First Fix Plumbing Nearly Failed: How A Serious Oversight Almost Cost Us

[@hunterb9273]

The joist holes are not in the drill zones. Ive had building control sting me in the past on this. Need 300 to 500mm spacing on the clipping. Enjoying the videos , keep em coming

[@martinwright7093]

Great video, Luke. When you're putting in a secondary return on the hot water, presumably the main hot supply has to be copper as well because the water circulates around through both. I've seen two failures where the plastic pipe failed because the secondary was run in plastic, but the failure was in the hot supply pipe close to the cylinder.

[@kaiser9100]

Your correct Martin👍

[@bluebulldog_uk]

@@martinwright7093 The main loop will be copper and where it branches off it will be copper but you can go down to plastic as long as it away from the primary circuit…basically on this where the water is pumped around all the time it will be copper. The hot will be one big circle going around the house

[@jamescarter1088]

Secondary returns are notorious for popping leaks. The copper return wears paper thin.

[@marknaylor6420]

So does both your primary and secondary need to be in copper?

[@jamescarter1088]

@@marknaylor6420 if we are talking secondary hot water returns, then yes a secondary return must be in copper and would be 15mm and lagged, teed from furthest tap from the cylinder.

ahhhh drilling joists, used to first fix timber frame new builds in the 90's, have spent many a cold day drilling hundreds of holes in joists, we would drill through the outside timber frame skin and poke copper through, it was all copper back then. looks like a good job, good luck wiv it.

[@bluebulldog_uk]

@@plumbingFC so what we did feeding it through wall is nothing new then by looks of it 😂 I bet it was a lot harder all in copper…also did you find you was pulling wood chipping out your hair for bloody days after 😂👍

[@b1h2u3p4]

Nice work

[@hunterb9273]

Use mlcp for the secondary return.

[@benchippy8039]

I let the smoke out of my core drill, plumber I was working with had the Milwaukee hole hawg, we used that to drill a couple core holes and they drilled quicker than the core drill would. Monster drill, dunno if i could justify the expense but it’s a proper drill bruv

[@bluebulldog_uk]

@@benchippy8039 yeah I’ve heard the Milwaukee one is a monster as well but again it’s justifying the cost

[@benchippy8039]

@ I’m a chippy by trade, don’t have much call for it. Ripped a 110mm core through that 9” wall tho! Could buy a 36v mitre saw for same sort of price, that’d make its money a lot quicker

[@effervescence5664]

I have one of those Dewalt 54v drills, they launched an 18v version last year but you have to order it in from the US. Or just buy the Milwaukee Hole Hawg 18v.

[@stephenedwards9872]

Very interesting and I'm not a plumber

[@davidb2464]

Balanced cold???? Never done such a big job like this, what is the balanced cold, is it for bigger houses?? Please let me know!!

[@bluebulldog_uk]

It means the hot and cold will be balanced so if they are run off the same time like on a shower you haven’t got one with more pressure than other, comes off pressure reducing valve when installed 👍

[@michaelbolt4530]

Fascinating video, especially feeding copper through joists, I don’t know how you remember what each pipe does is have to put labels and red tape on to remember

[@kierenhudson6331]

22mm pipe is radiator feed and return. Most radiators are bi-directional valves. The 2 smaller ones are hot and cold water Gas supply is always 22mm too and identified easily 👌

[@michaelbolt4530]

@ he mentions a by pass pipe, what’s that for?

[@kierenhudson6331]

@michaelbolt4530 I'll have a look back. If I'm not mistaken it's the full loop for the boiler but a general bypass is for if there's a fault

[@michaelbolt4530]

@ ok

[@bluebulldog_uk]

@@michaelbolt4530 it can get confusing, the hot is easy as that’s the copper pipe, it can get confusing but honestly when your on the site and working with the pipes you start to learn which is which. By pass is for boiler so when the zone valves shut down and the pump overruns, it can return to the boiler on a loop

[@alshore6168]

Thanks for the insight into first fixing Luke, but I still don’t understand how you keep track of what pipe is what, do you have to know which pipe is which at every radiator? I’m looking forward to the underfloor heating going in. 👍

[@bluebulldog_uk]

@@alshore6168 it can hurt your head but we have tape on hot and cold pipes and when your working on it all day you start learning the routes and what’s what..suppose it helps I’ve filmed it as well

[@ieuanhughes8521]

Hi Luke love your video. Dewalt have a 18v angle drill now DEWALT DCD444N-XJ 18V👍

@@ieuanhughes8521 is this more money to spend 😅😂😂👍👍

[@paulgilliland2992]

If your main water pressure is too high , why not throw a prv on the main ? All your appliances and equipment will state max operating pressure in their manual . We’ve seen lots of claims for damage caused by excessive water pressure denied because of this.

[@TomChapman-wv9iq]

If they get that done in 3 weeks I would be amazed lol

[@alimack5489]
