💸 another week another dollar!

Understood captain 👍 If I have any left over fibreglass should I whack that in our just bite the bullet and order in more 40mm PIR?

I was going to go with expanding foam all around the perimeter? Seems to be the easiest way and what I've done in the past.

Yeah probably not really a concern seeing as it's the ground floor. I was going for the more insulation the better, seems to make sense if you can get either of the types for next to nowt/free.

Evening gents. The build-up for my suspended floor is the same as the attached image. PIR 120mm but less in places where it was necessary. My question is, the area where the support battens are, that's a void there. Would there be any benefit in running a membrane under the joists and laying in a 50mm fibreglass roll in that void area? I could also potentially friction fit/foam in another pir board of 50mm. Was just wondering if a PIR/fibreglass roll combo would provide any additional benefits. I'm aware you need twice as much fibreglass to be comparable to PIR but a mix of materials might provide untold benefits?

Could use a motorised valve connected to a leaky hose, but hardwired to a plug. Then the plug connected to something like a Tapo. "hey Google, water the garden" The tapo app lets you schedule timings etc. That's something I've been thinking of doing, but haven't looked at it in detail so far.

Just a mock up with old bits of pipe but I think it'll go in just fine. Been a long road, but fingers crossed, never even thought about the diverter valve before so hopefully that'll be dandy once rigged up to the rad zone valve.

I bought a 1" BSP tap but it was totally obvious it wouldn't go in as it was just destroying threads and then bound up. I could wind the tap into one of the other 1" ports no problem, but it was just making things worse in the bottom port so I stopped before it just made it totally unusable. All in all, an absolute (expletive deleted)ing nightmare on something that should have been simplicity itself! Anyways, I've got all the ports wound in and chemical fittings all in the chimney breast ready to go, so hopefully make progress this week. Thanks for all the help with this guys, was really at my wit's end with this.

NTP fitting... No joy, still binds up immediately. Ok so that's pretty much every fitting available so it's obviously got a thread issue. I'm going to go with the tap on the top, going into a 15mm and then the air valve. @Nickfromwales I hope you think this will do the job?

I've ordered one, last throw of the dice! 😆

Actually don't have the room underneath the tank now, the tap and drain will hit the floor. Jesus, what an ordeal. Ok so I can flip the tank and have the stupid tap/air valve combo on top, just need a 15mm - 1/2 adaptor. Been a crazy time this...

No joy. Every single thing I buy/order/try has the course thread which just isn't what I need :-(. @Nickfromwales any issue with me just using this old stop cock, left open with a drain on the end? I gotta water won't be following through it unless I drain it, it just needs to hold.

Took a punt on this, no idea of the thread so a total stab in the dark!

No joy with the 1" male iron, that didn't fit either. End of teather is approaching... The problem is the thread, I need a fitting with a much finer thread it seems and I've only ever seen that on the end of a 25mm stop tap, ridiculous! At a push... Can I just leave this old 25mm stop tap in there?

The guy behind the counter had a 1" female iron and it went onto the end of my 25mm tap no bother. Said I need a 1" male iron but they didn't have any, typical. So I'll mooch around the internet tonight to see what I can find.

For the win... Hopefully. Plumbase says it's a 1" male iron. However they didn't have any...

This picture will help no one im sure, almost impossible to get a picture of it. I would say the one I'm having problems with is 11 tpi and the ones that all work are 10tpi, but it's tricky to measure.... Might just take the fittings to a plumbers merchant if I can find one local.

Right I have no means to measure the thread sadly. Looking at this with less pissed off eyes, I'm pretty sure the thread pattern is different. The 25mm tap that actually fits in it, the thread is different to the 1" bush that doesn't. Tap on the bottom, 1" bush on the top. Every bush or fitting I've tried has that same larger thread... So that's what's going on here, I need the bush/fitting with the same thread as the tap.

it might be tricky but i will try that when i get home after work. Proper sick of it, just need to get a move on!

tech specs claim 1" top and bottom on the 50l.

difference in sizes on the supposed 1" fittings.

Tapered fitting, no dice, exactly the same as my bush. Tap, just binds up, just making it worse. Honestly don't really know what to do now, the whole thing has been a massive sink of time, money and effort... Only thing that gets anywhere near is the 25mm fitting in the stop cock. I'm debating grinding the top few threads on the tank away with a Dremel? Dont have much to lose at this stage...!

I've ordered a tapered fitting to try it out. I've got the tap but I think it's just making things worse. Glad I started this... Literally should have screwed in and job done!

yeah all other ports are BSP, go in like a dream. Not a bad shout though, but looks like its not something i can pick up on my way home from work sadly. I'll see what i can come up with. Cheers fella.

yeah i did, but it was listed as new, still had all the bungs in place. Not totally unbelievable that the seller realised the same thing as i found, but all the bungs were unmarked. I borderline had to destroy them to get them out so i dont think they had ever been removed.
