    Septic Tank Ventilation Design

    If you follow Klargesters advice I think that you will have sewage smells coming out somewhere else instead, like shower trays, sinks, etc. A soil vent pipe is a VENTING pipe, not an air addmittance pipe. They were not called 'Stench pipes' for nothing as they let the smells out into the...

    pureflow septic tanks

    Sounds like you have a real beauty for a service engineer! 3 weeks??!! You can't leave them for more than 3 days without bacterial death! You are risking the diffusers blocking and that is a big job with one of these as you can't pull them out. Did he do a sludge core sample as it will almost...

    pureflow septic tanks

    Hi, Firstly, you have a sewage treatment plant, not a septic tank. I have installed a lot of PureFlo's (now called 'Falcon', I believe?) and they are very good plants. It is essential that you replace the blower and leave it switched on. The sewage plant also needs an annual service or it will...

    septic tank puzzle

    The vent pipe on the old tanks was to let the septic tank gases out, not to allow air in, so an air admittance valve would be defeating the object. Septic tanks produce methane and hydrogen sulphide gases which must be relaesed to the atmosphere. They do smell, but in the old days, no-one...

    Septic tank soakaway

    Jeds is right, but over 60% of all sites are currently failing the 3 mandatory tests for installing a replacement soakaway, so be warned. The tests are as follows: Groundwater Source Protection Zone search at the E.A. Trial Site Assessment Hole Percolation Tests Most of the soakaways I am...

    smelly waste

    Nige F is right. I am not a clairvoyant, but I bet you have installed one of these 'low profile', shallow shower trays? These have useless 'Continental' traps which are not 'traps' at all, but merely shallow sumps to trap hair, grit etc. They DO NOT stop smells coming back from the drains and...

    Serious question here (old septic tank)

    All septic tanks have to be emptied and that includes all chambers, every year, (though a lot of tanks go 30 years before the owners empty them!). They must, therefore, have an access to all chambers. Sometimes it means that the entire concrete slab top has to be slid aside and I would guess...

    Non-mains Services

    Problem is that if a plot of land gets PP for a residential caravan, without a business clause, its value rockets, as it would also get PP for a house. No way will the Vendor sell it to you for the price of land without PP. I have seen it so many times. All you will do is put money in the...

    Non-mains Services

    It is almost impossible to get P.P. for permanent residential caravans. People get PP for them to live in while they are converting a barn, renovating a house, etc. but not for permanent homes unless it is a Residential Park development. It is as hard to get PP for a permanent caravan as it is...

    Soakaway Problem

    Firstly, a soakaway 'pit' is ONLY to be used for surface roof water, not septic tank effluent. Pits do not work for septic tank effluent as, unlike rainwater, you will be discharging into it every day and it never gets a chance to empty. Pits are not allowed under Section H2 of the Building...
