    Pipe size for heat pump system

    I am sizing the central heating pipes for a complete replacement. The property has an elongated floor plan so I have used a piping layout consisting of single flow and return headers running the length of the property and take-offs to and from radiators. Currently there is a combi boiler...

    Macerator pipe layout

    Hi all, Flicking through my instructions for my Macerator flo force and it says “discharge pipe length before first elbow 0.5m” Having a look at other brands I can’t see this rule so wondered how important it is? My plan was to drop 0.1m then use 2 45degress into a 1.5m horizontal run. Would...

    Blocked GCH pipe to towel rail. Can I just swap to electric?

    Hi I’ve got a blockage somewhere that’s preventing the GCH bathroom towel rail from heating. Plumber has offered to try and resolve it at £100/hour. It sounds like there’s no guarantee the blockage can be found and/or fixed. So I could be pouring money down the drain trying to resolve the...

    Is 22mm supply pipe always required for combi boilers?

    Hi All, I need your advise as I'm really concerned here. I only just had regular boiler replaced with combi (Vaillant ecoFIT Pure 25kw). I had few surveys done and everyone stated the gas supply pipe from the meter to the boiler must be changed from current 15mm to 22mm. The plumber I used said...

    Cost to lift floor and replace kitchen waste pipe

    We have just had a drain specialist in greater Manchester who said that our builders (uncontactable) laid our 40mm pvc waste pipe from the kitchen island to outside (about 3 meters, suspended floor, just about a crawl space underneath when floor lifted) too flat and there’s standing water, smell...

    Kitchen sink plug hole/waste pipe leak

    Hi there Could someone help identify the waste pipe (think that's what it is) coming from the bottom of the basin/plug hole, feeding into the other pipes? It has a leak where it connects to the bottom of the basin, so I'm thinking about replacing it if it's a standard part. If so can you tell...

    Soil vent - reduced pipe size

    Following a first-floor bathroom remodel done poorly by a plumber in our house a couple of years ago I have stripped everything out and I'm starting over and plan to install our original 'vision' carefully and properly. I found that the 110mm vent stack was terminated just below a hole in the...

    Water softener waste pipe discharge

    Can the discharge and overflow pipes from a water softener go to surface water drainage (soakaway in my case) instead of foul? I'm first of all trying to find out if they are guidelines or in Building Regs, alternatively, I can probably run some calculations to compare how much regen water will...

    How to connect to this soil pipe

    I took the boxing out from around this toilet yesterday to find this old style clay(?) or concerete (?) soil pipe. The existing toilet has a 90 deg spigot on the back but obviously the replacement is a nomal modern one. Can I just break the solid seal around the old spigot, whip it out and then...

    Water keeps running out of pipe?

    I’ve got this pipe outside which water is constantly coming out of the bottom as you can see. I’ve tried turning the blue fitting but it doesn’t stop it at all. I’ve got no idea why the PRV is there or what it’s for, can I just take it off & replace with a new one & turn it off on that?

    Single pipe systems - can I reverse the flow

    I have a single pipe system retrofitted to a 1930's house. It is powered by a condensing gas boiler. As expected, the radiators get cooler the further they are from the boiler. It occurred to me that if I fitted a "crossover switch" between the punp and the radiators I could send the water...

    When connecting a plastic metric waste pipe from a bath to a metal imperial pipe in the wall is it standard practice to use denso tape on the outside of the join? Does it stop potential leaking or movement?

    Pipe sizing for LPG boilers

    Gas safe registered but not for LPG. Have been asked to quote for a number of LPG boilers so if I get the job will do my LPG ticket. But was wondering if pipe sizing is different for LPG than natural gas.
