even use a washer on it. The ideal solution for me would be said reducing bush with a better flange on it. Cheers for the help Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted April 28, 2015 Share Posted April 28, 2015 A 1/2" Cylinder boss would be ideal for this Or a 1/2" header tank boss/connector if there's room. Quote Link to comment Share on other sites More sharing options...
Scott Posted April 28, 2015 Author Share Posted April 28, 2015 Bingo, those both look ideal! Many thanks Can't find either in stainless Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted April 28, 2015 Share Posted April 28, 2015 You won't (not from a plumbers merchants at least), but why can't it be brass? Brass fittings are fine on potable water storage. Quote Link to comment Share on other sites More sharing options...

Scott Posted April 29, 2015 Author Share Posted April 29, 2015 Crikey, that's some serious cash It's not for water, it's for homebrewing. I'm going to make the boiler into an all-in-one, start to fermenter brew machine. What I need to do is have the option of emptying the brew into a bucket or re-cycling it over the top of the grain. My head tells me that there may be a chemical reaction with the enzymes of the brew, the stainless of the boiler and the brass of the fittings. Everything else I have bought it stainless so I would prefer to keep it that way. Unfortunately I can't afford shipping costs from the US or justify £50+ for a simple fitting. I'm going to go with a straight 1/2" nipple and a half socket, along with a nitrile washer. Hopefully that should see me OK Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted April 29, 2015 Share Posted April 29, 2015 I would imagine it would be fine Sadly stainless stuff like bulkhead fittings is specialist, and therefore expensive. Quote Link to comment Share on other sites More sharing options...
Scott Posted April 29, 2015 Author Share Posted April 29, 2015 Found this...... http://www.ebay.co.uk/itm/1-2-BSP-Stainless-Steel-Skin-Fitting-Deck-Fitting-/221724558734?pt=LH_DefaultDomain_3&hash=item339fd0458e Looks ideal, so if I get no luck with my current plan I'll give it a go Quote Link to comment Share on other sites More sharing options...
Hitbox Junkie Posted April 29, 2015 Share Posted April 29, 2015 Do we get samples? :) as above stainless is exspensive what about welding stainless fittings you want? Quote Link to comment Share on other sites More sharing options...
Scott Posted April 29, 2015 Author Share Posted April 29, 2015 Do we get samples? :) as above stainless is exspensive what about welding stainless fittings you want? I don't weld and I really don't fancy carting around the big ass boiler Sending out samples is too costly unfortunately, costs me the bottle and the postage.... ends up way more than a beer lol. Anyone is welcome to sample at the house though Quote Link to comment Share on other sites More sharing options...
Shane Posted April 30, 2015 Share Posted April 30, 2015 How about a pushfit plastic tank connector? Less than a couple of quid from Toolstation. I guess they would take the temperature, you could boil one up first to see how it survives. http://www.toolstation.com/shop/Plumbing/d20/Pushfit/sd3143/Tank+Connector/p53963 Quote Link to comment Share on other sites More sharing options...
Scott Posted April 30, 2015 Author Share Posted April 30, 2015 Went with this in the end.... http://www.norfolkmarine.co.uk/shop-online/images/4080428l.jpg I've got another query now though...... I've got a 3/4" hole that I need to put a temperature probe though. Is there some sort of compression fitting that encloses the inside? I've used similar items with electrical boxes to keep out the moisture but I need something that'll hold the water while allowing the probe through.
