macgee - i'm sorry was just checking every possible solution!! this is a weird one. hope it gets sorted out soon and a solution is discovered.

i was wondering if the f & e was not at least 1 metre above the primary vent it could cause pumping over , but missed half this post so gotta catch up!:) pump positioning/speed setting could also play apart in this. the pump head/3 rule is true ... :)

yep the 2 steel rule is good - i was taught that and the mckeown's rule for going back from marked point. i did a 45 for a 65mm diatance (width) between 2 joints (using 2 pieces of scrap pipe) and it was not good!!! so gonna do it again (tomorrow now)!:) to 30

umm sorry for misreading. the cold feed is also the expansion tank for when the CH /primary water is heated. what's the distance roughly from your feed and expansion tank and your primary flow to your hot water cylinder?

why would a blockage somewhere down the pipe cause water to come out of the vent?

that's my original point!! when pulling the offset the offset itself was too big, eg one bend to the other fitted the space and there was no room for the straight ends to insert into the fittings at each end!!! - as the other poster mentioned, i needed a smaller angle 30 degree ... nothing to...

this is a weird one - i wanna find out the answer to this! :) i'd lay money on it being he coil though - if the pipe was blocked somewhere then the water wouldn't be able to come out of the vent would it? very tricky !...

can't as the distance (height wise) between the 2 fittings won't allow it!! :)

while i'm on the subject of copper pipe! :) and on the net - can i ask a simple question to you - when a soldered joint is made, if the silver ring isd all the way around, then the joint is good isn't it ... ? one of those days :)!

thats what i was thinking. actually i just remembered, i need 2 folding steel rules- 600mm deduct the length between bend - in my case 65mm from 600 - put my other steel rule on 535 and bend to that angle!! just came back to me ......

it must be a hole in the coil 0 what other explanation can it be?? can't be a blocked cold feed as there is still water in the system i take it??

Hi I have been making a 15mm offset using a hand bender - I pulled it to 45 degrees and the distance between the two fittings was 65mm. so i marked 2 lines on paper 65mm apart. i made the first bend and layed it on the template (on the paper) and marked the position for the second line. I...

i found with the drop valve that the oveflow level is well under the inlet leel and they are generally a lot smaller than the normal siphon type devices. i also found that they have a more powerful flush and only use a tiny amountof the cistern water (compared to the siphon type)!!!

as new ly installed boilers now have to have a SEDBUK rating A or B - and these are condensing type boilers: does it mean that if replacing a boiler (eg my potterton flamingo-i have to get a condensing type? and these condensing type boilers are system boilers that have the pump, etc built in...

well i would suggest if te pipes looks ok (no green coating visible) then thry should be fine. if you put similar size rads on then not much pipework will be required (if any) so it shouldn't be a prob. just hold the valve body carefully with 1 wrench when undo the possily stiff compression...
