Wow camel307, that's some pretty serious attitude from a guy looking for help. What you still have not made clear is the distance from the cylinder to the pump and the gauge of pipework used. You have also suggested that the pump shares pipework from the cylinder with other outlets. Can...

I carried out exactly this procedure two weeks back on my vented system. In our case pumpover had introduced a load of air into the system and the subsequent corrosion left the water a horrible brown colour. I don't think it had got to the sludged up stage yet but wanted to do more than drain...

We have an Aga Litle Wenlcok which (I think) is about 4.5kW. We manage to heat a large room (8mx4mx2.7m) using this stove alone. However, when first installed I did not do a good enough job of sealing the register plate and we got much less air flow through the stove and the heat output was...

I have an agreement with a local plumber where I do the work and then he charges his hourly rate to check/commision anything required. So, I'd be buying and physically installing the cylinder myself. There seem to be a large number of options out there (with a multitude of different...

We have really good mains pressure/flow so I don't anticipate any problems. Cheers, iep

Looking to change our hot water cylinder as we only get 1.5 decent showers out of our miserly 110L existing tank. While we are at it, thought I'd look at geting an unvented cylinder so we can remove the cold water tank and noisy shower pump. The existing system is a basic s-plan with...

FYI, when I got home last nght it was 0 degrees outside and the heating had been on for one hour. At the insulated end of the house we have 3 large rads. The temp had reached 18 degrees (this is the temp we keep the house at) and the TRVs had switched the rads off. At the uninsulated end of...

Insulation makes a huge difference. People are obsessed with things like double glazing but it is your loft insulation that can make the biggest difference to your house. We spent £40 on insulation last year to cover half the loft in our bungalow. and it has transformed that half of the...

Thanks guys. Hi Idealboilers. Yes, still trying to get this job finished :lol: Just want to make sure I don't destroy the pump when it goes in. Feels like I have two jobs these days, my normal 9-5 and part time (albeit very slow) plumber at the weekends. Still, reckon we are getting close...

Hi, thanks for the advice. Once moved, the pump will sit directly between the vent and the bypass valve s oall should be well (just after the vent, just before the bypass). So, all should be well. Cheers, iep

I have been advised to move the pump from the return to the flow side of our boiler (after feed vent connections) to solve pump over issues at the F&E tank (and to meet manufacturers gudelines for our boiler). Currently, the pump sits directly below the boiler and pumps water upwards from the...

Maybe actually. I might pick one of those up (or similar) when I buy the parts. Cheers, iep

Thanks. Makes sense. Just wanted to be sure. Cheers, iep

Very basic question but, where there is no space for a proper pipe cutter to be used, is it okay to cut copper pipe with a hacksaw? Obviously the saw will cut the pipe but will the imperfect cut compromise the seal on a compression fitting subsequently fitted to that pipe? Cheers, iep

Expansion vessel, PRV, gauge and filling loop are all on the list for next year when we replace the boiler. For now though we just want to prevent the system from becoming airated by the pump over. In a sign from the plumbing gods, the existing pump packed in last night so it is defintely...

I'm waiting for Glowworm to get back to me with definitive advice on whether the energysaver60 can be used with a combined feed/vent and then hopefully I can get it installed and put the pump over and related system corrosion issues behind me. Thanks again to all. iep

The boiler manual refers to an overheat stat and, in fact, it triggered last winter when an air lock formed after filling (so I know t works). I guess it needs one since it can be used in a sealed system? I'm happy for water to surge up and down the combined vent/feed since it shouldn't...

Answered my own question by doing a search. This is a form of combined vent/feed. Cheers, iep

Guys, thanks for those posts. I finally understand why we have a vent and a cold feed. The cold feed is the neutral point and this isolates the vent from the pump. That has been bugging me for ages and I now get it. onlyfitidealboilers, do I take it then that the combined vent/feed is a...

Hi Picaso. I can understand why the pump is unable to push water up the vent if it is located after the vent pipe (negative pressure and all that). However, I would have thought that it is more likely to suck air down the vent in this location due to the neagative presure at the vent pipe...
